In Summer, the courtyard at Somerset House is all about splashing in fountains (kids, mostly, but sometimes adults will have a go as well). In Winter, it becomes one of the most popular spots to go ice skating. This year, the ice rink is open from Nov. 14 through Jan. 13, 2019, and it's £11 (or about $14) a pop. Hot chocolate and pretty Instagrams are required.
