The Ketildalir valleys are on the southern shore of the fjord Arnarfjordur. The best know of those valleys is probably Selardalur, a very popular destination because of the sculptures and buildings raised by the naivité artist Samuel Jonsson. Samuel is referred to as "the artist with the infantile heart". When he retired at the age of 72 in 1958, he pursued his dreams and became an artist. Mostly he created sculptures from concrete and carried the sand on his back from the shore to his farm Brautarholt. In his backyard, among other things, he has replicated the Lions Court in Alhambra. 

Selardalur also offers a wonderful panoramic view across Arnarfjordur, over to the 1000 metres high Kaldbakur Mountain, the highest mountain in the Westfjords.
