This tree carving is masterful and the size of an adult. Its remote location imbues an aura of mysticism.

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

A dead tree has had a carving added to it. At Christmas 2023 the trees here were decorated.

Rocky, narrow, but very scenic, descent into the woods with some glorious views across the Taff Vale toward Nantgarw.

Super cruisy fire road climb to the top of the trails. On the way up you can check out all the trail options jumping off to the sides.

The road to the South of Garth Mountain is named the "Route Des Alpes" on Google maps. I'm thinking it isn't genuine, but I like it! The views from the footpath climbing up off the road are fantastic on a clear day.
