Tintagel and Boscastle can be challenging places to get to if you don't have a car. Looe is on an offshoot of the railway line and they seemed to have plenty of live music going on in the pubs when I was there last year. I grew up in Cornwall. I can say that the geographical distances are not great, but Mr.Red is quite right when he says that they can be deceptive. The rural way of life is not always geared up to providing transport for night revellers. It's a good idea to stay somewhere near the venue if you are planning a night out and do not have a car. Plenty of good beer of course. Have fun and tell us about it.
