Reykjavik: Lava Tunnel & Reykjanes Lava Fields Tour｜Iceland

Please kindly recheck the pickup details, meeting point, and session time stated on the voucher for your selected package.

Begin your adventure by exploring the Raufarhólshellir Lava Tunnel, one of Iceland’s longest lava tubes. Enter through a narrow opening and journey deeper into the cave, where naturally colored walls shimmer in red, violet, and turquoise from mineral deposits. Along the way, your guide will share the cave’s history, highlight its most impressive features, and ensure a safe, unforgettable adventure.

After the tour, return to Reykjavík for some free time before being picked up again for the second half of the tour. Head to Kleifarvatn, the largest lake on the Reykjanes Peninsula. Learn about the mythical worm-like monster said to live in the deep waters of Kleifarvatn as you enjoy the views of the vibrant hills and unique lava formations.

Next, visit the Seltún geothermal area in Krýsuvík, renowned for its Mars-like landscapes, full of hot springs and vibrantly colored hills that resemble the surface of another planet. Walk along the wooden paths, discovering multiple bubbling mud pools, steaming fumaroles, and hissing steam vents.

After a short drive, reach Grænavatn, which means “green lake.” This naturally formed pool is nestled in a volcanic crater and is known for the bright green color of its water. This serene oasis is a perfect spot for photography enthusiasts.

Next up is Nátthagi, the area near the Fagradalsfjall volcano, known as the site of the dramatic eruption in 2021. See a large lava field where solidified flows have created striking geological formations, including rounded lumps of black rock at the valley's edge, marking the point where the lava stopped. Take a short hike to the Nátthagi viewpoint to get a closer view of this frozen-in-time lava river.

As you reach Grindavík, be greeted by the eerie silence of a once-thriving town now deeply affected by volcanic activity. Since late 2023, many eruptions in the vicinity have led to road closures and evacuations of the residents, leaving the town empty and deserted. Recently, the town was reopened and declared completely safe for former residents to return and for visitors to explore. However, most of the houses are still abandoned, and the roads still show visible signs of damage from the seismic shifts. This unique opportunity allows you to observe the raw power of Icelandic nature firsthand.

Next, drive through the Sundhnúkagígar lava field, just outside of Grindavík. This land was shaped by some of Iceland’s most recent eruptions, which captured headlines worldwide. Witness the freshly created volcanic landscape with steam still rising from the ground.

After exploring this natural masterpiece, head back to Reykjavik, driving through the picturesque Icelandic countryside and sharing the highlights of an adventure-filled day.
