Hot Spring Snorkeling, Lava Caving & Aurora Basecamp

The ultimate Icelandic experience

Geothermal energy, lava caves and Northern Lights

The most adventurous day

There's no doubt that Iceland is probably the best place on Earth to see the forces of nature at work. This is true for the whole island and right here in the Capital area we are so lucky that we can witness nature's show just a short drive away from the city.

On this tour we take you to Kleifarvatn lake for a snorkeling tour, we explore a lava cave formed thousands of years ago and we top it all off with a visit to the one and only Aurora Basecamp Northern Lights Observatory.

Our Hot Spring Snorkeling Tour is an exclusive opportunity to swim in an active hot spring, among gas bubbles and sorrounded by fascinating, colorful motifs that the sulfur residues paint on the sandy bottom of the lake. You will be fascinated by the vast range of colors that go from white to yellow to orange and you will feel the most peculiar environment around you, which has often been described as swimming in a glass of champagne.

After the guided snorkeling tour, we will take you on a short drive to reach the Leidarenði lava tube. This cave system formed about 2000 years ago following very intense volcanic activity that interested the Reykjanes Peninsula. What we are left with is a 1000-meter long lava tunnel that showcases the most common features of Icelandic caves. We will gear up in helmets and headlamps and then start descending into the lava tunnel from the opening in the middle of a lava field. Once down in the tunnel, our lamps will shed light on a mesmerizing scenery made of bright colors ranging from yellow to red and even purple. For about one hour we will move along the tube and observe the beautiful rock formations, stalactites and stalagmites that populate the cave.
This tour is suitable for everyone, but please keep in mind that there are parts of the cave where the ceiling is very low or the floor is unstable and we will have to bend down, squat or even crawl through. We highly recommend you wear sturdy hiking shoes.

We will emerge after the caving tour to conclude our day with a visit to the unique Aurora Basecamp Northern Lights Observatory. These domes were built in 2019 to provide a unique Northern Light experience and you will visit the Dark Park, where you will find a lifelike simulation of the lights.
Additionally, the guides will give you tons of information and tips on how to hunt the lights and how to take pictures of them on your camera or phone.
