About this Route
The Minffordd Path is the shortest but steepest of the main routes to Penygadair, the 893 m summit of Cadair Idris. TrailTrack’s calculation of the supplied GPX gives an 8.6 km out-and-back with 887 m of ascent and a 3h 12m estimate. The route starts at Dôl Idris, climbs beside the stream through ancient woodland, passes Llyn Cau and continues steeply to the ridge before reaching the summit.
This is a strenuous mountain route with sustained stone steps, steep rocky ground and exposed edges. The return follows the same line, and the descent needs particular care when the rock is wet or visibility is poor. The official visitor guidance recommends allowing about 5–6 hours for the Minffordd Path, so treat the GPX time as a planning estimate rather than a deadline. Carry a map and compass, check the mountain forecast, and do not attempt the route in winter conditions without the necessary skills and equipment.
Llyn Cau is a useful landmark on both legs, but the route above it crosses steep ground beside cliffs and should not be followed blindly in mist. Penygadair has several paths leaving the shelter, including lines towards the Pony Path and Mynydd Moel. Take a bearing for the Craig Cau ridge before descending. The woodland steps remain steep all the way to Dôl Idris, so keep time and concentration for the final kilometre.
The Minffordd Path earns its height quickly, with Llyn Cau below and Cadair Idris opening out above the ridge.

Route Waypoints
Begin at the Eryri National Park car park and take the signed Minffordd Path into the woodland. Check parking and toilet arrangements before setting off.
Climb the many stone steps beside the stream through Coed Cader’s ancient woodland. The path briefly eases after leaving the trees before the steeper mountain section begins.
The path reaches Llyn Cau beneath the cliffs of Craig Cau. Continue on the signed Minffordd route and climb steeply above the lake towards the ridge; take care on wet stone and near exposed edges.
Gain the ridge near Craig Cau and follow the clear mountain path towards Penygadair. Exposure to wind increases here, and cliff edges are hazardous in low visibility.
Penygadair is the 893 m summit of Cadair Idris and has a stone shelter. In mist, confirm the correct return line before leaving—the summit area has several paths and it is easy to descend towards the wrong valley.
Leave the ridge on the same steep line above Llyn Cau. Keep away from cliff edges and slow down on loose stone.
Re-enter Coed Cader and descend the long flight of stone steps beside the stream. Wet leaves and polished rock need care.
Retrace the Minffordd Path to Dôl Idris. Descend slowly on the steep stone steps and rocky ground, especially above Llyn Cau and when surfaces are wet.
Essential Tips
Low cloud can obscure the summit paths and nearby cliff edges. Carry OS Explorer OL23, a compass and a backup navigation method, and confirm the Minffordd return line before leaving Penygadair.
The return uses the same steep route. Wet stone, loose material and tired legs increase the chance of a slip, so allow extra time and keep a controlled pace on the descent.
Check the mountain forecast before setting out. The ridge and summit are exposed to strong wind and heavy rain; turn back if visibility, wind or underfoot conditions make continued progress unsafe.
Dôl Idris is a pay-and-display Eryri National Park car park with toilets and card-only payment. It can fill at busy times, so arrive early and check the current parking information before travelling.
