Since we last visited Stonehenge 20+ years ago, they have reconfigured the site so you park some distance away and either walk or take a shuttle bus up to the stone circles. The current set-up gives the tourists a bit more room to spread out and creates a bit more of a sense of grandeur — in the old days the carpark was right next to the site, and you felt like you were being shuffled past as quickly as possible. English Heritage have also done a good job on the new visitors centre, putting a lot of oomph into a few small exhibits and having first-rate volunteers delivering commentary.
After Stonehenge, we headed up the road to Avebury to wander around their much-larger stone circle, and capped off the day with an Easter trail through the gardens of Avebury Manor.
