TREES DOWN JAN 2022 - A couple of the "Belay" Trees have been blown over during Storm Arwen and are dangling over routes. One currently spanning Murrays Groove. Take care untill they can carefully be trundled over the edge...


One of the best venues in the central belt for those operating in the E3-5 range. (Plenty to go at above and below too). Camby (AKA Thorntons)has had a bit of a renaissance in 2017 with a committed band of locals tidying things up, clearing back vegetation and giving some of the routes a much needed scrub. (There is still much to do....)

Very sheltered, left wall catches evening sun in summer. However, can seep quite a bit over the winter. Very close to the M9 so makes an ideal stopping off point if heading further north or south.


Loose Rock & Dirt:

Thorntons has its fair share of loose rock and dirty holds, although feels more solid than Forth. (Its quarried so fairly new as far as cliff faces go, and there are many larch trees above which drop needles down the routes every autumn). That’s not to say its not a good place to climb but that caution is advised on the less trafficked routes. (Abb it and clean it properly for yourself and the benefit of others if you have any doubt.)

Access Advice

Limited parking - park with consideration

Stock fence and 'no climbing' signs erected but legal right of access stands. If challenged be polite and refer to The Land Reform (Scotland) Act 2003.

Access to Forth Quarry is still open 28/3/23

22/8/23 Someone has cut the barbed wire on the top of the entry fence to make it a more pleasant approach.

The big rockfall around the Nandralone area is now stabilized with the remaining loose sections trundled. Nandralone has been reclimbed as has Cybersex5.

Big Rockfalls in June and July 2020 above Nandralone destroyed half a dozen of routes.

First time in the quarry today and we enjoyed (there are more climbs in my grade S - VS4c here than in the Fourth quarry). Rock is sound but needs a good clean and there are lots of bugs (Tash didn't enjoy them). Could really benefit from removing some of the trees (vegetation in general) to allow some light in to dry the walls after rain. Will be back!!

Youtube view of this venue but not very clear due to the amount of trees.

Worth noting that Spanking The Monkey is more like Font 6c-ish, not Font 7b. It was given E5 6a originally, and English 6a is nowhere near Font 7b. It's actually English 6b, therefore Font 6c-ish. *** and great fun.

'Thornton's Quarry', as it is known locally, is as intimidating as it is excellent. If you are unused to the rock-type it is well worth serving an apprenticeship in the neighbouring 'Fourth Quarry', which is better suited to lower to mid grade climbers, before taking on the challenges presented by such classics as 'Big Country Dreams', 'The Purr-Blind Doomster' or 'Nandralone'. Your efforts will be well rewarded in both the venues!
