The Tweed & the Caldera
Inland from the surf, a vast rainforest caldera left by an ancient volcano, centred on sacred Wollumbin (Mount Warning) — with waterfalls, art and the rail trail.
The Tweed & the Caldera
Inland from the coast, the land rises into the Tweed Caldera — one of the world’s largest erosion calderas, a vast rainforest bowl left by an ancient volcano. At its centre stands Wollumbin (Mount Warning), sacred to the Bundjalung people, ringed by waterfalls, World Heritage rainforest and the towns of the Tweed. Here’s how to explore it respectfully.
What to See & Do
The Tweed Caldera
A vast rainforest bowl left by an ancient volcano, ringed by ranges.
Wollumbin
A sacred Bundjalung site — the summit is closed; take in the peak from lookouts.
Nightcap & Minyon Falls
Gondwana rainforest and Minyon Falls, plunging around 100 m.
Murwillumbah & Rail Trail
The caldera’s gateway town, its art gallery and the rail trail.
Honouring Wollumbin
Wollumbin (Mount Warning) is a sacred men’s site for the Bundjalung people, and the summit walk is permanently closed. Please don’t attempt to climb it. The mountain is at its most striking from a distance in any case — take in its profile from the caldera-rim lookouts and the surrounding valleys, and let the closure be part of how you experience this Country.
Exploring the Tweed
- View Wollumbin from lookouts and valleys — the summit is closed and sacred; honour it
- Chase waterfalls at Minyon Falls and Nightcap National Park
- Ride or walk the Northern Rivers Rail Trail from Murwillumbah
- Bring the family to Tropical Fruit World
- See the Tweed Regional Gallery & Margaret Olley Art Centre (check current details)
- Let us drive on a hinterland & waterfalls tour
The Tweed & the Caldera — FAQ
What is the Tweed Caldera?
It is one of the world’s largest erosion calderas — the deeply eroded remains of an ancient shield volcano, its ring of ranges cloaked in World Heritage-listed Gondwana rainforest and centred on Wollumbin (Mount Warning).
Can you climb Wollumbin (Mount Warning)?
No. The summit walk is permanently closed, and the mountain is a sacred men’s site for the Bundjalung people. Please honour the closure and enjoy Wollumbin respectfully from lookouts around the caldera rather than attempting to reach the top.
Where can you see waterfalls?
Nightcap National Park has the region’s finest — Minyon Falls drops around 100 m over a rainforest escarpment, with Protesters Falls nearby. See Minyon Falls and Nightcap National Park.
What is there to do around Murwillumbah?
Murwillumbah is the gateway to the caldera and home to the Tweed Regional Gallery & Margaret Olley Art Centre. It anchors the Northern Rivers Rail Trail, and Tropical Fruit World is nearby. Hours change — check current details.
Is the Tweed good for families?
Yes — ride or walk a stretch of the rail trail, meet exotic fruit at Tropical Fruit World, and take in the caldera views. For a guided day, see our hinterland & waterfalls tour.
