Caving · Reykjavik
How to choose
Caving near Reykjavik runs from 59 € to 285 € with durations ranging from 1 hour to a full day. Budget options (59 € to 101 €) cover lava tube exploration at Raufarhólshellir or Leiðarendi, all rated accessible to everyone and ideal for first-timers. Mid-range picks (around 207 €) combine horseback riding with lava caving in a 7-hour day. Premium tours (252 € to 285 €) push the experience further: 11 hours inside Katla Volcano's ice cave on Mýrdalsjökull glacier, a full-day snorkeling and caving combo, or a 9 to 10-hour glacier cave expedition inside Langjökull in Þingvellir National Park. One tour (index 0) specifies "Occasionally sporty" as the physical level, meaning expect some crawling and uneven terrain. Your decision comes down to one question: do you want raw lava rock under your feet or glacial ice above your head?

Practical info
Equipment
Helmets and headlamps are standard kit on lava tube tours, typically provided by the operator. Wear warm, layered clothing and sturdy closed-toe shoes with grip since lava rock surfaces are uneven, and ice cave tours inside Mýrdalsjökull or Langjökull demand an extra thermal layer regardless of the season.
Getting there
Most tours include pick-up directly from your accommodation in Reykjavik, while self-drive participants can meet operators at designated GPS coordinates (e.g., N.63º 56.407 / W. 021º 23.742 for Raufarhólshellir) or at Síðumúla 13, Reykjavik.
