The number and variety of birds that arrive here on migration in Spring and Autumn can be spectacular, and North Ronaldsay is well-known as one of the best birdwatching sites in the country. The observatory also provides a variety of comfortable accommodation, including guest house, hostel and camping area, and a shop with groceries and other goods for visitors to the island.

There is a cafe at the Observatory, open between 12pm and 2pm, and evening meals can also be arranged.
