Iceland Volcanic Landscapes Adventure Lava Tunnels and Craters

We'll start the day with a swift and easy pick up from selected locations throughout the capital city Reykjavík

Raufarhólshellir, one of Iceland’s longest lava tubes (1,360 m), offers an easy walk through striking volcanic formations and vividly colored mineral walls. Expert guides lead you safely through the cave, sharing its history and highlights on this approximately 1-hour tour. Afterward, you’ll be dropped back in Reykjavík for free time before pickup for the second part of the tour.

Your first stop of part two is Kleifarvatn, the largest lake on the Reykjanes Peninsula, about 30 minutes from Reykjavík. One of Iceland’s deepest lakes (97 m), it has no rivers feeding it and is sustained entirely by groundwater filtering through porous lava rock. Surrounded by colorful hills and dramatic lava formations, the lake is also home to local legends of a mysterious worm-like creature—stories your guide will share as you take in the scenery.

Next, explore the Seltún geothermal area in Krýsuvík, famous for its Mars-like landscape of steaming hot springs and vividly colored hills. Mineral deposits paint the terrain in reds, yellows, and greys, while the scent of sulfur signals intense geothermal activity. Wooden walkways lead past bubbling mud pools, hissing steam vents, and active fumaroles.

After a short drive, visit Grænavatn—“the Green Lake”—a volcanic crater lake famed for its vivid green color caused by high sulfur content. This peaceful spot is ideal for photography and a striking example of Iceland’s unique geology.

Visit Nátthagi near Fagradalsfjall, the site of Iceland’s 2021 volcanic eruption—the longest of the 21st century after 6,000 years of dormancy. Explore vast lava fields shaped by solidified flows, with a short hike to the Nátthagi viewpoint for a closer look at the frozen lava river.
Note: The hike to the lava field about 20 minutes one way over uneven, rugged terrain.

Arrive in Grindavík, a town shaped by recent volcanic activity. Once evacuated due to eruptions, it has now reopened, though many houses remain abandoned and roads show earthquake damage. Explore this unusual, quiet town and witness the raw power of Icelandic nature up close. We’ll stop at a local restaurant for 15 to 20 minutes to grab refreshments.

Drive through the Sundhnúkagígar lava field near Grindavík, formed by Iceland’s recent eruptions, with steam still rising from the fresh volcanic terrain. After exploring, return to Reykjavík through scenic countryside, arriving in the early evening with time to relax or enjoy the city.

After the tour you'll be dropped off at your original pick up location
