I will have a group of between 20-25 college students in London from mid may to mid june. As a possible outing I was contemplating the Cotswolds. any suggestions as to the best towns to visit trails to follow etc... have been to UK a few times but only to London, Canterbury and Brighton. Thanks for any suggestions.
Rick talked about visiting the Cotswolds in his Facebook blog yesterday.
Broadway is quite nice (http://www.broadway-cotswolds.co.uk/), but a little hard to get to without your own transportation. Moreton-in-Marsh is another place to consider.
This site seems to have a selection of walks in the Oxfordshire Cotswolds: http://www.oxfordshirecotswolds.org/site/activities/walking/downloadable-walks
If you don't have a car there is train service from London to Moreton-in-Marsh and then bus service to several villages from there. My advice is do a little research on each of the villages you can reach from Moreton-in-Marsh and then decide based on what you like and want to do.
