Harrison's Rocks

Southern Sandstone

Beautiful and unique rock architecture which provides challenging climbing across the grades is the stand out feature of this incredibly popular South East crag. The intricacy of movement its routes require and stunning woodland setting transport you into another world and it’s easy to imagine you’re a character in a folk tale long ago as you wander around below the crag. As with all southern sandstone, leader placed protection cannot be used because of the soft nature of the rock and whilst this might be a little unusual for us trad obsessed Brits, you will quickly get into the top-roping zone and come to appreciate the fine climbing on offer. 

Crag information
Climbing Area: London & South East Rock Type: Sandstone
Importance: National CRoW Land: Yes
Ownership: BMC Owned No. of Routes: 588
Within National Park: No Year Developed: 1926
Grid Reference: TQ532355

Harrison’s Rocks are owned and managed by the BMC for the benefit of climbers and the general public for recreation on foot. The rocks are well-equipped with bolts for top-roping and as with all southern sandstone crags the rock is very soft meaning leader placed gear cannot be used here as it will damage the rock. The only acceptable styles of climbing are top roping using a well rigged system that will not damage the rock with moving ropes, or if you are confident of your abilities - soloing. A group of volunteers periodically load-test the bolts, but there is no way to guarantee their strength and as with any crag all climbers should make their own assessment of fixed equipment before use.

Birchden Wood (the woodland surrounding Harrisons) is owned by the Forestry Commission and has been dedicated as open access land. The fields to the west of the Rocks are private property. Any trespassing strains the good relations between climbers and our neighbors - if you are in charge of a group please make sure that your party is aware of this.

Isolated Buttress access advice

The large block on the mainland opposite Isolated Buttress which was used to step across the gap has been removed due to it becoming unstable and dangerous. At the Sandstone Open Meeting in May 2015, considerable local opposition was voiced to the idea of construction of a bridge across to the pinnacle (to allow access from above). The Harrison's Rocks Management Group are monitoring the situation to help inform a decision on a long term solution. 

In the meantime, please avoid abseiling or lowering off from routes on the Isolated buttress as this will increase wear to the fragile rock.

Various methods can be used to access the pinnacle and setup your ropes including soloing and being belayed across from above but these will be too risky for many climbers. The method which offers the most protection requires a very long length of rigging rope and is described in this short film on BMCTV or below:

  • Attach a locking carabiner to the end of your rigging rope
  • Clip your climbing rope through the locking carabiner at it's mid point 
  • Throw your climbing rope over the pinnacle to another climber on the ground 
  • The climber on the ground gently pulls both ends of the climbing rope until the rigging rope screwgate is hanging over the lip of the crag and flicks the rope into the right position to protect a route 
  • The climber on top of the crag ties off the rigging rope to the set of bolts on the main crag (or a suitable tree), leaving the locking carabiner hanging over the lip of the crag and the climbing rope not contacting the rock when it moves
  • The first climber up then re-rigs the rope for subsequent ascents using the bolts on top of the Isolated Buttress, ensuring the moving rope does not come into contact with the rock
  • All climbers then climb the route(s) and downclimb either the route they climbed or an easier alternative, rather than lowering off or abseiling

To retreat from the pinnacle at the end of the session: 

  • The  last climber to top out re-clips the climbing rope through the long rigging rope attached to the bolts on the main crag 
  • All other rigging equipment is removed from the bolts on top of the Isolated Buttress
  • The climber then down climbs a route with a belay rather than abseiling or lowering off
  • Once back on the ground the climbing rope can be pulled through and the rigging rope retrieved from above

Parking and Approach


The Forestry Commission have installed a pay and display machine to cover the costs of running and maintaining the car park and toilet block. Please make sure you pay and contribute towards keeping this valuable service available to the public. The machine takes coins only and charges are as follows:

  • Cars: £1/hour, £4/Day, £6/24 hours or a 'Discovery Pass' which allows unlimited parking for a year from the date of issue. (This will only be available for cars).
  • Minibus (up to 17 seats): £2/hour, £6/day, £8/24 hours
  • Coach: £3/hour, £10/day, no overnight stays


Camping is also owned and managed by the Forestry Commission and should paid for using the pay and display machine - current prices are £5/night for adults and £2.50/night for children. Please make sure you pay for camping and follow the below rules to ensure the campsite is kept open by the Forestry Commission:

  • Use of one of the 16 marked pitches is the only acceptable place to pitch tents - if you arrive and find the campsite full, please don't be tempted to pitch your tent elsewhere in the surrounding woodland
  • Campervans in the car park are not allowed
  • Do not leave tents pitched if they will not be occupied that night
  • Discovery Passes only cover parking - not camping

There are a number of other campsites nearby, and these may also be more approriate for families or those needing more extensive facilities: 

  • Camping & Caravanning Club site, Crowborough (www.campingandcaravanningclub.co.uk/campsites/uk/eastsussex/crowborough/crowborough)
  • Manor Court Farm, Ashurst (www.manorcourtfarm.co.uk/camping)

CRoW Information

Open access land, designated under the Countryside & Rights of Way Act (2000) give area access rather than linear access as provided by public rights of way. It also gives a legal right of access specifically for climbing, as well as walking and other quiet recreation on foot.

Please bear in mind however that the landowner still has the right to restrict access for up to 28 days per year (often used on public safety grounds for shooting in moorland areas), and can also apply for longer term restrictions with Natural England (such as bans on dogs, or regular restrictions during particular times of year). It is important to check for these restrictions regularly as they can be added at short notice – all details for open access land in England can be found on Natural England’s website.
