The "Hafnarholmi" in Borgarfjordur eystri is an area highly suitable for birdwatching. On the premises there is a staircase leading up to a platform where one can get closer to puffins and the birds of the sea than ever imaginable. The puffins arrive in April and disappear overnight around August 15th. Underway to Hafnarholminn one enjoys good close-ups of vivid birdlife and the artic tern nests along the shore and on banks of the river. The harbor proudly raises the blue flag indicating that the inhabitans are respectful and attentive towards their surroundings.
