If you climb Glastonbury Tor early enough in the day, you'll avoid the majority of tourists that inevitably end up swarming around at the top later on. The climb itself is fairly steep, and takes about 15 minutes if you are reasonably fit. There is a path which helps with the ascent but there are steps as well, making it a bit tricky for wheelchairs and pushchairs. We ended carrying our 3-year old, who got tired about half-way up. You never can tell what the English weather will do, but we were lucky enough to get a fine day, with brilliant views of the town and surrounding countryside. There is not a huge amount of room at the top, so it’s not such a great spot for a picnic. But you can sit down and have a morning snack. If its windy you can sit right at the base of St Michael's Tower for shelter. At the bottom of the tor is much more room for picnicking. We got the little shuttle bus from the town centre, as parking at the site itself is limited.
