This Site of Special Scientific Interest (SSI) is one of Wales's most ancient woodlands featuring a circular walk with eye-catching sculptures and information way stations that tell the story of its natural history and environment.
The area is a natural Limestone woodland of particular importance due to the presence of an extremely rare species of Whitebeam. Ley’s Whitebeam, Sorbus Leyana is only found in one other site. This species can be found on the ledges and cliff areas of the site, along with 10 metre specimens of Sorbus rupicola.
The woodland can be accessed from the A470, on the outskirts of Cefn Coed.
Penmoelallt is managed by Natural Resources Wales.
