Llyn Gwngu

The walk down to Llyn Gwngu rewards you with one of those rare Welsh lake views that actually feels remote, even though you're only a short drive from Llanidloes. The water sits in a proper valley, dark and still most days, ringed by steep banks where sheep graze right down to the shoreline. It's the kind of place where you genuinely might not see another soul if you arrive early.

Expect a straightforward walk - nothing technical, but the path down is reasonably steep and can be boggy depending on recent weather. Allow 45 minutes to an hour if you're just going down, having a sit, and coming back up. The lake itself isn't massive, so it's not a day-long destination, but as a morning excursion or a break from a longer Powys walk, it works brilliantly.

Historically minded visitors will get more from researching the area first - there's not much signage on-site, so knowing what you're looking at beforehand helps. Families with young kids should time it for when the ground's dry; muddy banks and sheep underfoot can test patience.

If you're staying at Glangwy Farm Camping nearby, this sits nicely into a hiking loop around the area. The real pull here is the quiet. No tea shops, no facilities, no crowds. If that appeals to you, it's genuinely worth the detour. If you need bells and whistles, you'll be disappointed.
