There are two iconic and naturally formed ice caves in Iceland that have taken social media by storm. The pictures and videos have people from all over the world flocking to Iceland during winter to winter their beauty.

Why are Katla Ice Cave and Crystal Ice Cave Different?

Katla Ice Cave and The Crystal Ice Cave are relatively close to each other (2.5 hour drive apart) but they provide much different experiences. In this episode I will give a little insight about when to see naturally forming ice caves in Iceland (meaning ones that are not man-made).

I will also share the temperature inside of an ice cave, how to dress for an ice cave tour, the pros and cons of each ice cave tour based on my personal experience. I thought it would also be helpful to share the cost as of January 2025 for each along with what will be included, and which one I preferred after taking both tours.

Please know that both are absolutely stunning and worth checking out. Time in the country, daylight hours, the season, and cost play a huge factor for most people so I did my best to take that into account.

When is the best time to See Naturally Formed Ice Caves in Iceland (Katla Ice Cave & Crystal Ice Cave)?

In terms of stability, safety, and stunning colors of the ice caves, winter is the best time to explore naturally formed ice caves. The ice cave season is usually from late November to March.

The time frame can change based on weather conditions for that year. Sometimes we have a cooler or warmer months, so the season might vary slightly from year to year for naturally formed ice caves.

I keep saying naturally formed because there are man-made ice caves here that pretty much keep the same shape and access throughout the year. I did an episode on the largest man-made Ice Tunnel in the world in 2024 called 7 Fascinating Facts I Learned Inside Iceland‘s Langjökull Glacier. Feel free to check that out if you are looking to explore a stable ice cave in a glacier anytime of year. As mentioned before, you can use my code Iceland10 to save 10% with Arctic Adventures for that experience too.

What is the Temperature inside of an Ice Cave?

The temperature inside ice caves typically hovers around 0°C (32°F) and remains relatively constant regardless of external weather conditions. That often shocks people because the expectation is that naturally formed ice caves will be extremely cold but during winter they can often be warmer than outside the cave.

What to wear on an Ice Cave Tour?

Thermal Base Layer: Wear a moisture-wicking base layer made of materials like merino wool or synthetic fabrics to keep you dry and warm.
Insulating Mid-Layer: Add a fleece or insulated jacket to provide additional warmth.
Waterproof Outer Layer: Use a windproof and waterproof jacket and pants to protect against moisture and wind.
Warm Hat and Gloves: Bring a hat that covers your ears and gloves to keep your hands warm.
Water-Resistant Footwear: Choose sturdy, water-resistant boots with good traction to navigate slippery surfaces.

Additional Tips:

Dress in Layers: This allows you to adjust your clothing to maintain comfort throughout the tour.
Safety Gear: Some tour operators provide crampons, helmets, and headlights, so check with your provider for any specific recommendations or equipment they may supply.

Katla Ice Cave Tour

Katla Ice Cave Tour is located in Katla Volcano and glacier, which is near the town of Vík in South Iceland. Vík is about a 2 hour and 30 minute drive straight from Reykjavík.

The duration of the tour is 3 hours, if you meet at the meetup point in Reykjavik or 11 hours if you are transported from the city.
