A solid limestone cave with fantastic views overlooking the Avon Gorge. Hard eliminate bouldering mainly on pinches or sloping holds with thumb catches. There are many variations and eliminates to be had. Please note, any stars given to problems here are "gollums stars" and serve only to differentiate between problems. Obviously eliminates are never worth any true stars.
The numbered problems feature in the guide produced by the late Ian Hill. A reproduction can be found in the esoteric bouldering guidebook (no longer available on the Climbing Academy website).

Gollum's is not easy to find. The easiest access is from the junction of Percival Road and Clifton Down. Take the right turn up the tarmac footpath that gently curves round to the right as it goes uphill away from the road. Walk straight on up here for 120 m to where a dilapidated metal fence appears on the right hand side of the footpath. Here drop down the steep earth bank on the right and turn left onto an earth track. Follow this for 15 m to a concrete block. Turn right steeply downhill for 30 m and then down and left for another 25 m to a large block of limestone lying on the left of the path. You should be able to see the buttress ahead from here - follow the track left and down again for 20 m. This takes only a couple of minutes from the road.
