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.

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.

The walk to bag the 633m summit of Tarrenhendre is not as popular or busy as those on its more famous neighbour on Cadair Idris, but you do get a nice, lovely, scenic and historic walk out of it. There are nice views to be had from the summit too. If you want to add another hill to your tally, then you can easily extend your walk to take in nearby Tarren y Gesail.
