hello, welcome, i live in the vicinity!
Totnes--nice little shops, steep hill, hippies, China Blue(near train station) for great wet weather paint your own stuff, and good food.
Dartmouth,also quite good shops, tho the poor place had a fire a few weeks ago which destroyed some of the historical bits. The Sloping Deck restaurant is a must for a pasty, cream tea or huge slice of homemade cake. It's over the Butterwalk, and it is a sloping restaurant as it's so old lol!!!
You will be nearest to Blackpool sands, slapton sands, being in Ditsum ( how the locals pronounce it!!)
If you have a car check out Woodlands, which is a beautiful and brilliant play place, just outside Dartmouth. Kingsbridge is nice, and places that I love are Bantham beach, Hope cove, --totally oldy worldy tiny fishing vilage.
i am sure the sun will shine, it's been fab until today, but tis blowing over by 2morro!!
