I always get a thrill when visiting a new site. Obvioulsy this can range from relief from actually just finding the place, to the 'WOW' sites and on occasion the truly 'jaw dropping' sites. I also enjoy re-visiting sites but it is never quite the same as the first time you visit. Also, re-visiting sites at different times of the year / weather conditions can obvioulsy make a big difference. Avebury is my favourite area to visit - I try to make at least 2 or 3 trips per year and there are still many sites near Avebury I haven't seen yet. Just off the top of my head to name 3 'Jaw dropping' sites - Castlerigg Stone Circle, Avebury and Great Orme copper mine (the huge underground chamber).
