Questions that ask for locations dont go down well on here mate, i reccommend you search the site and google maps to find places to explore, use the searchbox and enter locations close to you to find something local. Also, if you have questions related to exploring its best to put them in the beginners section of the forum, this ill probably get deleted. Good luck exploring nonetheless
Yup, not much in Dorset to be honest and no asylums, there are some good sites around but you have to be quick before the PIR's and metal boarding goes up these days!
