Lofthellir Ice Cave Iceland: Guided Tour & Visitor Guide

Lofthellir is located about 15 km east of Lake Mývatn in North Iceland, roughly 470 km from Reykjavík via Route 1 (the Ring Road). The nearest village is Reykjahlíð at the northeast corner of Mývatn, which has a supermarket, fuel station, and several accommodation options. Tours depart from the Mývatn area (typically meeting at a designated point near Reykjahlíð) and include a short off-road drive on a rough track followed by a 20-minute hike across the Laxárdalur lava field to the cave entrance. A 4x4 vehicle is needed to reach the trailhead, which is provided as part of the guided tour -- you cannot drive there independently. From Akureyri (North Iceland's largest town, 100 km west on Route 1), the drive to Mývatn takes about 1 hour. Akureyri has a domestic airport with daily flights from Reykjavík. The Mývatn area also offers the Mývatn Nature Baths, Dimmuborgir lava formations, and Námaskarð geothermal area, making it easy to plan a full day or multi-day stay.

Lofthellir can be visited year-round since the ice formations persist in every season, maintaining their frozen state even during July and August. Summer (June to August) offers the easiest access with long daylight hours (up to 21 hours), mild weather (10-15°C) for the lava field hike, and the most frequent tour departures. July is the busiest month -- book at least 2-3 days in advance. May and September provide comfortable conditions with smaller tour groups. Winter visits (November through March) provide a more dramatic experience with snow-covered lava fields, potential northern lights on the drive back, and the ice formations at their most elaborate, but the approach hike can be challenging in snow and darkness. December and January tours operate in complete darkness outside the cave, requiring headlamps for the hike. Tours run year-round but schedules are reduced from October through April, typically to 1-2 departures per day.
