I quite like the Camel Trail. You're going to be riding along the end of the route of the rather grandly named Atlantic Coast Express that used to leave London Waterloo and finish in Padstow. On the section from Padstow to Wadebridge the scenery is open views across the Camel, and one rides over the girder truss bridge at Little Petherick creek. After Wadebridge, toward Bodmin you'll become cloistered in greenery, riding alongside a stream for part of the way. Being an old rail track it is of course quite level, so nice and easy to ride, good for families. Enjoy your time down there, the pasties, and the Sharp's Doom Bar ale!
