What to Expect
Spiral Staircase Descent
Enter the cave via a modern spiral staircase that takes you 35 meters below the surface into the upper chamber of the lava tube.
Two Cave Levels
Explore both the upper and lower chambers, each with distinct lava formations and geological features from the ancient eruption.
Total Darkness Experience
At one point during the tour, all lights are turned off so visitors can take in the complete silence and darkness of the cave.
Lava Colors & Formations
See mineral deposits on the cave walls in reds, yellows, and greens, along with lava stalactites and flow textures.
Jules Verne Connection
The cave sits beneath Snaefellsjokull glacier, the very volcano Jules Verne used as the gateway to the earth's interior in his novel.
National Park Setting
Vatnshellir is within Snaefellsjokull National Park, surrounded by the coastline, lava fields, and the glacier itself.
Getting There
Vatnshellir is located on the western tip of the Snæfellsnes peninsula, about 200 km from Reykjavík (approximately 2.5 hours by car). From Reykjavík, take Route 1 north to Borgarnes, then Route 54 west around the peninsula. The cave entrance and visitor center are at Purkhólar, well signposted from Route 574 near Hellnar village within Snæfellsjökull National Park. A free parking area at the visitor center has space for about 20 cars and has restroom facilities. The drive is entirely on paved roads. The nearest villages for fuel and services are Hellnar (3 km) and Ólafsvík (about 20 km east on Route 574). Vatnshellir is easily combined with other Snæfellsnes highlights like Kirkjufell mountain (60 km east), Arnarstapi (5 km east), Djúpalónssandur beach (3 km north), and Lóndrangar cliffs (2 km east), all accessible within a day trip around the peninsula.
Best Time to Visit
Vatnshellir is open year-round with tours running daily during summer (every 1-2 hours from June through August) and on a reduced schedule in winter (1-2 tours per day from November through March). July and August are the busiest months, with temperatures of 10-14°C and up to 21 hours of daylight, enough to combine the cave with a full day on Snæfellsnes. May and September have comfortable conditions with smaller tour groups. November through February brings the chance of ice formations inside the cave and snow across the Snæfellsjökull landscape, though daylight drops to 4-6 hours and weather on the exposed peninsula can be harsh. The cave temperature stays around 2-4°C regardless of outdoor weather, so bring warm layers in all seasons. Advance booking is recommended during July and August peak season; off-season tours should also be booked ahead to confirm schedules.
