“This was an incredible day! Giuseppe was a wonderful tour guide. He was so knowledgeable about the volcano, and he explained the different kinds of lava rocks, which we would have walked by of he had not been there. I learned a lot! I really enjoyed having lunch on the cooled lava, even though apparently there is still lava flowing about 35 meters below us. The volcano has fairly regular eruptions, with the next one anticipated for late June. About the hike: The first part of the trail is fairly easy, with dirt and gravel paths. There are some fairly steep switchbacks, but Giuseppe planned breaks along the way to…”

“Breathtaking. Could see solidified lava fields. no fresh red hot lava at the time of our hike but there is still hot air coming out of the rocks below. Lovely experience and good weather. Our hike was about 9km. It felt generally fine to hike without hiking sticks, but some hikers brought their own and felt more comfortable with it. To each his/her own. My guide Hler was very informative and included driving around the ghost town of Grindavík where we could still see effects of the latest eruption. Great reward for ourselves at the blue lagoon after!”

10.Landmannalaugar, Hekla, Sigoldugljufur 4×4 tour with Hiking

★★★★★★★★★★4.5 · 37 reviews · 11 hours (approx.) · from $280

Ride a Super Jeep from Reykjavik into Iceland’s volcanic highlands with a driver-guide, hike around Landmannalaugar, see Hekla and Ljótipollur, and stop at the striking Sigöldugljúfur canyon. Expect about 11 hours, rough roads, changing weather, and a small group of up to 14.

“I was 6months out of my 3rd leg surgery so the hike was a little more challenging, but I was definitely able to do it with effort. The hike isn't flat so you have to be ok to go up and down inclines and through lava hills. You also need to be ok with maybe like 1.5 hours of fast, off-roading. There is also a sense of urgency throughout the day. So it does feel very fast-paced. If all of that sounds ok to you, then it is totally worth it! If you are looking for breathtaking beauty and adventure then this is for you!!!! I saw and felt things…”
