Reykjanes is a peninsula in Southwest Iceland, characterised by immense lava fields, volcanoes and strong geothermal activity.
Volcanic & Geothermal Activity
The peninsula runs along the Mid-Atlantic Ridge where the Eurasian and the North American tectonic plates are drifting apart. Because of this geological setting, the whole peninsula is extremely volcanically active, covered with lava fields and volcanoes and small earthquakes are very common there.
During the middle ages, many eruptions occurred in Reykjanes, but no eruptions have been recorded there for the last 500 years.
The main geothermal areas of Reykjanes are Gunnuhver, Krýsuvik and Svartsengi. Various mud pools and fumaroles can be seen at Gunnuhver while Krýsuvik is characterised by hot springs and mud pots that bestow multicoloured hues upon the soil. The green crater lake Grænavatn is also an impressive sight.
Svartsengi is home to a geothermal power station that produces 76.5 MW of electricity from the 475 litres of 90° C warm water that gush from the earth per second. The mineral-rich surplus water fills up the Blue Lagoon spa.
Nature & Wildlife
Reykjanes' cliffs are teeming with birdlife. Its best-known bird colony resides in Krýsuvikurbjarg which is the nesting place of approximately 80 thousand seabirds. North of Krýsuvíkurbjarg is Kleifarvatn, the largest lake on the peninsula and one of the deepest in Iceland.
Reykjanes is hammered by some of the most breathtaking breaker waves in the world. A short drive from Krýsuvík is Selvogur where one is able to witness some of the country's greatest waves. On Reykjanestá, the southwest tip of the peninsula, the waves are known to reach heights of 20-30 meters.
The peninsula's north side is dotted with fishing villages and towns, most notably Keflavík, Sandgerði, Garður and Vogar. Grindavík town is located on the south shore of the peninsula.
Near Keflavík is the Miðnesheiði heath, where the international airport, Leifsstöð (also known as Keflavíkurflugvöllur or ‘Keflavík Airport’) is located.
The World-Famous Spa
On the southern tip of the peninsula is the Blue Lagoon geothermal spa, an ideal place for relaxing and bathing.
Leidarendi is a lava tube located in the Tvibollahraun lava field, close to the Blue Mountains in Southwest Iceland, about a 25 minutes drive from Reykjavik.
Go here to find the Leiðarendi cave tour.
Leidarendi is notable for its incredibly diverse and colourful scenery, and is considered a prime example of an Icelandic lava tube.
A distinctive feature of Leidarendi is various lava flakes that have fallen from its walls and roof, due to frost and erosion. These flakes indicate the many different lava streams that have flowed there subsequently throughout the ages. In the cave you will further see cave walls polished by lava streams along with stalagmites, stalactites and other fascinating formations. In winter you are likely to see glistening natural ice sculptures in the cave, adding further beauty to the already otherworldly scene.
As the cave is sensitive ask you to show uttermost care, so you and others may continue to enjoy the marvelous sights of Leidarendi and learn firsthand about Iceland's geological history, to which the cave bears proud witness.
The Blue Mountains are a beautiful mountain range of the tuff type, located around 20 km from Reykjavik, by the lava plateau of Hellisheidi. The mountains are the most popular skiing venue for the people of Reykjavik and its surroundings.
The mountains offer excellent slopes for downhill skiing, cross-country skiing and snowboards. The area is strong with volcanic activity, with frequent earthquakes and the lava that became Kristnitokuhraun lava field flowed from there in the year 1000. Kristnitokuhraun is located at the outskirts of the Blue Mountains. Also in the area is the fascinating underworld of the lava tube Leidarendi.

What to bring:
Rut gave us a great lava tube tour. It was just us unto a couple of other groups showed up near the end. Definitely worth the trip, and worth the cost. I know this may sound strange, but I found the sheep remains near the end of the tube as fascinating as the rest of the tour, LOL! I want to go back and do the tour with the elevator that descends into the volcano cauldron.
The tour was wonderful! We went early in the morning so the group was small and it wasn't crowded in the caves at all. I think we were the only ones in there and saw another group coming just as we were leaving. Our tour guide was very knowledgeable and helpful along the way. She definitely made the experience even better! The caves themselves were amazing and there was a bit of crawling but not bad at all. I would recommend booking a tour though this company for sure.
Had so much fun on this tour, with a small group this tour became very interesting and personal and we got to know the other people on the tour. The lava formations are interesting and the cave keeps surprising you, be prepare to crawl a bit! Loved the surroundings as well, beautiful lava landscapes. The guide was very friendly and enthusiastic.
Take this tour if you are in Iceland. We had a great time with a small group of only 6 people. The guide was very friendly and informative and we were the first group to arrive in the morning so we had the cave for ourselves and got to experience the darkness!
This tour just wasn't active but very interesting as well! I'd definitely recommend. Great value for money.
I loved the tour! The experience felt really local. Beautiful area. It was really not one of those touristy caves. The guide was great and answered all of our questions! Highly recommended.
