Pistyll y Llyn Waterfall

The walk to Pistyll y Llyn takes you through proper woodland, following a stream that gets louder as you climb. Once you reach the waterfall itself, you've got a decent cascade dropping into a pool - nothing that'll take your breath away like Snowdonia's bigger falls, but it's genuine and feels remote enough that you won't be jostling for photos.

It's the kind of place that works well for walkers who want a straightforward goal without needing full-day kit. Families with kids who can manage muddy paths and a bit of scrambling will get something out of it, though younger children might find the payoff underwhelming if the stream's running low. Count on an hour or so for the whole excursion depending on your pace and how long you linger by the pool.

Machynlleth's nearby if you need supplies before heading out. If you're based at Gwerniago Campsite - a solid option about 4.5 miles away - this waterfall makes a decent morning walk before lunch back at the van. Worth the detour if you're in the area exploring Powys proper, but don't rearrange your whole trip around it. The real charm comes from how quiet it is rather than the spectacle of the water itself.
