Warm-up Alley All Bouldering 17 routes in boulder field

Please respect the local ethics and at all times, look after the environment. This means definitely no chipping, use your wire brush sparingly and only on the holds that you are using, leave the trees alone (it is often possible to pull them aside temporarily if they are covering a problem), and of course take out everything that arrived with you. The rocks are covered in beautiful paint-like lichen that for the most part doesn't interfere with climbing. If you need to clean lichen from a problem, remove only what is essential, and preferably as little as possible.

Harvey's has innumerable very high lines, such as Spenser's "Deliverance" and "Walk The Line". Despite this, Harvey's Marbles remains a bouldering crag and therefore no bolting is allowed. Top roping is fine if you want to do something that is too high for you to boulder.

This is private land and we are very lucky to have permission to access it please follow some simple rules:

• No bolts
• Keep to the walking trails where possible.
• Take all rubbish with you.
• Protect the environment; try to leave as much of the moss growing on the rocks as possible.
