6. Run around in the rain
Grab a raincoat and get those wellies on. There's lots of places for you to run around in the rain in the park.
Make a trip down to the wetlands and see the splashes in the pond.
7. Fly a kite
All you need is a windy day. Our meadow by the stables is the perfect wide open space to fly your kite.
Make sure to look up and check nothing will get in the way before your flight begins.
11. Go on a really long bike ride
The Tramway at Calke is nice and flat and perfect for a bike ride. The route goes through tunnels and countryside.
Don't forget to take a drink and a snack in case you need a rest, the route is about 8km in total.
22. Explore inside a tree
Calke Park is full of old trees and some of them have hollows so big you can climb right inside.
25. Make a grass trumpet
There are 600 acres for you to find the perfect blade of grass to make music.
Top tip: make a hole in the grass with your fingernail then position the grass right in between your thumbs.
31. Hunt for bugs
We rank 10th best site in Britain for invertebrates, which live on dead and decaying wood. Check under big logs or stones, in the dead wood pile and under the bark or in the holes in trees.
Don't forget to put the bugs back after.
34. Track wild animals
Follow footprints, feather and fur and track the animals that live in Calke park.
Or look for other signs - badgers love making a mess in front of the house hunting for grub.
44. Go bird watching
Find our two bird hides next to the deer park and in the wetlands. Keep silent as a mouse and watch the birds at play.
Take a camera and see what you can spot. Rare turtle doves have been seen in the hides before.
