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.

Tarren Hendre's grassy summit is the southernmost 2,000-foot (610 m) peak in Snowdonia. This position gives it unique views into mid Wales towards Plylimon and north towards the great mass of Cadair Idris. It's also the first summit visited on the Snowdonia Way Mountain Route.

December 13, 2022, Tarren Hendre Summit

Tarrenhendre at 633m is one of the tops in the Cadair Idris mountain group. It's a big grassy summit with a steeper top and a cairn. It's a good run partly due to its loneliness, you probably won't see anyone and you can have a proper wild adventure!

The Bearded Lake or Llyn Barfog is a pretty mountain lake below Mynydd y Llyn. It's fringed with water lilies and other plants which may explain its name. Legend has it that once a monster lived here, terrorising the local people. King Arthur came to rid the area of the menace, lassoing the monster with magical chains and dragging it out of the lake with his horse Llamrai. You can even see the horse’s footprint in a nearby rockface - Carn March Arthur.

At the start of the Minffordd path there is Dôl Idris, a small lake. There's a nice gentle stroll around it for those not wanting to venture too far vertical, or a great addition to the start of the long climb ahead.
