Coming out of the woods on the Chiltern Way here will provide you with an absolutely stunning view of the countryside down below and, right next to you, of the Knocking Hoe National Nature Reserve. This is chalk grassland, supporting rare plants such as moon carrot and field fleawort. There is a viewing platform nearby with some information about the reserve too.

An outstanding view from Noon Hill, part of Pegsdon Hills Nature Reserve. You may spot some grazing livestock up here. As well as birds of prey gliding on the thermals.

The village of Great Wymondley is actually smaller than neighbouring Little Wymondley, owing its title to the fact it was there first, rather than its size. Its parish contains two scheduled monuments: Wymondley Roman Villa and Great Wymondley Castle, the earthworks of a former motte and bailey fortress. After a hike in the Hertfordshire countryside, the Green Man pub is a good option for a refuel.

A local legend! Steep and straight, you'll know you've been up a hill! Great views from the top though.
