'I like climbing trees here, it’s a challenge.' - Jordon, aged 8

There are thousands of trees that are ideal for climbing at medieval Hatfeld Forest, as well as for hiding behind and building dens against. Just look out for the really old ones as at the grand old age of 1,200 they don’t like being trampled on too much – so it’s best to stick to the younger ones.
Hundreds of bugs, birds and bats live in the forest – can you spot their homes and tick off 'discover wild animal clues' from the 50 things challenge.
