Walking inside a glacier is one of those things you can only really do in a handful of places on Earth, and Iceland makes it surprisingly easy. Whether you want to step into a glowing blue ice cave, hike across a glacier tongue with crampons on your boots, or race across the ice on a snowmobile, there is a tour that fits. This guide explains the different options, when each one runs, and what to know before you book.
Ice Cave or Glacier Hike: What’s the Difference?
People often use the two words interchangeably, but they are different experiences:
- Ice cave tours take you inside a glacier, through passages carved by meltwater, to see the translucent blue walls up close. Most are short, gentle walks once you reach the cave entrance.
- Glacier hikes take place on top of the ice. You wear crampons, follow a guide across the glacier surface, and see crevasses, ridges, meltwater channels and views down the valley.
- Glacier adventures add a vehicle or an activity: a snowmobile ride, a Monster Truck up a glacier, kayaking among icebergs, or ice climbing.
When Can You Visit an Ice Cave in Iceland?
This is the question we get most, and the answer depends on which cave:
- Natural ice caves in Vatnajökull (reached from Jökulsárlón and Skaftafell) are a cold-season experience. They form when meltwater carves passages through the ice, and they can only be visited when conditions are cold and stable enough to be safe. The tours typically run from October to April, and the exact dates depend on the glacier. The caves change every year, so no two seasons look the same, and your guide decides on the day which cave is safe to visit.
- The Katla ice cave in Mýrdalsjökull, reached from Vík on the South Coast, is available year-round, which makes it the go-to option if you are visiting outside the cold season.
- Langjökull, Iceland’s second-largest glacier, can be visited all year on the Into the Glacier tours from Húsafell and from Reykjavík. If you would rather see a natural ice cave on Langjökull, the tour from Gullfoss runs from November to mid-April.
If you are travelling in the colder months and want the most classic “crystal blue” look, a Vatnajökull ice cave is hard to beat. In summer, choose Katla or Into the Glacier on Langjökull.
Ice Cave Tours by Region
Vatnajökull: Jökulsárlón and Skaftafell (autumn to spring)
Vatnajökull is Europe’s largest glacier by volume, and its southern outlets are where the natural ice caves form each cold season. Tours depart from the Jökulsárlón area and from Skaftafell, last roughly 2.5 to 4 hours, and are rated easy. You travel to the glacier by Super Jeep or 4×4 and then walk to the cave with your guide. Options include the Crystal Ice Cave tour from Jökulsárlón and the Skaftafell Ice Cave tour with a glacier hike.
Katla Ice Cave, Vík (year-round)
Beneath Mýrdalsjökull, the glacier that covers the Katla volcano, the Katla ice cave is reached by Super Jeep from Vík. It is the most flexible option for timing, and it pairs naturally with a South Coast day. Choose between the quick Fast Track Ice Cave Tour from Vík (2 to 3 hours, suitable for ages 6 and up), the 4-hour Katla Ice Cave drone tour, a private Katla ice cave tour for your own group, or a full-day South Coast and Katla Ice Cave Super Jeep tour from Reykjavík.
Langjökull, Gullfoss and Húsafell
If you are travelling the Golden Circle, Langjökull is the easiest glacier to add. Tours take you up onto the ice in a specialised glacier vehicle. Try the Langjökull ice cave tour from Gullfoss by Monster Truck, Into the Glacier from Húsafell, or a full day combining it with the Golden Circle: Golden Circle & Ice Cave Tour from Reykjavík or Into the Glacier from Reykjavík. These are rated very easy, so they suit families and anyone who would rather not hike. Note that some of these tours are seasonal, so check the dates on each tour page.
Glacier Hikes: Where to Walk on the Ice
You do not need to visit in winter to walk on a glacier. Most glacier hikes run all year and are some of the most rewarding half-day outings in Iceland.
- Sólheimajökull (South Coast). A little over two hours by road from Reykjavík and just off Route 1, this glacier tongue is the most accessible in the country. Options range from the Glacier Discovery hike to a longer glacier hike with ice climbing, plus Glacier Exploration (a longer, more demanding hike, April to September) for those who want more time on the ice. In summer you can also try glacier kayaking among the icebergs (June to October).
- Skaftafell (Vatnajökull National Park). The Blue Ice Experience hike in Skaftafell takes you across a glacier in one of Iceland’s most dramatic national park settings.
- Langjökull and Vatnajökull by snowmobile. For a faster way across the ice, try the Langjökull snowmobile tour from Gullfoss or the Vatnajökull snowmobile tour from the southeast (seasonal, so check availability).

What to Wear and Bring
Weather on a glacier can be colder and windier than where you started, even in summer. Dress in layers:
- Warm base layers and a fleece or wool mid-layer
- A waterproof, windproof jacket and trousers
- Sturdy hiking boots with ankle support (crampons need a firm sole; trainers are not suitable)
- Warm hat, gloves, and sunglasses for the glare off the ice
- A small backpack with water and a snack
Specialised gear such as helmets and crampons is provided by the tour operator on guided glacier trips, but each tour page lists exactly what is included, so check before you go.
Safety: Why You Should Never Visit Ice Caves on Your Own
Glaciers are living, moving things. Ice caves can collapse, meltwater can undercut ledges, and crevasses are often hidden beneath snow. For that reason, entering an ice cave or going out on a glacier without a certified guide is genuinely dangerous. Guided tours check conditions each day, choose a safe cave or route, and will change or cancel the plan if conditions are not right. If your tour is rescheduled for safety reasons, that is the system working as intended.
Frequently Asked Questions
Can I see an ice cave in summer?
Yes, but only certain ones. The natural caves in Vatnajökull are a cold-season experience, while the Katla ice cave from Vík and the Into the Glacier tours on Langjökull run all year.
What is the best month for an ice cave tour?
For natural Vatnajökull ice caves, January and February usually have the most stable conditions. For other times of year, book Katla or Into the Glacier.
Do I need hiking experience?
No. Most ice cave tours are rated easy or very easy, and most glacier hikes are suitable for beginners with normal fitness, although longer ones such as Glacier Exploration are more demanding. Your guide sets the pace and shows you how to use crampons.
Are ice cave tours suitable for children?
Many are, but minimum ages vary by tour, from 4 on the Langjökull Monster Truck tours to 12 or older on the more active hikes. The Langjökull tours are rated very easy. Always check the minimum age and difficulty on the tour page before booking.
Will my tour run if the weather is bad?
Tours depend on daily conditions. If a tour cannot run safely, the operator will let you know, and the cancellation terms on each tour page explain what happens next.
Can I combine a glacier with other sights?
Absolutely. A glacier or ice cave pairs well with the South Coast waterfalls and black sand beach, the Golden Circle, or the Jökulsárlón glacier lagoon, and several of our tours bundle them already.
