The Devil's Appendix (Welsh : Nant Clogwyn y Geifr) [1] is the tallest single-drop waterfall in Wales and one of the tallest in the United Kingdom. It is a plunge style waterfall located on the Clogwyn y Geifr cliffs beside Twll Du in Cwm Idwal, Snowdonia, Wales.
It is formed where a small stream falls for approximately 305 feet (93 metres) to reach the slopes above Llyn Idwal. [2] Depending on flow and the ambient temperature, it can be either an ice climbing route, a single drop waterfall, or a broken waterfall. [3]
