My friend works for a play scheme run by the zoo that are doing forest school for 8-12 yr olds at half term. Due to some sort of admin cock up, it hasn't been marketted, and they haven't got past the critical mass they need for it to run, which means that kids that are already registered on it will be disappointed.
If you like the sound of a halfterm spent playing in the woods, building dens and learning fire craft and survival skills, it looks brilliant. Sadly my kids are too young.
You can find out more here. It needs to be booked by end of Tuesday for them to carry on with it so get cracking!
(I feel I ought to add that I have no involvement with this, I don't work for them, they haven't asked me to do this. But it looks great and it would be such a shame if it had to be cancelled.)
