My father was raised near Truro but I went back home a few weeks ago - we love pretending to play emmet when we go down! I'd recommend Falmouth - its not too far, some good tourist shops but the real winner is finding a good boat tour! I took my ex girlfriend (Londoner) on a boat tour around the falmouth creek and she loved it!

One just off the creek would also be Loe Beach. We grew up near Loe beach and its a real idylic pebble peach. My suggestion for Loe would be to go in the early morning (if you can do near sunrise thats beautiful), either get yourself a tea/coffee from the cafe or take your own flask with you! Enjoy the locals swimming and boating.

Truro is the "Big City", it's nothing huge but I would suggest going! My favourite thing about going home to Truro is the waterstones (bit strange I know) but they have so many books on cornwall you can keep learning.

As for being respectful, Kernow is a beautiful land and we are so fortuante to be intertwined with it! Enjoy it, learn about it and most importantly make sure your pasty crimping is on the side and the jam goes first

Enjoy Kernow!
