Moel y Gest can be climbed by approaching it from the south, starting from the unclassified road from Porthmadog to Black Rock Sands. This crosses pasture fields before reaching steeper slopes with gorse and bracken. There are a number of interconnecting paths on the slopes. The summit is rocky with rough grass and boulders, and there is a cairn and a path along the ridge. Other routes up the hill are available from the northeast, north and elsewhere but there seems to be no main path.
