Hike to Fagradalsfjall Volcano and Witness the Northern Lights from Reykjavík
An evening journey through erupting lava fields, mossy highlands, and the aurora-lit skies of the Reykjanes Peninsula.
This Fagradalsfjall volcano hike takes you deep into the Geldingadalur Valley to witness one of nature's most powerful forces up close, guided safely by an expert who knows the terrain in all conditions. Afternoon and evening departures are designed specifically to capture the most dramatic light and, weather permitting, the northern lights above the lava fields. The combination of an active volcanic landscape and Iceland's iconic night sky makes this one of the most distinctive tours departing from Reykjavík.
The route covers approximately 8 km with around 300 metres of elevation gain, threading through moss-covered lava fields and volcanic mountains that define the Reykjanes Peninsula. Conditions on the peninsula can shift quickly, and your guide will select the most suitable path to the eruption site on the day of the tour. The terrain is rated moderate, meaning a reasonable level of fitness and proper footwear are recommended before you arrive.
En route, the tour passes Kleifarvatn Lake, a striking geothermal lake sitting in a rift valley along the Mid-Atlantic Ridge, offering expansive views that set the scene before the hike begins. The drive across the Reykjanes Peninsula reveals a landscape shaped almost entirely by volcanic activity, from steaming fumaroles to ancient hardened lava fields. Each stop adds geological context that deepens the experience of standing at the edge of an active eruption.
Evening departures provide the best opportunity to observe both the volcanic glow and potential aurora displays, which are most visible away from city light pollution. The peninsula's remote location ensures dark skies, and your guide will advise on aurora viewing conditions throughout the tour. This dual focus on volcanic and celestial phenomena is what distinguishes this itinerary from standard sightseeing routes.

Itinerary
The tour departs in the afternoon or evening from Reykjavík, heading south toward the Reykjanes Peninsula. Your guide provides an introduction to the volcanic geology of the region as the city gives way to raw lava landscapes.
The first stop brings you to Kleifarvatn Lake, a geothermal lake located along the Mid-Atlantic Ridge. The surrounding terrain offers sweeping views and a first glimpse of the peninsula's volcanic character.
The route continues across the peninsula, passing volcanic craters, steaming vents, and hardened lava fields formed over centuries of eruptions. Your guide explains the geothermal processes that continue to shape this active landscape.
The main hike begins through moss-covered lava fields, climbing approximately 300 metres over around 8 km to reach the eruption site in Geldingadalur Valley. The exact route is chosen on the day based on current volcanic activity and safety conditions.
At the eruption site, you spend time observing the volcanic activity with your guide providing context on the ongoing eruption. As darkness falls, conditions permitting, the northern lights may appear over the lava fields for a remarkable natural spectacle.
The group descends the trail and returns by vehicle to Reykjavík, completing an 11-hour round trip. Your guide remains available throughout the return journey to answer questions and share reflections on the day's experience.
