The peaks on the Llyn Peninsula such as these are often ignored by walkers, who prefer the higher mountains in Snowdonia to the east. However, although they may not be as high, you start from close to sea level and in fine weather you can have views over four countries (Wales, England, Eire and Isle of Man).

Attempted this walk today. Route up somewhat overgrown, but passable. Good going around the peaks with stiles appearing where needed. As far as I could see, the path mentioned from Waymark 7 down the steep valley just does not exist. I headed down anyway still not finding anything faintly resembling a path. Heather covered rocks gave way to steep loose scree, then shoulder high bracken and half inch thick brambles. It took 2.5 hrs to reach Waypoint 8 including torn trousers and numerous deep bramble scratches! Verdict - don't even consider that descent route. Note for Dan - this route needs a proper review, at least from Waymark 7 to the main road. It could be dangerous for a novice on the hills. Malcolm.

We also found this an extremely enjoyable route, however I would emphasise that even in good weather the descent may appear daunting to those who are not used to this type of very steep ground

Our party of 10 enjoyed this walk however it was far more demanding than we anticipated (most of my walking experience is on the Brecon Beacons) and we had to abandon the route and find an alternative escape route. Firstly this is not a good walk to take dogs on. At point 3 - stiles were not really discernable however the walls were easy to climb over without risk of personal injury or damaging the wall, getting a large dog over is another matter! The rocky outcrop at point 6 Gyrn Ddu and surrounding area is very slippery when wet and the rocky ground full of holes for the unwary foot or paw. We attempted to descend the very steep valley as described but abandoned the attempt 100m before point 7 just before a place of no possible return. Much of the walk had been in clear sunshine however rain and mist reduced visibility here to less than 30 metres plus very slippery and a bit scary.
