Come play on the sound sculptures, see the llama, explore the aquarium and museum. Bring food or purchase food from the Farmers' Market. Bring kids if you have any - this is a child friendly event. There is lots to do inside and a coffee shop/cafe if the weather turns ugly.
How to get there: the museum is a 10 minute walk up the hill from Forest Hill station , trains from London Bridge or the overground West Croydon or Crystal Palace Line.
Meet by the sound sculptures near the bandstand - to find it just enter the museum drive and keep straight on up the hill. The sound sculptures are just to the left before you get to the Farmers' Market.
