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.
