Why visit Kleifarvatn?
Kleifarvatn is the largest lake on the peninsula, set between the ridges of Sveifluháls and Vatnshlíð. Its broad surface gives the surrounding volcanic forms room to register: slopes, shorelines, and changing light.
The lake also belongs to the peninsula’s earthquake story, with its shape and water level connected to movement below ground. Look for the small details at the edge, then widen the view to the whole basin.
Perlan describes Kleifarvatn as a lake formed in a subglacial volcanic depression more than 10,000 years ago. Its water is fed by underground springs, so the dark basin can feel unusually self-contained as you look across it.
Walking and accessibility
Kleifarvatn is a natural lakeside destination with different viewpoints rather than one defined accessible visitor route. The official destination page does not specify wheelchair access or path gradients. Select a viewpoint that suits your needs and assess the ground before leaving the parking area; do not assume access to the shore.
