You can park all day foc, even if not visiting the museum. Doubtful anyone would do this as there's not much else you can do when parked up here. The Museum is excellent but they stricktly enforce no parking after 6pm
East of York, famous from the Battle in 1066 (the other one which Harold won). Nice CP with toilets opposite. Not suitable for onite but park all day foc and walk along the river and visit the old town.
