The annual festival helps build and repair the Grade-A listed dyke which encircles the island and protects the unique flock of seaweed-eating sheep.

Volunteers from all over the world are welcomed to North Ronaldsay for the two weeks of the festival (usually during July and August) and take part in a dyke-building programme in the mornings and afternoons, rewarded by evening events, island hospitality, and the opportunity to learn new skills and strike up new friendships. The cultural program varies each year but often includes knitting & felting workshops, open music sessions, dances and tours of the local lighthouse.

It's a great opportunity to help out a remote island community while also experiencing the island’s unique culture and heritage.
