Some 300 feet lower than the nearby Arenig Fawr, Moel Llyfnant is often neglected in favour of its higher neighbour, but it is well worth walking in its own right. The mountain is usually approached from the north, or from Arenig Fawr by crossing the broad bwlch between the two mountains, but today we take an unusual route from the south, making a circuit by following a gently rolling ridge back over Moel y Slates and Foel Boeth. Our route begins by heading along a lane, turning off by Hendre-blaen-Lliw to climb across rough pastures. The gradient steepens as we turn up a broad, grassy gulley, emerging not far from the 751 metre top of the mountain. Extensive views of the nearby Arenig Fawr and more distant mountains await us at the summit cairn. We descend to the NW, traversing a boggy area before making the short ascent to Moel y Slates. Turing south, we continue along the remote, undulating ridge to return to the start.
