There's a cafe in Abergwynolwen, open Wednesday to Sunday that is welcoming, serves good food, and will let you charge bike batteries if you ask nicely

The Penygader summit shelter on Cadair Idris is a super handy, sturdy, stone-built mountain hut designed to protect hikers from the often harsh weather one has to endure here at 893 metres. Located just below the trig point, it provides a comfortable safe refuge from wind and rain, and it has bench seating on the inside. Visitors are asked to keep it clean and tidy.

Great view of the Mawddach Estaury and the mountains beyond, including Cadair Idris. The bridge is 850m long and can be windy in the middle.

Cader Idris is quite an isolated mountain so it has extensive views particularly to the north and south. The views along its east west ridge are also good.

This shelter can get abused, but it a welcome relief to sit a while inside when the weather is bad, which it can be up there.

Cyfrwy may just be a bump in the long ridge that makes up the Cader Idris range, but it boasts a really fine arete with some terrific climbing routes such as 'Table Direct'. The Cyfrwy arete itself is rated as one of the best Aretes in Wales, generally graded Difficult, but with problems such as loose rock to contend with. From above it looks spectacular.

A wonderful place with sensational views both north and south - it isn't always in the misty murk up there!
