You step out where steam threads the cold air and the ground hisses—Seltún’s fumaroles puncture the skyline, sulfur-streaked soils glowing against black lava. The first hour carries you across geothermal plates and brittle ground, the landscape alternating between hot vents that dare you to approach and moss-carpeted ridges that cushion each footfall.

You step out where steam threads the cold air and the ground hisses—Seltún’s fumaroles puncture the skyline, sulfur-streaked soils glowing against black lava. The first hour carries you across geothermal plates and brittle ground, the landscape alternating between hot vents that dare you to approach and moss-carpeted ridges that cushion each footfall.
This route on the Reykjanes Peninsula threads together Iceland’s recent geological story: rifting along the Mid-Atlantic Ridge, young basalt flows, and kettled lakes formed in depressions where magma once boiled. Humans here have long measured their fortunes against the sea and the earth—fishing villages on the coast, and folklore about hidden fires beneath the hills. Today the area is managed for safety and conservation; boardwalks and marked routes protect fragile vegetation.
Expect 15 km (9.3 mi) with roughly 560 m (1,840 ft) of elevation gain over variable, mostly singletrack and rough path that takes about 7 hours at a moderate pace. Your International Mountain Leader will demonstrate compass and altimeter use and point out geothermal features and navigational clues as you go.
Practical notes: pack a waterproof shell, sturdy boots, warm layers, and extra water; weather flips quickly here. Meeting is at the designated lot—bring cash or card for the small parking ticket (~€5). Groups are capped (up to 12), participants must be 16+, and a moderate fitness level is required. Read route briefings, stay on trails to protect delicate moss, and allow for slower sections where terrain steepens—this day trek rewards patience with sweeping lake views and raw, volcanic scenery.

This listing meets roughly 40 minutes from Reykjavik; check booking details for pickup options—some departures require meeting at the designated starting point.
Participants must be 16+; not recommended for those with significant back, heart, or pregnancy-related restrictions due to terrain and physical demands.
The Reykjanes Peninsula is geologically young—shaped by rifting along the Mid‑Atlantic Ridge and frequent volcanic activity; local communities historically relied on fishing and geothermal resources.
Vegetation here is fragile—stay on marked routes, pack out waste, and avoid disturbing geothermal features to protect regrowth and preserve thermal areas.
Hikers of Iceland operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
