Nice hills and views of the surroundings from them. In winter, the trail likes to be muddy.

The Clappers is a fascinating clump of trees on top of what was an Iron Age fort (!) The ascent is easy, but hikers should note that the descent (down a perilously steep set of makeshift wooden stairs) is challenging in the wet.

Deacon Hill (172m), from which there are stunning views in essentially any direction (as long as you don't stare at your boots) is a Site of Special Scientific Interest (the summit area is rich in plant species, and there are birds here such as buzzards and numerous species of butterflies, too). There is a bench to sit on as well. The hill is a gorgeous place to be and marvel at the beauty of the world.

This nature reserve is a really stunning part of the world! Beautiful far-reaching views of the countryside from up here, fantastic green, grassy chalk hills, and also gorgeous spots along Barton Spring within the wood. Beech woodland, wild flowers, weasels and hares here and there. What more could you possibly want?

A fantastic forest walk with amazing views from above over the Chilterns, particularly towards the north. On the way, you will encounter a memorial by W A Robertson, who gave this area to the National Trust in memory of his brothers who died in the Great War. A great and enjoyable steep set of wooden stairs by the end of this stretch, too, as you rejoin the Chiltern Way.
