There's no shortage of trees in the forest. Some are very old and special, so please follow our tree climbing code, which you'll find in the Discovery Room.
Venture into the coppice and you'll find plenty of sticks for den building. There are lots of example dens so either improve an existing one or build your own.
Lay a trail with sticks and get a friend to follow it. Where will you take them?
With a huge grassy plain to choose your blade of grass from, you could make a grass trumpet and join nature's band!
Take off your shoes and feel the tickly grass, the bumpy roots or the squidgy mud.
Roll over a log and see if there are any bugs living underneath. Make sure you roll the log back to keep the bugs home intact.
Head over to the bird hide (by the side of the lake opposite the cafe) and see if you can spot some of our feathered residents.
Can you find your way around the forest - there are lots of green tracks and many look the same!
