High Rocks

Southern Sandstone

The region's hardest (and best?) crag. Strong lines and tough, fingery challenges as well as a wealth of delightful struggles in sandstone chimneys. There has been a history of access issues and bans at the crag due to climbers not following the agreements made with the landowner - please make sure you follow the conditions below and do your bit to keep access to this fantastic crag open.

• Climbing will be available on weekdays when High Rocks is open. Some weekends are possible, especially Sundays. Availability will be made clear at pre-booking.

• There will be no access for climbers turning up on the day without pre-booking.

• When climbing, please respect High Rocks’ staff requests to have your name checked against the day’s list or move to a different climb if requested.

Please note the following:

Practical information.

High Rocks is a different climbing environment to Harrison’s, Stone Farm and Bowles Rocks. It is a natural crag with only limited man-made additions. The only belay bolts are on the Hut Boulder.

For all other climbs, natural belays must be used. There are numerous trees ideal for the purpose, but many are set back from the crag edge. You will need a length of static rope to build a belay. This should be a minimum of 10m in length but it is worth taking a longer or a second length where a ‘Y’ hang is required. Slings are of limited use. Chose another climb if you cannot ensure that your karabiner hangs over the edge of the crag and that no moving ropes come into contact with the rock. An additional rope/handline is advised for retreat from the Isolated Boulder.

 As the name suggests, some of the climbs are high, maybe 12m or more at the north end of the crag and may require a longer than normal climbing rope.


Apart from the main crag, there are various Isolated Buttresses at High Rocks – each has its own character and access method. The three main isolated buttresses are:

Matterhorn Boulder – access by an easy climb on the ramp at the rear to fix a belay, mainly from the overhanging tree branch. Downclimb the ramp when you finish your climb. Do not lower off from the route you just climbed.

Isolated Boulder – Initial access by soloing a route. Ordinary Route (4a) or Simian Progress (5a) are probably the easiest. Once on top, set up the rope and belay for your selected climb. Ensure your karabiner hangs over the edge of the crag. There are a few smaller trees and a large one in the middle. In order to get back down, arrange a rope to hang down Ordinary Route and back climb using the rope as a handline for assistance. Do not lower off from the route you just climbed.

Hut Boulder – There are five pairs of bolts above the popular climbs on the Hut Boulder and these should be used in pairs (there are no interconnecting wires) to build a belay. There is also a legacy iron loop. Whilst this had proven well-fixed at bolt tests, its provenance and overall condition is not known. Hang your karabiner over the edge and ensure moving ropes do not come into contact with the rock. Initial access may be made by soloing a route (Crack Route 4c is an obvious contender). Alternatively, throw a static rope over the Hut Boulder from the mainland. There are a pair of bolts on the mainland near the top of Easy Crack for tying off to. Either use a Shunt or similar protection device to climb Crack Route (4c) or attach a karabiner and climbing rope to the other end of the static line and tie off in a position where Crack Route (4c) may be climbed on top-rope to gain access to the top of the boulder. Ideally, Crack Route should be down climbed when finishing a climb. Do not simply lower off from the route you just climbed.

As with all southern Sandstone crags, please follow the BMC Sandstone Code of Practice.

If you are unsure about setting up belays, read the guidebooks or ask other climbers.

High Rocks, (like other Southern Sandstone crags) is a finite resource, not a climbing wall – please do not treat it like one. Respect the rock, minimise the amount of chalk you use. When you finish your climb, untie and walk back to the ground. Do not lower off.


  • Admission charges: High Rocks charge an entry fee to anyone wanting to visit the rocks. For climbers, this is £12 per day
  • Respect ground staff: good behaviour is essential to continued climbing access at High Rocks. Please be polite to any staff you meet in the grounds and follow any instructions they give you.
  • High Rocks Functions, including Weddings: Climbing will not be allowed during weddings and other High Rocks functions that use the rock outcrop. Where climbing is allowed, every effort must be made to avoid causing an impact on High Rocks events. If you are asked to move by a member of staff, please do so immediately.
  • Chalk: is an unwelcome intrusion for non-climbing visitors to the rocks. Keep any use of chalk at High Rocks to the absolute minimum and ensure you brush off any excess chalk once you are finished or avoid using chalk altogether.
  • Bouldering: is banned by the landowner, as are boulder mats - only top roping or soloing is allowed.
  • Rock erosion: as with all crags on Southern Sandstone, the very soft rock can be easily eroded. Ensure no moving ropes are able to contact the rock by extending top ropes over the edge of the crag with static rope or slings. Clean the soles of your shoes before stepping onto the rock – any sand or dirt on them accelerate erosion of footholds and make the climbing harder.
  • Shouting and bad language: don’t use it at High Rocks. Children and other members of the public all visit the rocks as a place of peace and solitude. Please be sensitive to these other visitors.
  • Litter: as with any other crag, please take all litter home with you.
  • Sandstone Code of Practice: all climbers on southern sandstone should be aware of this code, which gives advice on how to reduce your impact on to the rock. It can be found at: https://www.thebmc.co.uk/access-launch-updated-version-of-the-sandstone-code-of-practice

I emailed the manager on 2018-06-14 to ask about access and was told:

Regrettably all climbing has been suspended by our insurers until further notice. We will keep the BMC informed when and if this changes.
