About this activity

Combine Iceland's most dramatic geological spectacle with geothermal relaxation: hike to the active Fagradalsfjall volcano on the Reykjanes Peninsula—site of the first eruption in 800 years—then unwind in the milky-blue waters of the Blue Lagoon. A 9-hour full-day experience balancing adventure with spa comfort.

Volcanic Eruption in Geldingadalur, Fagradalsfjall

This first eruption in the Reykjanes Peninsula in about 800 years provides a unique opportunity to study the geologic mysteries of the region and is open for all to enjoy! After being shaken by months of increasingly disruptive earthquakes, including thousands in the past weeks, Iceland’s Reykjanes Peninsula is finally experiencing the volcanic eruption that many geologists suspected was on its way. 

After an exciting hike to the Volcano we end the day at the Blue Lagoon. Immerse yourself in the milky-blue geothermal seawaters. Included in the comfort package is entrance to the Blue Lagoon, silica mud mask, use of a towel and 1st drink of your choice.

Reykjavik Excursions offers a guided tour to the volcanic eruption in Geldingadalur, known as Fagradalsfjall Volcano. The driver and guide will take the group to the start of the hiking route towards the volcano in Geldingadalur, where the group will hike towards the volcano. The hike will take approximately 1.5 hours each way, please note that this is an estimated time. The sites around the volcano are always changing due to freely flowing lava and the hiking time can change. *

Don´t miss out on this once-in-a-lifetime experience and witness the raw power of lava pouring out of the surface of the earth.


Please wear hiking shoes and bring crampons as conditions can be slippery during winter.
