1 As you'll see from the information board, there are three marked trails here: red, blue and yellow. You can choose your own route or follow this one, which is a combination of the red and blue trails.
2 Head for the track at the far, right-hand corner of the car park, near the kiosk, and follow this path, part of the London Loop, through a metal gate. Take the right-hand fork, cross a footbridge over a ditch and follow the path uphill along the central path ahead.
3 A few paces further on, the path swings to the right and then descends, crossing another path and a footbridge before dipping and ascending once more. Follow the path to the right as it crosses another footbridge. About 50yds (46m) further, at a wooden post marked red, turn left along a path that later narrows and descends gradually. Here you will see large clumps of rhododendron.
4 At a clearing leading down to an embankment, turn left. A little further on you'll pass more wooden posts, marked blue. As the path rises again bear sharp left at another post and turn right down steps and over a brook. Continue ahead as the path rises to another post and some more steps leading to a footbridge.
5 The path passes three more posts and after the last, it rejoins the London Loop. The field to the south of the entrance was once a hay meadow, used for feeding some of London's large number of horses. At the footbridge, turn right along the limestone scalpings track back to the car park.
