Fascinating place with the ability for you to climb to the very top gun platform on the roof via a very tight stare. Having ability to do this affords a real sense of what it was like to have been stationed there.

A walk around Tresco always needs a visit to Cromwells Castle, there are great views up New Grimsby Sound and across to Bryher. Look for the old graffiti within the building.

Nice view. Good hiking to the castle as well. Dog friendly.

A castle that looks like a castle should do! This is the sort of castle I imagine whenever I hear stories of dragons, knights and princesses. Perched on a rocky outcrop overlooking beautiful Caribbean-esque sea, this is a great castle which is remarkably intact. Fascinating history and a photographer's dream.

One of the best things to visit on Tresco along with King Charles Castle a little further up the hill. You will need to walk along a narrow coast path which takes about 30 minutes from the harbour. There is no entry fee and the structure is well maintained with some narrow steep steps. Climb to the top for some great island views.
