Main image

St Agnes is a small inhabited island in the Isles of Scilly, off the southwest coast of England, and is part of the archipelago administered from St Mary’s. It is known for its compact settlement, beaches and surrounding coastal habitat.

The island is popular for coastal walks, birdwatching and quiet beaches; the shoreline and nearby islets are important for nesting seabirds and coastal plant communities. A sandbar links St Agnes to the adjacent island of Gugh at low tide, allowing an exposed crossing between the two.

Historically the island has had small-scale habitation and has been managed in part by conservation organisations; contemporary activity is largely seasonal tourism and local services. Facilities on St Agnes are limited compared with larger Scillonian islands, and visitors usually travel from St Mary’s by passenger boat.

St Agnes lies at the southern end of the inhabited islands of the Scilly group, a short boat trip southwest from St Mary’s and roughly 45 kilometers off the Cornish coast of southwest England.

  • Tidal connection: A low-tide sandbar links St Agnes to the adjacent island of Gugh, allowing pedestrian crossing at particular tidal states.

What to See #

  • Gugh tombolo: Gugh is a small neighbouring island joined to St Agnes at low tide by a sandbar, providing a short walk between the two islands when exposed.
