The North Ronaldsay Bird Observatory is situated at the south west corner of the island with outstanding views and an adjacent shell sand beach. Seals and the unique seaweed-eating sheep are abundant along the coast which skirts the 34 acres of croft managed by the observatory. The observatory sees spectacular bird migration through the island in Spring and Autumn. It offers a special attraction for those interested in wildlife, but welcomes all visitors. The Observatory Hostel consists of three dormitories and a self-catering kitchen in a converted barn and byre of the croft. The Byre sleeps four in two bunks and has en-suite washing, shower and toilet facilities. It is particularly suitable for family use. The Barn also sleeps four and shares facilities with the Bøl which has a single bunk sleeping two. Adjacent is the Observatory Guest House (3 star) which has a lounge bar and meals which are available to hostellers.
