We've come up with our top ten list of 50 Things to do before you're 11¾ at Hatfield Forest. Whatever the weather, there is always something to do. Pick up your free 50 Things scrapbook from the shop and get a sticker each time you complete an activity.
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 orchestra!
Hatfield Forest is the top place to look inside a tree. We even got a mention on Chris Evan's Radio 2 show. With so many hollow trees, take a look inside and see what you can spot.
Take off your shoes and feel the tickly grass, the bumpy roots or the squidgy mud.
Roll over a log and see if anyone is living underneath. Make sure you roll the log back to keep the bugs home intact.
Head over to the bird hide and see if you can spot some of our feathered residents.
Visit the geocaching website for the co-ordinates and join in this global treasure hunt.
Hatfield Forest is the best surviving example in Britain of an almost complete Royal Hunting Forest. Where better to find the perfect tree to climb?
There are many species of bird at our special place. From woodland to water they call our special place home.
A well-preserved example of a medieval royal hunting forest, visit Hatfield Forest in Essex with your family and you'll be among some trees that are 1,200 years old.
