Over the bridge from the town and to the left, or park at the Library and walk along the river to the bridge. Take care The circle was erected at Llanrwst in 1950 for the 1951 National Eisteddfod. It consists of a circle of 12 stones with 2 outliers, using unhewn natural stones from near Llyn Ogwyn. Thought to have been reused for the 1989 National Eisteddfod.

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

Approaching from the north it is a slog on the bike but nothing technical. With the right gearing and fitness it's all rideable if you're happy to take your time and plod.
