I've always wanted to see the South Downs around Beachy Head, Cuckmere Haven, and Birling Gap... I was thinking of staying in Eastbourne and taking the bus/hiking. Is this doable? (My experience with buses in rural England and Wales last year was that service has really been cut back severely...)
I'm traveling to the UK for two conferences in October and wanted to make a short trip of it: a few days in London (one conference is there), a few days in Cardiff (second conference is here, with a day trip to Bath by train and possibly a few days in Tenby if I can swing it, work-wise), a few days in Eastbourne. If any other advice for that part of England and Wales (that's doable on trains and buses), please let me know!
