A varied walk with wonderful views throughout, mostly on well-defined paths and tracks, exploring the attractive and secluded valleys of Nanmor and Bwlch y Battel. We start by following field and woodland paths SW along Nanmor before a short stretch along a quiet lane. Soon we pick up an old track which winds gently up through the rough, craggy terrain. We then turn on to a footpath sign-posted for Cnicht, but where those climbing the mountain leave the path to head towards the summit, we continue instead on the broad, grassy right of way through the valley. The path narrows and becomes rougher as it climbs up beside a rushing stream to a shallow, un-named lake and the wild pass of Bwlch y Battel. Here, we divert from the main path onto rougher ground to explore a craggy lttle ridge, visiting the two lakes of Llynnau Cerrig y Myllt and the nearby 463m top. Returning to the main path, we descend steeply alongside a babbling stream to Nanmor. An easy walk, briefly along the lane and then on woodland paths, brings us back to the start.
