The annual conker smasher is back for 2025, with Londoners of all ages gathering on Parliament Hill by the bandstand to try their luck in the very British battle. Arrive by 12.30pm for registration if you’re serious about competing: there are separate categories for under-eights, 8-12s, 13-17s, and adults. Conkers are provided and rules and adjudication provided by the Grand Conker Meiste (so you can stop all that vinegar-soaking for starters).
There'll also be live music in the bandstand, and hands on nature activities led by local conservation groups.
