Has anybody done a small group tour to see Stonehenge and Bath with International Friends? Or does anyone know a great small group tour company?
I don't know International Friends. London Walks is a good outfit that does day trips to Stonehenge and Bath (separate trips), as well as lots of walks in London, see http://www.walks.com/. I've done their local walks and they are excellent, I'd assume the same for the longer trips.
Evan Evan Tours is another option. I know people who have used this tour company and speak highly about it. I love London Walks as well.
