Walk across freshly formed lava fields with a professional geologist and learn the science behind Iceland’s 2021 eruption. This small-group hike from Reykjavík combines hands-on geology with a rugged, exposed walk to a crater viewpoint.
More ways to explore the area's outdoor wonders
You step off the bus into a landscape that still smells faintly of sulfur and iron — a black expanse of glassy, fractured lava stretching toward a low volcanic cone. Wind pushes across the Reykjanes Peninsula and, under a sky that can flip from clear to stormy in an hour, your guide — a professional geologist — points out fresh crust, blocky ʻaʻā flow textures, and the hairline seams where tectonic plates meet.
Difficulty

Duration
4–6 hours
Fitness Level
Moderate fitness — able to hike 3–5 miles over uneven terrain with some elevation and sustained exposure to wind and cold.
Wildlife
History
The Reykjanes Peninsula is an active volcanic zone on the Mid-Atlantic Ridge; the 2021 Fagradalsfjall eruption created new lava fields and altered local routes.
Conservation
The fresh lava fields are fragile—avoid kicking or walking on early moss and lichen; follow guide instructions to limit erosion and protect slow-recovering habitats.
Reserve your spot on the Small Group Volcano Hike with a Professional Geologist today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Footwear first
Stiff, ankle-supporting hiking boots are essential — lava rock is jagged and unforgiving on soft soles.
Watch the weather
Wind, rain, and fog can arrive quickly on the peninsula; bring a waterproof shell and check the forecast before you leave.
Expect uneven terrain
Use trekking poles if you rely on extra stability; the trail crosses broken, sharp basalt and occasional scree.
Respect safety zones
Stay with the guide and behind any cordons — newly cooled lava can be unstable and hot pockets are possible.
Sturdy hiking boots
Support and aggressive tread protect ankles and provide grip on sharp basalt.
Windproof, waterproof shell
Keeps you warm and dry in rapidly changing Icelandic weather.

Crampons or microspikes
Useful on icy patches or early/late-season snow on the lava fields.
