Best time to go
For the quietest experience, arrive early or choose a weekday. The waterfall is a better subject on a wet or overcast day than in harsh midday sun, while softer woodland light helps show the separate drops and wet rock. Bring waterproof shoes, a layer for the shaded valley and rain protection. Mobile coverage can be limited, so download any audio trail before setting out if you want the history of the former gunpowder works along the route.
Tyddyn Gwladys is a basic trailhead with free parking and picnic tables beneath trees beside the river. Do not count on toilets or refreshments there. The larger Coed y Brenin Visitor Centre is the place to handle those needs before or after the walk. Keep clear of the water and gorge edge, especially after heavy rain, and do not climb on the wet rocks around the falls.
