Raufarhólshellir Lava Tube Cave

Raufarhólshellir lava tube was formed nearly 5,200 years ago, during the Leitahraun Eruption. We will enter through narrow cave entrances and find they reveal extraordinary scenery of lava formations and colors. You will also see natural stalactites and many different rock formations making this a majestic and almost indescribable experience. The caves become wide and high in places with an even floor, however, the trip can also be rather difficult in places. We recommend you wear good walking shoes or hiking boots which are suitable for walking on uneven lava surfaces.

The Blue Lagoon Geothermal Spa

After the caving experience we drop you off at a switching point downtown Reykjavik. You will have some time to have lunch, before a separate transfer to the famous geothermal spa of the Blue Lagoon.

The warm waters are rich in minerals such as silica and sulfur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases. Indeed, the attached Blue Lagoon Clinic is an internationally recognized psoriasis treatment centre. The water temperature in the bathing and swimming area of the lagoon averages 37-39 °C.

The Blue Lagoon is fed by the water output from the nearby Svartsengi Geothermal Power Plant and is completely renewed every 2 days. The water in the lagoon is used for both recreational and medicinal bathing.
