Quieter than Penygadair but with equally impressive views. Great for a spot of lunch.

Just below the rocky summit stands a sturdy stone hut. It is a modern version of a 19th-century hut that became famous through an old lady who climbed to the summit early in the morning and offered a cup of tea (paned o de) to everyone who passed by. "Paned o De" is said to be the name of this shelter. (Snowdonia active)

According to legend, Cader is named after a giant called Idris Gawr. 'Cadair Idris' means 'Chair of Idris' in English, while 'Cader' can also refer to an ancient fortress. The place is known as Cader Idris rather than Cadair, but both names are used. The most famous local fable is that if you spend the night on the mountain, you will go mad or become a poet.

It is worth the effort. At the top, you enjoy a beautiful view in all directions. It cannot be captured in photos.

This last climb is very difficult due to the many loose stones and rocky ground.

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.

If you smile sweetly you don’t have to pay. There are also public toilets just after this.
