The loop from Llandrillo going anticlockwise is very steady and pleasant. But be prepared for substantial bog trotting in the central part of the valley passing the area marked as Gwern Wynodl. Even with newish goretex boots, we came away with wet feet. Good boots and gaiters, or wellies for that section highly recommended. Return section (first section if doing it clockwise) is also pretty boggy in parts. It also seemed like a bit more of a slog doing it clockwise.

Once thought to be the highest summit in the Berwyn Range, Moel Sych is actually the third highest behind nearby Cadair Berwyn's main and north summits. Still, at 2,712 feet (827 m) in height, it affords terrific views across this quiet part of upland Wales. Interestingly, the summit is the meeting point of the historic counties of Montgomeryshire, Merionethshire and Denbighshire.

At 2,070 feet (630 m), Moel Fferna is the highest point in the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty. However, it belongs to the wider Berwyn Range, which reaches its apex on Cadair Berwyn to the southwest. It's possible to link both on a long walk, along with other summits in the range. The Dee Valley is a good base for hikes to Moel Fferna, with plenty of accommodation options and places to eat and drink.
