England: Stonehenge
A must visit for tourists is Stonehenge! I went with a student tour group, and had audioguides to use. But audioguides are free to download on a smartphone.
Back from the stones to the visitor center is a nice mile or so of a walk filled with rando cows chilling and graves of old old stonehenge time people. The walk was also really flat 360 degrees, and in nice weather, a totally worth walk, although there is a shuttle available between the stones and the visitor center.
At the visitor center, I saw that they sold rock cakes, which is mentioned in Hagrid’s hut a lot, so to figure out what they are, i bought one. its just a fat crunchie cookie.
