Extreme Iceland offers tours to the three caves and the geothermal areas every season of the year.

Description du circuit

The roadway to the south shows how great volumes of lava thrust themselves into the surging sea in the inlet of Herdisarvik. We’re able to see where it tumbled off 10.000 year old cliffs into the fizzing ocean. Great amounts of lava also streamed down two gorges known as Mosaskard and Natthagaskard. Uphill from here are 3 very interesting lava tube caves.

The colour of this rock is reminiscent of it's former temperature

We start the tour in Reykjavik and from there we drive to Kleifarvatn lake and from there to view the hot cauldrons by Seltun. From there we head to Austurengi geothermal area and watch the magnificent thermal springs  which are among the largest thermal springs in Iceland, if not in the whole world. When in Herdisarvik in the southern part of the Reykjanes peninsula, we’ll take a stroll down to the rugged coastline to watch the surf break against the black rocks on the beach. These waves are generated in the far reaches of the South Atlantic Ocean, for the fact is that the next land due south is Antarctica.

Natthagi cave is full of rocks

After having inhaled and filled our lungs with the fresh Atlantic breeze, we head up the mountain through the lava in Natthagaskard gorge. As we get higher up, the scenery gets more beautiful and more terrific with each step. At the edge of the gorge there are 3 lava tubes that we are going to explore. Each lava tube has its own characteristics. Hallur is the first lava tube and it’s around 200 meters long. Hallur’s main characteristic is that it leans downwards due to the fact it was the passage for the lava flow down the mountainside.

Geologists love to see this kind of a structure

"Annar í Adventu" is another lava tube, 200 metres west of Hallur, and its length is around 220 metres. It has two openings. The southern entrance opens up on the sheer mountain face and from there the scenery towards the sea is amazing, this happens to be an uncommon sight from Icelandic lava tubes. Natthagi is the largest of those three caves, 400 metres long. Natthagi has 3 entrances or openings and they’re all skylights. Natthagi boasts of many beautiful lava formations and is among the more interesting lava tubes found in Iceland.

Wierd and wonderful sights await

After the cave tour, you are able to travel back the same way to Reykjavik or to take an alternative route to the Blue Lagoon to recharge yourself once again. Another possibility is to take the road to the villages of Þorlakshofn, Stokkseyri and Eyrarbakki where you would find a number of good restaurants that are pleased to welcome hungry and weary travelers.
