Get out into your local woods (or even the garden) and try and build a den. Start out with a frame made from branches, and then cover with smaller sticks and leaves to create a cosy hidey-hole. If the kids can lie down in it without it falling over, it counts as a success.
There are still a few wild fruits around, so head out with a small bucket and look for wild blackberries or other autumn fruits.

Pick some points - around the garden or park for smaller children or a larger area for older children, draw or print a map and see who can make it around the route in the quickest time. If you are feeling sneaky, remember that the fastest route between two points is not necessarily a straight line if there is more difficult terrain or a landscape feature such as a river in the way.
Use an upside-down crate or pile of logs and cover it in some fallen leaves to encourage a hedgehog to hibernate in your garden (see how to build your own house here). It's best located in a quiet spot out of drafts, but don't worry about filling it with bedding - hedgehogs prefer to do that themselves.
With earlier nights it's the ideal time to go out star gazing. Ideally, you need a clear night with few clouds, a new moon and a place as far from artificial light as possible. It can take quite a while for your eyes to adjust to low light levels, so allow at least 10 minutes. It can become surprisingly cold when you are not moving, especially if you are lying down, so bring warmer clothing than normal and a waterproof rug or tarpaulin to lie on.

Collect conkers, drill a hole and thread one per string, and then see which one survives. Coating in varnish, soaking in vinegar or baking them is cheating! If you get really good, you may even be able to take part in the Conker World Championship!
As trees lose their leaves it can make climbing easier, so choose one with easy to reach branches and get climbing. If you want to go higher, many national parks have tree climbing events where safety ropes and skilled instruction are available.
