Beneath (2½m) Halfway station (1600ft) on the right is the deep valley of Cwm Brwynog, with its amphitheatre of cliffs. The bridle path is recrossed just beyond (3¾m) Clogwyn (2550ft) and lookind down you see the gorge of Cwm Glas Bach and glimpses of the Pass of Llanberis. Curving to the right ascend a slope above the cliffs of Clogwyn-du'r-Arddu, quot;the black precipice", with its tarn at its foot. Next you cross the Snowdon Ranger Path (3200ft) and climb the relatively gentle declivity of the saddle - 5m . Snowdon summit station lies just below cairn of Y Wddfa.
