Katla Ice Cave vs. Vatnajökull: Which One Is Best for Your Iceland Trip?
Katla Ice Cave or Vatnajökull? The Katla Ice Cave is accessible all year round, located just 2.5 hours from Reykjavík (187 km / 116 miles) departing directly from the Katlatrack office in Vík í Mýrdal, and features dramatic blue ice combined with layers of black volcanic ash from the 1918 eruption. Conversely, Vatnajökull caves open primarily in winter (November to March), sit over 4.5 hours from Reykjavík (370 km / 230 miles) near Jökulsárlón, and offer transparent crystal blue ice, but require significantly longer travel itineraries.
If you are planning a road trip along the South Coast of Iceland and want to explore an authentic ice cave beneath a real glacier, the first big decision you will face is: should you visit the Katla ice cave (Mýrdalsjökull glacier) or the caves in Vatnajökull?
While both experiences are breathtaking, the logistics, year-round availability, driving time from Reykjavík, and type of ice vary radically between the two locations.

Katla Ice Cave Tour Options with Katlatrack from Vík
The Katla ice cave is located in the Kötlujökull glacier tongue, an outlet of Mýrdalsjökull (Iceland’s fourth-largest ice cap), beneath which lies the famous active Katla volcano.
To fit different travel paces and itineraries, at Katlatrack we offer three distinct ways to explore this unique environment:
- Katla Ice Cave Fasttrack Tour (3 hours): Our undisputed bestseller. Designed to optimize your travel time, it includes the round-trip Super Jeep ride from Vík, the hike to the ice cave, and guided exploration inside. It is the ideal choice if you have a tight schedule on the South Coast.
- Katla Ice Cave Extended Tour (4 hours): The perfect option for photography enthusiasts and travelers seeking a deeper immersion. This 4-hour tour includes extra scenic stops along the Super Jeep drive and allows you to spend more time exploring on top of the glacier and inside the cave.
- Katla Ice Cave Private Tour (Exclusive): A 100% customized experience where the Super Jeep and an expert local guide are dedicated solely to you and your group. It allows you to tailor the hiking pace, take bespoke photo stops, and enjoy the glacier in complete privacy.
What Is a Super Jeep and Why Is It Essential for This Route?
Many travelers ask us why it isn’t possible to reach the glacier in a standard rental car or even a small 4×4 SUV. The answer lies in the vehicle we use: the Super Jeep.
A Super Jeep is a vehicle specifically modified to perform flawlessly in severe weather conditions and handle the extreme terrain we encounter on our tours in South Iceland. These are not ordinary off-road vehicles; they are specialized machines built to tackle demanding natural obstacles.
Key Features of Our Modified Super Jeeps:
-
Built-in Tire Compressor System: Thanks to an onboard air compressor, our guides can manually inflate and deflate the tires while on the move depending on the surface. Deflating the tires increases the footprint to float smoothly over soft snow or volcanic sand, while inflating them optimizes highway driving.
-
River-Crossing Capabilities: They are raised and equipped to ford mountain rivers safely without engine flooding or traction loss.
-
Giant All-Terrain Tires: Their specialized tires are engineered to grip securely on all surfaces: snow, mud, water, loose gravel, or asphalt.
The Glacier Experience: Driving Around Hafursey & Technical Safety
The Super Jeep Journey
All our tours depart from the Katlatrack office in central Vík (Austurvegur 16). From there, we board our modified Super Jeeps. The drive to the base of the glacier takes us along an unpaved mountain track circling the iconic Hafursey mountain, crossing a stunning desert of black volcanic ash and moss-covered lava fields (Mýrdalssandur) where scenes for Star Wars: Rogue One were filmed. Standard rental vehicles (including small 4×4 SUVs) cannot legally or safely drive on this terrain.
The Hike & Technical Gear
Upon reaching the edge of the Kötlujökull glacier, we suit up with mandatory safety equipment provided before starting the hike:
-
Adjustable crampons for solid traction on ice.
-
Certified safety helmets.
-
Headlamps to clearly illuminate the inner chambers of the cave.
The glacier walk and inside exploration are conducted alongside expert local guides who explain the unique geology, how ice walls form, and the history behind Katla’s 1918 eruption.
Can You Visit the Katla Ice Cave in Summer?
Yes. This is the major advantage of the Katla Ice Cave compared to almost all other ice caves in the country. You can visit Katla Ice Cave all year round, even during the summer months.
Traditional ice caves in other glaciers form primarily from meltwater flow during the summer. As temperatures rise between May and September, the internal structure of those caves becomes unstable or floods, forcing tours to close for safety during the warmer months.
Why Katla Remains Open Year-Round
Katla allows safe tour operations 365 days a year due to a combination of volcanic geology and glacier dynamics:
- Insulation by Volcanic Ash: Thick layers of black tephra (ash trapped from the 1918 Katla eruption) embedded inside the ice act as a natural thermal shield that slows down direct melting.
- Non-Retreating Glacier Dynamics (“Dead Glacier”): We commonly describe this area as a “dead glacier.” The glacier is simply melting very slowly over time, but it is not actively retreating or expected to shift abruptly. This stability allows us to maintain safe and accessible ice chambers year-round.
Is It Safe to Visit Independently or Do You Need a Guided Tour?
Visiting a natural ice cave in Iceland independently is both impossible and illegal.
Glaciers are dynamic environments that require specialized equipment and expert knowledge to navigate hazards like hidden crevasses or ice falls.
