A short walk around Wells, including around the Bishop's Palace (the free access bit - but if you have a Gardeners World 2 for 1 Card bring it along for access to the Palace/Gardens after the walk) and finishing at the Cathedral. The weekly market will also be on, and the walk should finish in time to visit it. All hard surfaces, so suitable for all.
Most walkers will meet at Bristol Bus Station, Bay 18, at 0925 for 0937 376 bus. Note that the weekly market is on, the bus may well be busy. We will get out by the market at 1050 approx. rather than at the bus station in Wells. End: approx. 1230. There are hourly buses back to Bristol (1247 being the first after the walk finishes). Walk is about 2 miles but of course we will have many stops en route
