Get your self a National Trust card if you don't already have one. Most of the coastline is owned by them so you will save on parking charges. As for your visit. Start with checking out the beaches, wet suits and surf or body boards to hand. Some have lifeguards, so pay attention to their flags. Visit St Michaels mount, Lands End and Lizard point, Minack theatre for some culture and Tate Modern, Pendennis and St Mawes castle, get a river boat trip from Falmouth up the River Fal to Truro or stop at the Hideaway pub on the way for lunch.. Don't forget it will be the Helston Flora Day on Wednesday, that's an excellent day out, don't forget your camera. The Eden project is brilliant, expecially their restaurant, wear comfy shoes, Penjerrick gardens is known for its Rhodendrons. Lost garden of Heligan and Charlestown port would make a good day out in the St Austell area. That's just for starters, hope you enjoy yourself.
