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.

Here you can, after the crossing (ladder), go to Mynydd Moel (up) or to the Dol Idris parking (down).

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

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.

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.
