So this may come across, to some of you, as a silly post and I may seem ill-informed. I have lived here about eight years now but I have no idea where are the best gatherings or places to visit in the UK hippy wise. I know quite a lot of places in the US because of my cousins going to as many of them as possible. I live in the south of England as well. I've heard of stuff going on up North but that's about it. I'll be going to Brighton Pride in August and I know of the Psychedelic Society but that's almost all I know about things to do. If anyone can recommend other things lemme know!
The Small World Festival in Kent happens in May and August, a small five day festie which is wind and solar powered: https://www.efestivals.co.uk/festivals/smallworldsummer/2017summer
If you are looking for the getting back to Nature based theology of Hippy-ism (as well as Party Beano) - have you considered the 'gatherings' witch Pagans and olde world practices can offer? As you are South England based, Avebury (around 21-23rd September) or Glastonbury (town, the (Chalice) Well and the Tor) are areas where one can embrace the ambience of culture, of the old gods and spiritual connection - It's another side of discovery to be experienced ...... methinks
