Approach: Drive through the village of penygros heading for talysarn. follow the road thru talysarn(with a left and a right-please drive slowly!) till you end up at the quarry entrance.Beware divers in landrovers ragging up the path.

The first hole on the left is the car dumping pool,who knows how it got this name!.The very steep wall at the back stands out as a project for some strong young devil.

Away down to the right is a pool mostly used by herons and ducks that yields some great summer deep water soloing action (inflatable dingy required!) but can u name another slate DWS venue? (dalis hole excluded)

The main pool of dorethea is the site of Trevs Slab and the first new route to be posted in this section.

Hidden up on the left as you enter the quarries from this side is Unknown hole and Gallt y Fedw These areas have massive potential for new routes To access these take a left through a gate 40m down the main road into the quarries,walk up the hill till you can access an obvious level running off to the right,walk along this level and you will come to Unknown hole, after the spike at the head of unknown hole descend down the scree a level and you will end up at Gallt y Fedw.

If you choose to check out these areas please respect any half equipped or cleaned ready for bolting lines.
There is plenty of slate in the dorethea area of nantlle,just watch out for the ninja frogmen.
