ROUTE DESCRIPTION
Starting from the Tyn-Y-Cornel Hotel the route follows a country track along the north side of the stunning glacial ribbon lake, Tal Y Llyn, before entering the Cadair Idris National Nature Reserve.
You will run through the tranquil woodland of Dol Idris and then up steeply through the wooded gorge. As you ascend out of the trees you will clasp glimpses of the stunning glacial lake Llyn Cau to your left. You will continue your ascent towards Mynydd Moel before traversing west and ascending to the summit of Cadair Idris, 893m.
The section between the 4km and 6km mark involves steep ascent. The most challenging underfoot terrain is just after the summit of Cadair Idris.
Once off the rocky terrain of the summit your descent will follow the established Pony Path before turning south west down towards Tyn Y Fach and Mary Jones' Chapel. You will then follow a beautiful section of the Mary Jones walk before traversing North East through tranquil woodland tracks and back to Tal Y Llyn and the Tyn Y Cornel Hotel for some well earned rest.
