Llyn Cau on the Minffordd Path

Highlight (Segment) • Lake

The Minffordd path should not be underestimated. It is a steep climb with alternating stairs, gravel paths, and rough rocky trails. The small lake Llyn Cau is a pleasant break along the way. Don't linger there too long.

View of a mountain lake

Highlight • Viewpoint

Beautiful view of the mountain lake Llyn Cau. It is a 350-meter climb from the car park, past numerous waterfalls and pools, so even if the lake is cold, you will be warm when you arrive.

View of Llyn Cau

Highlight • Viewpoint

Cader Idris is composed of Ordovician sedimentary and igneous rocks. Llyn Cau, which lies at the bottom of the crater-like Cwm Cau, was formed by a cirque glacier during several ice ages. The glacier was once a square kilometre in size.

View of Llyn Cau from Craig Cwm Amarch

Highlight • Viewpoint

From Cwm Cau, the impressive pointed summit of Craig Cwm Amarch looks even mightier than Cadair Idris' main Penygadair summit. It is certainly the most airy summit in the massif and care must be taken when treading close to its cliff edge, which plunges down to Llyn Cau.

The summit is an exceptional viewpoint, with Penygadair to the north, the cwm below and the gentle green of the Tarren Hills to the south.
