Vatnshellir Lava Cave

Local name: Vatnshellir

The lava tube formed roughly 8,000 years ago, and the tour ends with the whole group switching off their headlamps in the dark.

Vatnshellir Lava Cave is a lava tube on the Snæfellsnes Peninsula in West Iceland, inside Snæfellsjökull National Park. The tube formed about 8,000 years ago. It is entered on a guided tour only, down a metal spiral staircase that drops more than 30 metres below the surface. Helmets and headlamps are provided. The route runs through several lava chambers on uneven, damp ground, with no crawling or rope work. Tours take about 45 minutes and start from a small hut beside Road 574.

What makes it special

The tour goes straight down. A metal, silo-style spiral staircase drops more than 30 metres from the surface into a lava tube that formed about 8,000 years ago. Below it the passage opens into chambers big enough to stand and walk in. Mineral colours run through the walls, and the floor is craggy and wet. There is no crawling, no rope work and no mud — it is a walking tour on uneven ground, with a helmet and headlamp handed out at the start. The set piece comes when the guide has everyone switch off their lamps. No daylight reaches this far in, so the darkness is complete, and so is the silence.

Good to know

Guided tours only. You cannot walk into the cave on your own. Helmets and headlamps are handed out at the start.
No toilets. There are none at the cave and none in the car park. Sort that out before you set off.
Dress for cold and wet. The cave stays chilly whatever the weather above, and the entrance is slippery. Wear sturdy shoes.
Two metal staircases. The descent and the climb back are on open metal stairs, which matters if you are uneasy with heights.
Tours meet in a small heated hut by the car park, where the cave's exploration history is set out on the walls.

Getting there

There is no bus to the cave and no stop within 5 km, so everyone arrives by car. The site sits directly on Road 574 inside Snæfellsjökull National Park, on the Snæfellsnes Peninsula in West Iceland. The car park is right off the main road, about 100 metres from the small heated hut where tours meet. Walk that far and the rest of the approach is vertical: the tour starts with the staircase down into the lava tube.

Best time to visit

Better: a wet or windy day, at any point during opening hours.

Avoid: arriving close to closing time, since a tour has to finish before the doors shut.

No daylight reaches the cave and conditions underground stay much the same all year, so the weather on the surface changes nothing about what you see. On the Snæfellsnes Peninsula, where most of the sights are outdoors, that makes this one of the few plans that survives a storm.
