April 12, 2026, Tarren Hendre Summit

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.

A former slate village with a certain type of raw beauty, Corris is a little tourist honeypot. It is set within the Dyfi Forest and boasts a few attractions such as a craft centre, a centre for alternative technology, along with a narrow-gauge railway and museum. Ohhh did I mention bike trails? It has a never ending supply of them!
