Overnight, Saturday 19th June. It's not the Solstice but it's as near as makes no difference, apart, of course, from something like 30,000 people crowding round Stonehenge.
Castle Cary to Pewsey via Glastonbury and Stonehenge.
I've just booked tickets from Paddington to Castle Cary for £10.50, Pewsey to Southend Vic, £8.50. For some reason, the really cheap through tickets I bought last year aren't available on the way out.
I'm booked on the 13.30 from Paddington which requires a change at Bath, and the 10.06 from Pewsey which goes straight back to Paddington.
The plan will be to eat curry in Glastonbury, climb the tor, watch the sun set, cycle to Stonehenge, carefully avoiding being knocked off by a badger, watch the sun rise, cross the Lark Hill Artillery Range, eat breakfast on the north side of Salisbury Plain (bring your own and something to cook it with) and then pootle back to Pewsey in time for the 10.06.
