1/2 term activities

[crescent]

Hi - I'm looking for 1/2 term activities for my 9 and 11 year old - it's a bit tricky for secondary school age I am finding. Lots of the stuff we used to do is 5-11, but quite 'young' for him now. We've cycled at the velodrome, played tennis - anything else? Any tips gratefully received!

sports clubs at Holiday Drop Off is great. Dulwich Hamlets also do one I think.
