Enjoy a quieter moment colouring. Can we colour in the entire shadow of a tree by the end of the day? Family craft corner Get ready for the party of the year by make your very own birthday hat. Hedgehog highway sign making One of the best ways to encourage hedgehogs to visit a new area is to cut holes in fences. We have our own series of fence holes between the Nature Trail and the Gardens, but no sightings of any spiky friends yet. Help us encourage them to pop in by making tiny signs for our Hedgehog highway. Games Smallympics One trolley, two umpires and classic eccentric games for all.
