Lying a little to the south of the most popular Snowdonia peaks, and being somewhat lower, the Moelwyns attract considerably fewer visitors. They do, though, provide for exhilarating walking and wonderful views, with the added interest of slate-quarrying remains scattered over the hillsides. Our walk starts by ascending the southern side of Cwm Croesor, past the Croesor Quarry, to the little lake of Llyn Croesor. From here we head up the grassy ridge of Moelwyn Mawr to reach the summit trig point at 770 metres. The spectacular views include the ridge of Cnicht, Snowdon, Yr Aran, and Y Lliwedd. You can also observe no less than fifteen lakes nestled within the landscape. We next head down to Craigysgafn, the craggy ridge between Moelwyn Mawr and Moelwyn Bach, before descending a steep, rocky path to Bwlch Stwlan. Continuing over the bwlch, another short climb takes us to the summit of Moelwyn Bach (710 metres) with further superb views, particularly west towards the Lleyn Peninsula. An easy descent along the broad west ridge of the mountain brings us down to a quiet lane, for just a short walk back to the start.
