Reykjanes: Home to 55 Geological Sites

Centuries of Volcanic Activity

Reykjanes can truly be described as the youngest part of Iceland due to the frequent volcanic eruptions in the Sundhnúkur crater row in recent years. Volcanic activity over centuries—and especially in recent years—has shaped the Reykjanes landscape, which is covered in lava fields as far as the eye can see. Because of its lunar-like appearance, astronauts preparing for missions to the Moon trained here in the 20th century.

When exploring the peninsula, the first stop should be Kleifarvatn, the largest lake in Reykjanes. Situated between steep slopes, nearly 100 metres deep, it is a popular destination—particularly for those who wish to dive into its depths and experience the geothermal activity on the lakebed. Nearby is Krýsuvík, a geothermal area filled with bubbling mud pools, hot springs, steam vents, and a strong sulphur scent. The area is well equipped for visitors, with marked paths that protect them from the boiling ground beneath.

Blue Lagoon and Grindavík

This is only the beginning of a journey around Reykjanes. The Blue Lagoon is an essential stop. Its blend of silica, algae, and geothermal seawater creates a primal yet refined bathing experience. Due to its popularity, advance booking is strongly recommended. The Blue Lagoon also offers accommodation at Silica Hotel and the more exclusive Retreat Hotel, which features a private lagoon reserved for hotel guests.

A short drive from the Blue Lagoon lies Grindavík, a town that was evacuated in 2023 due to intense seismic activity and volcanic eruptions. The town still bears the marks of these events, but its residents are determined to rebuild, with people beginning to return to their homes in late 2024.

Just ten minutes from Grindavík is Brimketill, a natural rock pool carved into the cliffs by the sea. It is strikingly beautiful yet especially dramatic when waves crash into it. This natural wonder is best viewed from the designated viewpoint above, as the forces of nature here are unpredictable and there are no safety barriers in the area.

The Bridge Between Continents

Eight kilometres away is Gunnuhver, a powerful mud pool that can be viewed from two platforms offering a close encounter with nature’s raw energy. Visitors can hear the roaring of the earth and feel the steam rising from the ground. The surrounding high-temperature geothermal area feels otherworldly and is a truly unique sight.

Further inland on the Reykjanes Peninsula stands the Bridge Between Continents. Built where the North American and Eurasian tectonic plates meet, the bridge symbolizes the connection between two continents. Standing at its centre places you directly on the Mid-Atlantic Ridge—and simultaneously between North America and Europe. Nowhere else in the world is the ridge visible above sea level in this way.
