Restricted Access

July 2018 - Major rockfall affects Lost World/Mordor areas. In recent years there have been significant and massive rockfalls (hundreds if not thousands of tons of rock)  in this area, and in early July another significant rockfall occured here, that would have wiped out anyone in this area at the time. There is further significant and unpredictable rockfall likley here and it would be prudent to avoid this area. 

The Upper Dinorwig quarries are mainly owned by First Hydro. Access for climbing or any access away from the designated footpaths is not permitted by the landowners, due to liability concerns. However it's rare for climbers to be asked to leave and in general it appears that if climbers keep a low profile, avoid damaging fences, do not interfere with any of the power station buildings or apparatus or any of the historic structures within the quarry that climbing is possible. Access to the whole of the upper quarries have become especially sensitive in recent years and climbers should not gather in large numbers, especially at Dali's Hole area. Bolts have been removed from Dali's Hole by a local climber (late 2010) who was concerned that continued use of this venue by large groups of climbers would jeopardise access to the whole site. There have also been a number of reported altercations between climbers and First Hydro security staff over the years at this venue.

BMC advice remains unchanged - the landowners do not give permission for public access (including for climbing) away from the public paths. Please do not damage fences or signs and if accosted by security staff, please be courteous and report any issues to the BMC.

Seasonal Restrictions

Reason: Nesting Birds

A fence has been errected across the base of the Dali's Hole area to deter access to this area due to liability concerns by First Hydro. Access to this area is especially sensitive at this time and security staff have been reported to be asking climbers to leave this area.


Rockfax Description
A superb pitch with unusual moves on excellent slate. From a block, reach left to a ledge on the left. Swing left and gain the ledge on the left of the arete. Continue up the arete with difficulty until the angle eases. Easier climbing leads to a delicate finish. © Rockfax

UKC Logbook Description
On a new level/sector I would like to call "Ayers Rock" (as it is not quite as far up as Darwin).
The easiest approach to find is from the Darwin Level. From near the concrete blocks on the edge of the Darwin plateau about 100 m before the big gated hydro tunnel descend diagonally L (facing out) to an old horizontal track (could reach this point by traversing along the next level down). Follow the track towards a big boulder. Pass below this and continue across grass and scree to a boulder field on the "Ayers Rock" Level. Descend the boulders and traverse to a nice grassy spot near a ruined hut (fabulous views of the Australia levels). The route starts at a block leaning against the R side of the prominent arete a few m up the scree slope beyond the hut.

A superb pitch with unusual moves on excellent slate. From the block gain a ledge on the L of the arete. Continue up the arete with difficulty until the angle eases. Easier climbing leads to a more delicate finish. (10 bolts + 2 bolt lower off with rings).
