Hi Marcelo, Your two best bets for exploring the Cotswolds without an auto are probably Oxford or Moreton-in-Marsh. On the one hand, Oxford is a fine destination in, and of itself. The university's grounds are reason enough to visit. Then again, Moreton-in-Marsh is more centrally located in the Cotswold region. From Moreton-in-Marsh you can access countless walking trails which lead to more of the villages in the Cotswold area. Both Oxford and Moreton-in-Marsh are transportation hubs within the Cotswold. Both have several coach lines running through them, which connect to other towns in the area. From Oxford, you can board coaches which service Witney, Burford, Fulbrook, Milton-under-WychwoodNorthleachCheltenham, Charlbury and Chipping Norton. From Moreton-in-Marsh, coaches connect you to the villages of Cheltenham, Bourton-on-the-Water, Stow-on-the-Wold, Stratford-upon-Avon, Chipping Campden, Cirencester, as well as Northleach. Personally, I prefer Moreton-in-Marsh. I like it, as well as the other locations that are accessible by both rail and walking. While in Moreton-in-Marsh, stop in for a pint at the Black Bear Inn. Great pub, great people, great beer. What more could you ask for? Happy travels!
