Best waiting till later in the day for visiting the better known places, the tourists get scared when the daylight dissapears, theres rumour thats when all the witches come out!!..hehehe...visit 'Boscawen-un' on the full moon and youll soon realise the rumour is actually a fact!, hehe!.I find after 7pm ish best if you want to be on your own, late i know but worth it!, it helps too if you visit these places when the tide is on the 'push'(coming in)..find a 'fogou'(halligye fogou is a good example) if you can, Boliegh is the best but you have to ask Jo at the CAER prior to visiting...sit inside one and that alone will make the journey to Cornwall worthwhile!.
