St Mary's Pool - Isles of Scilly

Anchoring - FREE

St Mary's Pool sits just outside St.Marys main harbour which us heavily trafficked with a mix of private and commercial pleasure vessels, a large ferry, and fisherman.

For this reason the harbour master will maintain an open space near the entrance of the harbour where many boats can end up dropping their anchor in as the anchorage gets very busy.

It's a sandy bed with some seaweed dotted around but the hold has good when we stayed there for a few days.

We left Cadoha several times for extended periods as we ventured off on walks around this stunning island, including stopping for lunch where we could look down on the anchorage from a great vantage point.
