Nantcol Waterfalls (Rhaeadr Nantcol) tumbles along the Afon Cwmnantcol in the steep-sided Cwm Nantcol valley, set within Snowdonia National Park near the village of Llanbedr in Gwynedd.

The valley sits in the foothills of the Rhinogydd Mountains and is particularly dramatic after heavy rainfall, when the falls run at full force.

A signed nature trail, originally opened in 1970, follows the river for roughly 2 kilometres and takes around an hour to complete.

The route passes a lower waterfall viewable from a riverside island, then climbs a short, steep section of steps before levelling out through woodland, passing a derelict farmhouse left to nature.

Information plaques along the way explain how the terrain was shaped over the centuries. The river also offers spots for paddling and swimming.
