The Aberdulais waterfall is a small waterfall in the town of Aberdulais in south Wales (United Kingdom).
In the town center of Aberdulais the river Dulais plunges down over sandstone rocks before it ends in the river Neath. The Aberdulais waterfall is only 4 meter high but is nice to see.
At the waterfall there is a big power wheel generating electricity. Since 1584 the wheel is in use and power has been drawn for manufacturing copper.
