Dolgoch Lower Falls is the most accessible of the three waterfalls that make up Dolgoch Falls on the Nant Dol-gôch stream in Eryri (Snowdonia) National Park, Wales.

Situated within the wooded Dolgoch Ravine near Tywyn, it can be reached in roughly a ten-minute walk from the car park or via a trip on the Talyllyn Railway to Dolgoch station.

Unlike the middle and upper falls, the lower falls are accessible to wheelchairs and pushchairs, making this the easiest tier to visit. The falls are impressive year-round but are at their most dramatic after heavy rain, when water thunders through the ravine.

Voluntary donation boxes are present in the area.
