If we stayed in Salisbury would there be any buses to take us to Stonehenge for the autumn equinox early that morning?
I believe all the celestial events are a big deal at Stonehenge. I believe the guard said that they had 25,000+ for the last Spring equinox. There will probably be a bunch of tours and transport possibilities but it will also be crowded by people from... let's go with "all walks of life" on the day. If you really want to go I would plan to book something ahead of time since it'll probably be something of an event. Have fun,
