My husband and I are Americans, in our 60s, who like to do long distance walking, from b and b, to b and b. We would like to spend a few weeks in the Channel Islands next summer, and spend 5 or 6 days walking. Does anyone have any suggestions for which island would be the best to do this on? Good walking guidebooks? We are also interested in day walks for the rest of the time. We are not interested in paying a company to set this up for us; we can do this, once we decide where we are walking. Also, is it possible to avoid renting a car and just rely on buses and the occasional taxi?
