At the start of the path, you walk past a mountain stream. The water flows down past all sorts of rapids and a few small waterfalls. You can admire them here.

A set of double falls, upper and lower. Both are quite tricky to photograph, the upper falls being the more precarious as you have to look over an edge to see the full drop. The lower falls are easier as you can get a low Point of View and hence get the flow of the water past you. These falls are only a few hundred yards up a well marked and obvious path, large car park on the main road at the bottom of the roadway.

I started the opposite way of the route, going to the summit of Y Garn the shortest way. It was better. Starting the long way around is too tidings even going down. Be prepared to get lost without Komoot and the path they show (it’s like a compass) because the paths are hardly visible in places. There is an old gold mine worth passing by. The views from Y Garn are well worth all the sweat.

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)

Rhaeadr Du (Black Falls in English) is a 20 meter waterfall that plunges over 2 steps onto the fast flowing Afon Gamlan as it passes through the Coed Ganllwyd National Nature Reserve at the spectacular Coed-y-Brenin Forest or Forest of the Kings . At the waterfall, large stone steps lead to a kind of viewing platform that offers beautiful views of the falls. Visitors are advised to exercise caution as the area can be very slippery and dangerous in wet weather. (Snowdonia guide)
