You're in a stunning part of the world Dave, possibly my favorite.
The little hamlet of Rosevine, the little road that leads down to Porthcurnick beach is beautiful. I've been fortunate to stay in St Mawes quite a few times, I always take the ferry over to Falmouth, just for the trip!
King Harry ferry is perfect, a must do little journey. You might as well visit Trelissick Garden while you're that close as well.
I want to be there.....!!😁
