The Glacier.
The Falls. The Tango.
The Steak.

Buenos Aires (the capital of Argentina — founded twice (the first attempt in 1536 abandoned after conflict with indigenous peoples — the second founding in 1580 by Juan de Garay — the city that has been continuously inhabited since) — metropolitan population approximately 15 million — the most European city in South America in architecture, in cultural sensibility, and in the specific melancholy that the Argentines call “porteño” (the quality of being from the port — the Buenos Aires disposition, the mix of pride, nostalgia, and slightly theatrical suffering that the guide describes as “the specific emotional register of a city that knows it was once among the wealthiest in the world and has complicated feelings about what happened next”)) is a city that rewards walkers, eaters, and anyone willing to stay up past midnight. The tango (the dance that was born in the late 19th century in the conventillos — the crowded tenement boarding houses — of the San Telmo and La Boca port districts — the dance of the immigrant underclass (the Italian, the Spanish, the Polish, the Eastern European Jewish immigrants who arrived at the port of Buenos Aires between 1880 and 1930 in one of the largest voluntary migrations in human history — the guide’s position: “the tango is the most honest available account of what it feels like to arrive somewhere new and not know how things work — the dance was invented by people who did not know how things worked — the dance shows this”) — the milonga (the tango social dancing event — not the tango show for tourists, which is choreographed and technically excellent — the milonga is the social dance event where Argentines who learned tango from their grandparents dance with strangers according to a specific social protocol (the cabeceo — the invitation by nod across the room — the guide explains this before bringing the group to a milonga — the group observes but does not attempt the cabeceo — the guide has observed this instruction being disregarded twice — both occasions were instructive)). The barrios: San Telmo (the oldest neighbourhood — the colonial-era streets — the Sunday feria (the antique market) — the tango dancers at street corners), Palermo (the largest barrio — further divided into Palermo Soho (the designer boutiques and restaurants) and Palermo Hollywood (the media production studios and the best restaurant strip in the city)), La Boca (the colourful corrugated iron buildings of the Caminito street museum — the guide’s instruction: stay on Caminito — the streets beyond are a different environment — the guide states this without alarm and the group follows the instruction). The parilla (the Argentine steakhouse — the grill — the guide’s steak briefing: the Argentine beef (the grass-fed Pampas cattle — the guide explains the Pampas (the 750,000 km² of temperate grassland that covers the central provinces of Argentina — the grassland that feeds the cattle that produce the beef that the guide considers the finest available anywhere on Earth — the guide has been challenged on this and has not modified the position)), the cut (the guide orders the bife de chorizo — not a chorizo sausage — a sirloin cut specific to Argentine butchery — the guide explains the confusion before the group asks), the cooking (the parrillero (the grill master) — the hardwood charcoal (the quebracho — the Argentine hardwood that burns hot and slow — the guide identifies the quebracho smoke before the restaurant is visible), the point (the guide orders the beef “a punto” — medium — the guide notes that ordering well-done in a Buenos Aires parilla is a social choice that the guide will not judge but will note))).

• Tango · born in tenements of San Telmo and La Boca · immigrant working class origin
• Milonga (social tango) · the cabeceo invitation by nod · observe but don’t attempt
• Bife de chorizo · grass-fed Pampas cattle · quebracho charcoal · order “a punto”
• San Telmo Sunday feria · La Boca Caminito · Palermo restaurants · Recoleta cemetery
• Porteño emotional register · “complicated feelings about what happened next”

The Perito Moreno Glacier (the glacier in the Los Glaciares National Park — UNESCO World Heritage since 1981 — accessible from the town of El Calafate in Argentine Patagonia — 80km by road from El Calafate — a 30km-long, 5km-wide river of ice descending from the Southern Patagonian Ice Field (the third-largest freshwater reserve on Earth after the polar ice sheets)) is one of the few glaciers in the world that is not in significant retreat (the Perito Moreno advances at approximately 2m per day and calves at approximately the same rate — a dynamic equilibrium — the guide’s description: “most glaciers are retreating — the Perito Moreno is roughly breaking even — this is not a success story but it is a different story from most”). The calving (the ice calving from the glacier’s face — the terminus of the glacier reaches the southern arm of Lake Argentino and intermittently dams it — when the pressure builds, sections of ice — the guide estimates the smaller calvings at the size of a 5-storey building and the larger at the size of a city block — break from the face and fall into the lake with a crack that is audible from the boardwalk system approximately 200m away — the sound: the guide describes it as “a specific combination of rifle shot and thunder — it cannot be described adequately — the first calving the guide witnessed was in 2008 and the guide still turns toward the sound before the thought completes”). The boardwalk system (the steel walkway and viewing platforms that run along the southern bank of Lake Argentino facing the glacier terminus — approximately 3km of walkways at various levels — the guide takes the group to each level and identifies the best calving zones — the southern sector of the glacier face has historically produced the largest calvings — the guide positions the group at the southern viewpoint from approximately 10am and considers the wait not a wait but an occupation). The glacier walk (the mini-trekking option — the guided walk on the glacier surface — the crampons, the ice axes — the specific blue of the ice seen from within 5m — the guide’s position: “you cannot understand how blue glacier ice is from the boardwalk — you can only understand it from 1m above the surface — if the group has the fitness for the walk, the walk is correct”)).

• 30km long · one of few non-retreating glaciers · 2m advance per day
• Calving · “rifle shot + thunder” · audible 200m away · guide turns before thought completes
• Boardwalk system · southern sector best calving zone · guide positions from 10am
• Mini-trekking on glacier · crampons + ice axes · the specific blue seen only from 1m
• Los Glaciares NP · UNESCO 1981 · 80km from El Calafate

Torres del Paine National Park (Parque Nacional Torres del Paine — the Chilean national park approximately 2 hours by road from El Calafate across the border — the three granite towers of Torres del Paine (the “Towers of Paine” — the three monolithic granite spires rising to 2,850m (Torre Sur), 2,800m (Torre Central), and 2,600m (Torre Norte) — the towers formed by the magmatic intrusion of granite into older sedimentary rock approximately 12 million years ago, followed by the glacier erosion that exposed and carved the current profiles — the guide’s geological briefing at the trail start: “the granite was always there — the ice carved everything else away — the towers are what remains when the ice removes everything softer”)) is the destination that consistently tops the “world’s best hikes” lists and consistently delivers the experience those lists describe, which is unusual. The W-Trek (the 5-day circuit of the park — the standard multi-day trek — walking the shape of the letter W — covering the Mirador Las Torres (the hike to the base of the towers — the lake at the base — the reflection of the towers in the moraine lake at dawn — the guide’s standard instruction: “the 4am start is not optional — the towers are in cloud by 9am on approximately 60% of days — the 4am departure catches the light and the reflection — the group protests at 3:30am and stops protesting at the lake”), the Valle del Francés (the hanging glaciers — the granite walls — the condors (Vultur gryphus — the Andean condor — the 3.3m wingspan — the bird visible at the Valle del Francés on the majority of visits — the guide does not promise the condor — the guide’s instruction: “look at the top of the granite wall — not the sky — the condor is often visible at the ridgeline before it launches”)), and the Glacier Grey (the Grey Glacier — the accessible face of the Southern Patagonian Ice Field — the blue icebergs in Grey Lake)). El Chaltén and Fitz Roy (the Argentine village at the base of the Fitz Roy massif (Cerro Fitz Roy — 3,405m — the jagged granite peak whose silhouette appears on the Patagonia clothing brand logo — the guide notes this connection without endorsing any commercial interpretation of it — the mountain predates the brand by a geological epoch) — the Laguna de los Tres day hike (4–5 hours ascent — the view of the Fitz Roy towers from the moraine above the lake — the guide’s description of arriving at Laguna de los Tres: “the view at the top of the scree is one of the most abruptly extraordinary things that the Argentine landscape does — the guide has been here 40 times — the guide still pauses at the ridgeline before looking up”)).

• W-Trek · 5 days · world’s best hike lists · consistently delivers
• 4am start for Torres · reflection in moraine lake · in cloud by 9am on 60% of days
• Andean condor · 3.3m wingspan · look at ridgeline not sky · visible at Valle del Francés
• Fitz Roy · 3,405m · the Patagonia logo · Laguna de los Tres abruptly extraordinary
• Guide pauses at the ridgeline before looking up · 40th time · still

Iguazú Falls (Cataratas del Iguazú — the waterfall system on the border of Argentina and Brazil — the Iguazú River (a tributary of the Paraná River) dropping 60–82m over a 2.7km horseshoe-shaped escarpment — 275 individual cascades (the number varies with water volume — in flood season the cascades merge into approximately 150 — in low water they separate into 275 — the guide uses the low-water figure as the benchmark because the individual cascade character is most visible) — UNESCO World Heritage on both the Argentine side (since 1984) and the Brazilian side (since 1986) — the most visited natural site in South America) are the waterfall system where the guide consistently encounters visitors who have seen the photographs, managed their expectations, arrived at the Garganta del Diablo (the Devil’s Throat — the main horseshoe cascade — the largest single drop — the viewing platform at the edge of the Throat) and stopped speaking for a period the guide clocks at an average of 4.2 minutes. The guide has been timing this response for 11 years and considers the data significant. The Argentine side vs the Brazilian side (the guide’s comparison, delivered before departure from Puerto Iguazú: “the Argentine side you are inside the falls — the water is on your face — the sound is total — you are in the falls. The Brazilian side you are looking at the falls — the panoramic view — the full scale — you are opposite the falls. The correct visit does both. The guide recommends the Argentine side first because disorientation before panorama is the correct order”). The Garganta del Diablo (the walkway system that extends to the edge of the Throat — the platform at the Throat’s lip — the spray — the guide’s waterproof briefing (“any camera that is not rated waterproof will be wet — the guide has a dry bag — the group uses the dry bag — the guide has one camera casualty in 11 years — a tripod-mounted DSLR — the photographer knew the risk and the guide respected the decision”)). The coatis (Nasua nasua — the ring-tailed, raccoon-related mammals of the Iguazú forest — bold, habituated to visitors, and specifically interested in unattended backpacks and food — the guide’s instruction: “hold your bag — do not feed the coatis — a habituated coati is the most persistent mammal you will encounter outside of a museum gift shop”)).

• 275 cascades · 2.7km wide · 4× wider than Niagara · UNESCO Argentina + Brazil
• Garganta del Diablo · average 4.2 minutes of visitor silence · guide has been timing 11 years
• Argentine side first · disorientation before panorama · then the Brazilian view
• Waterproof everything · dry bag available · one camera casualty in 11 years
• Coatis · do not feed · “most persistent mammal outside a museum gift shop”

Mendoza (the city and wine region in the eastern foothills of the Andes — the province covering the Precordillera range from approximately 760m (the low-altitude Luján de Cuyo sub-region) to approximately 1,500m (the high-altitude Uco Valley — the Viños Chicos and Gualtallary areas that now produce what the global wine press considers Argentina’s finest single-vineyard Malbecs)) is the destination where the guide is most frequently asked “why didn’t we book more time here?” — specifically by visitors who allocated 2 days and discovered they needed 4. The Malbec (the grape — Malbec (Vitis vinifera ‘Cot’ in France — where it originated in Cahors in southwest France and was brought to Argentina by the agronomist Michel Aimé Pouget in 1853 — the grape that performed modestly in France (where it was a blending variety) and spectacularly in Mendoza (where the high altitude, the intense sunlight, the low humidity, and the cold nights produced a grape of extraordinary depth and fruit concentration — the guide’s summary of the Malbec migration: “Malbec left France for Argentina in 1853 like many people who had not yet found the right conditions to become what they were capable of”)). The altitude effect (the guide’s standard winery talk: “at 900m altitude, the UV radiation is approximately 40% higher than at sea level — the vine responds to UV stress by producing thicker skin and more polyphenols — this is the same mechanism that produces a suntan in a human — the vine’s suntan is the colour, tannin, and antioxidant complexity in the glass — the Uco Valley at 1,400m is the vine at maximum stress — the result is not a comfortable wine — it is a wine that has worked for what it is”). The winery visits (Zuccardi Valle de Uco (the guide’s preferred winery — the stone architecture on the Uco Valley plain — the view of the Andes from the winery terrace — the Zuccardi family’s soil classification project (the most comprehensive soil mapping of a single appellation in the southern hemisphere — the guide explains the soil classification (the different alluvial profiles — the sand, the clay, the loam, the schist — and their effect on the grape) and the group tastes in the order the guide specifies — the guide specifies an order and does not apologise for it — the Catena Zapata museum winery (the Mayan pyramid-inspired architecture — the high-altitude Adrianna Vineyard), and the Achaval Ferrer (the guide’s malbec recommendation for purchase — the guide considers the Quimera — the blend — the most underpriced wine produced in Mendoza today — this position has not changed in 8 years).

• Malbec arrived from France 1853 · Michel Aimé Pouget · found its conditions
• 40% more UV at 900m · “the vine’s suntan is the tannin in the glass”
• Zuccardi Valle de Uco · guide’s preferred · soil classification project · Andes view
• Achaval Ferrer Quimera · most underpriced wine in Mendoza · guide hasn’t changed position in 8 years
• Allocate 4 days not 2 · visitors who allocate 2 ask why at departure

Ushuaia (the southernmost city on Earth — at 54°S latitude on the Beagle Channel — the channel named for HMS Beagle, the ship that carried Charles Darwin through these waters in 1832 and 1833 — Darwin’s observations of the Yamana indigenous people of Tierra del Fuego in the Beagle Channel becoming part of his developing theory of natural selection — the guide notes the connection without declaring it comfortable — the Yamana were effectively destroyed by the contact with European missionaries that followed Darwin’s observation of them) is the gateway city for Argentine Patagonia’s southernmost experiences and for Antarctica expeditions. The Tierra del Fuego National Park (the park that begins at the edge of Ushuaia and extends south and west into the Andes — the southernmost national park in the world — the Lapataia Bay trail (the 3km walk to the endpoint of Ruta Nacional 3 — the Argentine national highway that begins in Buenos Aires 3,079km to the north — the guide’s note: “this is the end of the road in the literal sense — the sign at Lapataia Bay says 12,500km to Alaska — the group photographs the sign — the guide has photographed the group at this sign 200 times — the sign has not moved”)). The Beagle Channel boat trip (the half-day navigation of the Beagle Channel — the sea lion colonies on the rocky outcrops (the South American sea lion (Otaria flavescens) — the guide distinguishes from the Patagonian fur seal (Arctocephalus australis) — both visible on the rock colonies — the guide can identify the species from the boat at 50m and considers identification a minimum courtesy to the animal), the Magellanic penguin colony on Isla de los Pájaros, the Les Eclaireurs Lighthouse (the lighthouse consistently misidentified as the “Lighthouse at the End of the World” — Julio Verne’s lighthouse is actually at San Juan de Salvamento 200km to the east — the guide makes this correction without expecting it to affect the photograph)). The Antarctica connection (Ushuaia is the primary departure port for Antarctic Peninsula expeditions — the 2-day Drake Passage crossing — the Cooee Tours Antarctic programme departs from the Ushuaia port — the guide recommends adding a 10–14 day Antarctic expedition as the logical extension of the Patagonia itinerary for visitors with the available time and budget).

• Southernmost city on Earth · 54°S · Beagle Channel · Darwin’s 1832 route
• Ruta 3 end · 3,079km from Buenos Aires · the sign · guide has photographed 200 groups here
• Beagle Channel boat · sea lions · penguins · the Les Eclaireurs lighthouse (not Verne’s)
• Antarctica departure port · Drake Passage 2 days · Cooee Tours Antarctic expeditions
• Guide corrects the lighthouse identification without expecting it to affect the photograph

Península Valdés (the UNESCO World Heritage Site on the Atlantic coast of Argentine Patagonia — accessible from Puerto Madryn — 1 hour by road) is the wildlife destination within the Argentina circuit that specifically rewards the September–December timing — the window when the southern right whale (Eubalaena australis) calves and nurses in the sheltered waters of the Golfo Nuevo and Golfo San José bays that the peninsula encloses. The southern right whale (the whale — Eubalaena australis — the same whale hunted to near-extinction in the Southern Ocean whaling era (the name “right whale” derived from whalers’ designation of it as the “right” whale to hunt: slow-moving, buoyant, and rich in oil — the guide presents this etymology directly) — now recovering — the Península Valdés population (approximately 2,000 individuals using the Golfo Nuevo as a nursery) is the largest single gathering of southern right whales in the world — the whale-watching boats at Puerto Piramides navigate to within 30m of nursing mothers and calves — the guide’s briefing: “the whale is curious — the calf is very curious — the guide has had a whale surface within 5m of the boat on 6 occasions — on 5 of those occasions the guide was calm — the sixth was different”). The orca (killer whale) beaching (the specific orca behaviour unique to Península Valdés — the deliberate beaching of orcas on the shore of Punta Norte at the northern tip of the peninsula to hunt sea lion pups — one of only two locations in the world where this hunting technique is observed (the other being the Crozet Islands in the sub-Antarctic) — the behaviour observable January–March from the Punta Norte lookout — the guide books the Punta Norte dawn position (5:30am — the group is not told the time until the night before — the guide’s position: “the information about the 5:30am departure time is better received at 8pm the night before than at the moment of booking”)). Also at Península Valdés: the Magellanic penguin colony at Punta Tombo (the largest Magellanic penguin colony on the mainland — approximately 1 million penguins — visible September–April — the guide walks through the colony on the marked path — the penguins have the right of way on the path — the guide enforces this).

• Southern right whale · 2,000 individuals at Golfo Nuevo · largest gathering in the world
• Whale within 5m of boat · on 6 occasions · 5 times calm · the guide does not describe the sixth
• Orca beaching · Punta Norte · hunt sea lion pups · 5:30am · group told the night before
• Punta Tombo penguin colony · 1 million Magellanic penguins · penguin has right of way on path
• Best Sep–Dec · right whale calving season · UNESCO World Heritage
