Local Grade: C. The crossing to Sully Island is across a stone causeway and care must be taken if the rock surface is wet from the outgoing tide. The crossing will only be made if the weather is deemed suitable. If any walkers decide not to cross to the Island for any reason, there is a cafe and pub on the mainland where they can await the return of those who have decided to make the crossing.
