A great place to take in a view of east Eryri and the Carneddau range with easy access. See Tal y Fan in the foreground and beyond it Drum and Carnedd Y Ddelw and on even clearer days Carnedd Gwenllian

A very fine mountain that is the high point of the Carneddau range. These mountains are high, remote and so much quieter than the Glyderau or Snowdon. Fabulous walking country.

Carnedd Llewelyn is high and relatively remote, so walks there are quite a serious undertaking.

As the previous person said, it is very very wet on the outward path from the bothy. If you do decide to go anyways, make sure to have a walking stick or similar to stabilise you and determine the depth of the water before sticking your foot in it.

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.
