We love Cornwall. If you like gardens then Trebah which are privately owned are lovely. A nice restaurant at the top serving homemade food and you wander down a hillside, through the gardens to a beach at the bottom - take a towel to sit on as stoney and enjoy the view and an ice-cream before the hike back up. Well worth it, a little piece of heaven. Padstow nice but very busy. My husband, who dosn't do queues', did so for an hour for Rick Steins fish and chips and said they were worth it!
Hope you enjoy whatever you do. We're down early Aug and looking forward to it.
