Short but beautiful and well worth visiting. Amazing that this fall use to power the once working mills above. A lovely peaceful and beautiful stroll was had here. The upper bridge looking down to the falls offer picturesque views whilst the old mill building were cool to observe but sad to see rotting away in a beautiful valley

The reservoir was originally built in 1924 to supply water for the hydro-electric power station in Dolgarrog, which in turn powered an aluminium smelting works. This power station is still operational today. Coedty Reservoir is historically significant due to its involvement in the devastating Dolgarrog Dam Disaster of 1925. The failure of the Llyn Eigiau dam, located upstream, led to a surge of water that also breached the Coedty dam. This resulted in a catastrophic flood that swept through the village of Dolgarrog, causing the loss of 16 lives. Coedty dam is a "balance tip" dam, meaning water flows from it automatically when it reaches high levels. This excess water flows into a spectacular gorge below, which is used by outdoor pursuit groups. However, gorge walking here can be dangerous due to the sudden releases of water.

The sobering part was reading how they thought it was safe after hearing the church bells. They weren't, it was the church getting swept away!!!!

The worst part of any hike ever. I had to carry on going up, creating my own path, through trees, scrambling up mudfalls, rock climbing with no ropes. it's all collapsed.

Just a little slice of paradise. Was the only person there, I hadn't actually seen a person all day. So..... a bit of free swimming was required

A series of waterfalls in the Crafnant river, falling around 8-metres at their tallest point. The falls were formed in the last ice-age, when the area was glaciated 200,000 years ago. The glaciation formed a number of the falls in the area, as well as hanging valleys. The river eventually flows into the Conwy river, further downstream.

You can expect varied terrain, from well-trodden paths through ancient woodlands to steeper, more uneven sections, especially around the gorges.
