Tour Description

Our volcanic adventure begins when we collect you from Reykjavik in our SUV. The tour always takes place in small groups (a maximum of 6), ensuring that you can maximize the knowledge of our expert guide, who will be with you from start to finish. Then, almost instantly, we will find ourselves in a spectacular moss-carpeted lava field, replete with smooth petrified Pahoehoe lava, which creates a stark contrast with the foreboding and craggy AA lava rock formations. In times gone by locals described this volcanic landscape as the ‘badlands’, because it was impossible for both people and livestock to traverse them. Whereas today, they are a truly memorable sightseeing opportunity, offering visitors the chance to explore an otherworldly landscape that perfectly encapsulates the land of fire and ice. Our friendly guide will tell you everything that you need to know about it and take you to a few photogenic places located off the beaten track, which are ideal for selfies.

Lake Kleifarvatn in Reykjanes Iceland

Lake Kleifarvatn or the Black Lake

Mid Atlantic Ridge & Lake Kleifarvatn

From there we will proceed into the heart of the iconic Mid Atlantic Ridge, which bisects the continental plates of Eurasia and North America. There we will find the spectacular Kleifarvatn Lake that is also known as the Black Lake. It is the deepest in all of Iceland and is actually a massive volcanic crater that was hewn into the landscape millions of years ago. It stretches down to a depth of 97 meters in places, which has fed many local legends about the lake. Foremost of these are the tales of a colossal monster that resides in the blue depths of the lake, which is the size of a whale, but shaped like a worm: Iceland's version of the Loch Ness Monster. The lake is also totally unique because it has no natural water sources flowing into it, instead, it is only topped up by rainfall and geothermal activity.

Kleifarvatn Lake has become a very popular spot for brave divers and snorkellers, seeking to explore the incredible geothermal springs that are found in many parts of the lake. Our friendly guide will tell you all about the incredible mythology that surrounds the lake and maybe, if we are really lucky, we will catch a fleeting glimpse of the legendary creature.

Seltun Krysuvik hot spring area Reykjanes Iceland

Seltún Hot Spring area and mudpots - here you can stand on a steaming volcano!

Krýsuvík / Seltún Hot Springs & Mudpots

Our next stop will be one of Iceland's most iconic geothermal sites: the multi-colored, seething mud pots of Krysuvik, where clouds of steam rise up off the fumaroles. This is your chance to walk safely on a boardwalk above the volcano's magma chamber - basically, standing on a steaming volcano!

We will pick our way through this majestic volcanic landscape, pausing on a boardwalk above the impressive magma chamber, to observe the groundwater being turned to steam just 4 kilometers below. This combined with the stunning blood red color of the hills that surround it makes for an alluring sight that everyone is bound to appreciate. It is also one of the best places in Iceland to gain an insight into just how vicious and powerful nature can be, making it a magical experience that will remain with you for the rest of your life.

Leidarendi Lava Cave

Our final stop will be Leidarendi, an incredible lava tube cave that was created by the fiery anger of the Leitahraun eruption, which occurred to the east of the Blafjoll Mountains around 5200 years ago. Lava tube caves are a totally unique natural phenomenon, which is created when streams of boiling magma are suddenly cooled, creating stunning rock formations that are dyed various different colors. Upon arrival, your friendly guide will give you a quick safety briefing and tell you everything that you need to know about them before we head into the cave, which is equipped with a walking platform and lights ensuring that it can be accessed by everyone.

Once in the cave, the underworld will great you with rainbow-colored rocks that have been dyed magenta, ruby, amber, and turquoise. Then as we push deeper, we will find incredible rock formations, replete with stalagmites and lava straws dangling from the ceiling. This unmissable opportunity to see the inner-workings of a volcanic eruption should not be missed and is the perfect way to conclude our tour.

We will stop for a cup of traditional Icelandic hot chocolate at the conclusion of this exhilarating underground adventure before we head back to Reykjavik.
