The reserve at Coed Ganllwyd includes a steep, wooded gorge with tall waterfalls. The main attraction for many is the spectacular Black Falls of Rhaeadr Ddu on the Afon Gamlan. The forest is part of a wider Site of Special Scientific Interest (SSSI) and is part of the Coedydd Derw a Safleoedd Ystlumod Meirion/Merionnydd Oak Woods and Bat Sites Special Area of Conservation (SAC). The wet climate that nourishes the falls also creates the humid conditions in the gorge, making it the richest place for mosses in northwestern Europe. The rocks and tree trunks are decorated with the green and gray growth of these simple plants. The trees largely escaped felling during two world wars and are an excellent example of the ancient oak forest of this part of Wales. (VisitMidWales)
