Katla Ice Cave

Kötluhellir

South Coast

Kötluhellir sits inside the Kötlujökull outlet glacier, a lobe of Mýrdalsjökull (Iceland's fourth-largest ice cap) that overlies the active Katla volcano. What sets it apart from Iceland's other ice caves is its combination of colours: the walls and ceiling display deep blue glacial ice threaded with thick bands of black volcanic ash deposited by past Katla eruptions. The result is a layered geological record that looks unlike any other cave in the country. Unlike most natural ice caves in Iceland, which are only safe to enter from November to March, Kötluhellir is accessible throughout the year because geothermal heat from the volcano below moderates melting patterns and keeps the structure relatively stable. All visits require a guided super-jeep tour departing from Vík í Mýrdal. Tour operators pick up at the bus car park near the Icewear/Krónan building in Vík, then drive roughly 30–45 minutes north across black-sand plains and unbridged river crossings to the glacier edge — terrain that is impossible in a standard rental car. At the glacier, guides fit visitors with crampons, helmets, and headlamps for a 1–2 km walk across uneven ice to the cave entrance. The total excursion runs around three hours; one hour is typically spent inside the cave itself. Prices start from around 23,900 ISK per person for the standard Vík-based tour, with private and buggy options at higher cost. Minimum age is 8–12 years depending on the operator. Because this is an active volcanic zone, tours are monitored and can be cancelled on short notice due to volcanic or weather conditions. Booking in advance, especially in summer, is strongly advised.
