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 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.
Have you ever wondered what might be lurking beneath the surface of a pond? Grab a net, head for the Decoy Lake platform and have a dip.
Can you find your way around the forest - there are lots of green tracks and many look the same!
What have you seen in the forest today? Keep a nature diary, so you look back later and recall a good day out
Hatfield Forest is the best surviving example in the UK of an almost complete Royal Hunting Forest. Where better to find the perfect tree?
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.
