I took an excellent all day tour to Stonehenge and Bath with DayToursLondon.com. The meet up time was at 7:45 at the Gloucester Road underground stop so I had to get up at about 6:30.
I got there in plenty of time and had a coffee at Starbucks. The group on the was about 30 people and the guide was very informative and entertaining. He really liked to talk.
Stonehenge is an ancient burial site, a solar calendar, and based on it's size, an important ceremonial complex. It was built in prehistoric times about 5000 years ago and predates the Great Pyramids of Giza in Egypt. The big mystery of the site is how the ancient builders got the massive stones to the site, some from over a hundred miles away.
I endured the relentless icey wind and walked around the rocks a few times and soaked up the history of the place. Tourists are not permitted to walk among the rocks only on a path around them.
The old city of Bath is very quaint and attractive. It is a small city that is approaching a population of 90000 with many amenities of a larger city. There are ample bars, restaurants, museums, and other attractions catering to the large number of tourists that arrive there. The rolling hills surrounding Bath are full of scenic hiking paths which afford spectacular views of the city and countryside.
