A Tudor artillery fort above Tresco, now reduced to ruined walls, but reviewers visit as much for the walk and the views as the fort itself - a scramble up from Cromwell's Castle below, or a gentler approach from the Quay. There's no entry fee and nothing staffed; what you get is the setting.
Worth the trip
The views across the Isles of Scilly from the top - reviewers rate them above the ruin itself.
Before you go
The direct route up from Cromwell's Castle is a scramble rather than a walk - if that's not for you, go via Back Lane from the Quay instead for a gentler climb.
The available reviews for King Charles's Castle are consistently positive, with visitors praising the walk up and the fantastic views across the surrounding islands and sea. No entry fee and dog-friendly access are noted as bonuses, and reviewers report no real downsides to the visit.
