Lambafellsgjá is a dramatic and accessible fissure located on the Reykjanes Peninsula, close to the distinctive mountain Keilir. The fissure is part of an active fracture system and offers a rare opportunity to observe the geological processes that have shaped the peninsula over thousands of years.

A short walk leads from Eldborg to Lambafell, where a well-defined path guides visitors all the way to the lower end of the fissure. Lambafellsgjá is deep, narrow, and steep in places, yet generally easy to traverse, making it a popular destination for hikers seeking a safe and immersive experience of Icelandic fissures.

Walking through the fissure is a unique experience, with towering rock walls rising on either side and creating a striking natural corridor. The walls clearly display signs of volcanic activity and crustal movement, revealing layers of lava and fractures formed during past eruptive periods on the Reykjanes Peninsula.

The surrounding area is rich in natural attractions that can easily be explored in the same trip. Nearby highlights include the geothermal area of Seltún, the colorful hot springs of Sogin, and the serene Grænavatn. Also close by is Kleifarvatn, one of the largest lakes on the Reykjanes Peninsula.

The region also holds cultural and historical interest. Close to the fissure stands Krýsuvík Church, a reminder of former settlement in the area, while other nearby sites such as Skátalaug and lava caves like Eldsmiðjan offer further insight into the natural and human history of Reykjanes.

Lambafellsgjá is therefore an ideal destination for visitors wishing to experience Iceland’s raw geological power within easy reach of the capital area. The combination of fissures, volcanic mountains, geothermal activity, and lava fields makes the area one of the most diverse outdoor destinations on the Reykjanes Peninsula.
