Vatnajokull Ice Cave Guided Tour from Jokulsarlon

Jokulsarlon glacier lagoon

Your ice cave tour begins at Jokulsarlon, the famous glacier lagoon on the south-east coast of Iceland. The lagoon only began to form in the 1930s, when the tongue of Breidamerkurjokull started to retreat from the sea, and it has grown quickly ever since. Today it is the deepest lake in Iceland, at roughly 280 metres, and is filled with icebergs that have broken off the glacier front, some glassy blue, some striped with ash. Seals often swim among them.

A short channel carries the ice under the bridge of Route 1 to the sea, where pieces wash up on the black sand of Diamond Beach just across the road. Come a little before your meeting time to walk the shore of the lagoon: it is one of the most photographed places in the country, and the light on the icebergs changes by the hour.

Vatnajokull and its national park

Vatnajokull is the largest ice cap in Iceland, covering about 7,700 square kilometres, close to a tenth of the country, and reaching a thickness of nearly a kilometre in places. Several active volcanoes lie hidden beneath it, among them Grimsvotn and Bardarbunga, and their eruptions have left layers of ash inside the ice for centuries. Dozens of outlet glaciers flow down from the ice cap like frozen rivers towards the lowlands.

Vatnajokull National Park, founded in 2008, protects the ice cap and much of the land around it, and was listed as a UNESCO World Heritage Site in 2019 for its unique mix of fire and ice. Breidamerkurjokull, where the ice caves form, is one of the outlet glaciers that feed Jokulsarlon. A Vatnajokull tour is the easiest way to see this landscape safely, with guides who know the ice.

Super jeep ride across Breidamerkursandur

From the lagoon, the group climbs into a super jeep, a high-clearance four-wheel-drive vehicle with oversized tyres, built for the rough tracks of the glacier forefield. The drive crosses Breidamerkursandur, a wide plain of black sand and gravel washed out by meltwater rivers, and passes old moraines, the ridges of stones that mark where the glacier front stood in earlier centuries.

The ride itself is part of the adventure, bumping over tracks that ordinary cars cannot use, with the white wall of the glacier growing larger ahead. Near the ice the jeep parks and you continue on foot for a short walk over uneven ground to the cave entrance. Your guide fits the helmet and crampons and explains how to move safely before you go in.

Inside the ice cave

Natural ice caves in Vatnajokull are carved by meltwater that runs through and under the glacier in summer. When the cold season arrives and the rivers freeze, guides check which caves are stable enough to enter. Because the glacier moves and melts, every cave is different each year, and no two visits are alike. The ice glows blue because dense, old glacier ice absorbs red light and lets blue pass through, while bubbles and dark ash bands add texture to the walls.

Is the Vatnajokull ice cave worth visiting? For many travellers it is the highlight of a trip to Iceland: standing inside a tunnel of ice that formed from snow fallen centuries ago is unforgettable. Your guide explains how the cave formed, points out the best photo spots and keeps the group within safe areas.

How to get to Jokulsarlon and the best time to visit

Jokulsarlon lies beside Route 1 on the south coast, about four and a half to five hours by car east of Reykjavik, roughly an hour west of the town of Hofn and under an hour east of Skaftafell. Most visitors spend the night nearby or combine the ice cave with a self-drive trip along the south coast. There is a large parking area with toilets and a cafe at the lagoon.

The best time to visit the Vatnajokull ice caves is in the cold months, roughly from November to March, when frozen meltwater makes the caves stable. Morning departures give soft light, while the mid-afternoon slots suit those driving from further away. Winter also brings the chance of northern lights over the lagoon in the evening.
