Planning trip to London, UK -- paranormal sightseeing inquiry

[Wednesday]

I know this may be a longshot, but maybe there are people that can point me in an interesting direction. I've been a fan of Art Bell since I heard him for the first time syndicated to my local area back in the mid-90s and still have cassette tapes of recordings I made.

Next April I plan to be in the London, UK area and have searched this forum for anyone talking about visiting paranormal-type sights, but never found much. Are there any people living in or are from the UK area and have you visited any "energy" places? I know about Stonehenge and Avebury for pagan & energy locations. Does anyone know of lesser known places in the London area or accessible by train within an hour or so?

I'll be there likely around the time of the full moon on Apr 25, 2013 â€" 20:00 (GMT) and was planning on visiting Avebury that day and walking to Sillbury Hill on a path from Avebury.  Has anyone done this in recent times that could offer any advice? Would you recommend the one hour dowsing tour mentioned here: http://www.theaveburyexperience.co.uk/aveburytours.html? Or do you know of similar knowledgeable guides in that area?

I am also fascinated with the topic of ley lines. I plan to be in London for about a week, but I think some of the sites I visit will be on the ley lines crossing London and also have read about the ley lines at this site http://www.kch42.dial.pipex.com/keys_location.htm.

You can private message me if you don't want to post your favorite places on a public forum. Thanks in advance if you want to discuss.
