Katla Ice Cave Tour Summer Guide
Most Icelandic ice caves close for the summer. Katla does not: the same tours run in July as in January — with long light, easy roads and a darker, wetter cave.
Quick answer
Yes — the Katla ice cave is open in summer, unlike most Icelandic ice caves, which run mostly from November to March. In June–August expect more visible black ash, meltwater dripping from the ceiling and a slightly darker cave, but also easy roads and about 21 hours of light. Tours from Vík start at €158.

Key takeaways
- Open every month of the year

- Every summer departure runs in daylight
- July in Vík averages 9–14 °C
- Same tours and prices; some start times move
Summer or winter: what changes
Katla is one of the few ice caves in Iceland you can visit in summer: it sits in a thick tongue of the Kötlujökull glacier that holds its shape when other caves become unsafe. None of the 15 tours we track is sold as winter-only.
The cave itself changes. In winter the ice is at its bluest and the cave can feel brighter; in summer the black ash layers stand out more, water drips from the ceiling and it can feel darker inside. Guides choose the safest section on the day.
Outside, summer wins on comfort: mild air, easy roads and long evenings. Winter brings the bluest ice but short days, snow on the approach and a real chance of storms.

When the light is: departures through the day
The same departures from Vík in late June and late December, and whether each one runs in daylight.
Every departure is in daylight, from the first to the last.
Vík departures, each about 3 hours
Only the 11:30 and 12:30 departures run fully in daylight.
Vík departures, each about 3 hours
In summer you can take any departure. The first tours leave Vík at 8:30 and the last at 16:30, and in late June the sun is up from about 3:00 until midnight, so the whole three-hour trip runs in daylight.
Light still shapes the choice. The first or last slot of the day is usually calmer in the cave, and from March to October Gravel Travel’s cheaper off-peak departures move to exactly those times: 8:30 and 16:00, for €158 — see our review of the small-group tour.

What to wear in summer
Summer is not dry inside the cave. Meltwater drips from the ceiling, so a waterproof jacket and waterproof trousers matter more than in winter. July in Vík averages 9–14 °C and 13 days of rain, so bring a warm layer too.
Hiking boots are asked for by 10 of the 15 tours, summer or not: the crampons strap onto them. Gloves help on the ice even in July, and a thin hat fits under the helmet.

Katla or the Vatnajökull caves in summer?
In summer the choice is made for you: Katla is open, while the crystal caves of Vatnajökull run mostly from November to March. Katla is also much closer to Reykjavík — day trips with pickup reach it and the south-coast waterfalls in one day.
In winter the comparison is real: Vatnajökull offers clearer blue ice, Katla the black ash, a shorter trip and a cave you can reach in half a day from Vík.

Katla ice cave tour in summer: questions
Is the Katla ice cave open in summer?
Yes, all year. It is one of the few Icelandic ice caves you can visit between May and September.
Is the Katla ice cave tour in summer worth it?
Yes, if you are in Iceland in summer it is the most accessible ice cave you can see. The ice shows more black ash and is wetter inside than in winter.
Is it cold inside in summer?
Yes — it is a cave in a glacier. Bring a warm layer, gloves and waterproofs, even when Vík is 14 °C.
Do summer tours cost more?
Not on the tours we track: prices are set by slot and operator, not by season. Gravel Travel’s off-peak slots cost €158 all year, its peak slots €193.
What time is best in summer?
The first or last departure of the day — 8:30 or around 16:00 on the Vík tours — for a quieter cave and softer light.
Can I see the midnight sun on the tour?
The tours run in the day, not at night. In late June the sun is up from about 3:00 until midnight, so you have light for the whole trip either way.
