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 Minffordd Path (Welsh: Llwybr Minffordd) starts on the south side of the mountain, near the glacial lake Tal-y-llyn. Hikers following this route climb past Llyn Cau and along the edge of Craig Cau (a rock face) to Penygadair. The route is 4.4 kilometres long and includes two ascents of over 300 metres. (Wikipedia)

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.
