My husband and I will be in Bath for 4 days in October. We would like to spend 2-3 days in the Cotswolds, but we've read (in posts that are 5 years old) that it is difficult to visit using public transportation. We are in our 70s and in good health for our age. We did book two tours with MadMax (Stonehenge and Cotswolds) so at least we'll see a little of the Cotswolds, but we would love to be able to take some walks. We would appreciate any advice.
