I will be visiting England Solstice week by rental car. Would love to see the following, The stone circle at Avebury, Glastonbury Abbey and the Tor. The hill figures of The Long Man. Cerne Abbas. The White Horse. It will be my first trip to the U.K. and I will be travelling alone without reservations. I also would like to be at a (special place for the sunrise on the 21st. Are most of these sites relatively close? and is there anyone with some sage advice for this naive American who is looking forward to seeing his ancestral home? I would appreciate any advice.
