We have Croquet sessions four times a week. There are competitions and more serious croquet available to those that want it. We mostly play Golf Croquet, and also a local variation called The Gaddesden Game.
The best day to join in is Sunday when there are people around from 10 in the morning through to 4 in the afternoon. Tea, coffee and other supplies are available in the clubhouse but if you are thinking of staying all day, it's worth bringing a packed lunch.
