Llyn Dulyn

You'll find Llyn Dulyn tucked into the Conwy valley, a proper mountain lake that demands a bit of effort to reach but rewards you for it. The walk from Llanfairfechan takes you through forested paths that open out to this slate-grey water surrounded by steep hillsides - it's genuinely dramatic, the kind of spot where you understand why people were writing poetry about Welsh lakes centuries ago.

The lake itself is small enough that you won't spend hours wandering the shoreline, but that's not really the point. What draws people here is the walk itself and the sense of being somewhere genuine and unspoilt. It's less about the destination and more about the journey through proper mountain country. Walkers will get the most from it - families with young children might find the trek a bit much depending on fitness levels, though it's not technically difficult, just steady.

Allow two to three hours for the round trip if you're taking it at a leisurely pace and want to sit by the water for a bit. There's no café or facilities at the lake itself, so bring supplies. Being free and wild means there are no opening hours to worry about - you can go whenever daylight allows.

For a week based at one of the nearby parks like Three Streams Glamping or Ogwen Bank, this works well as a half-day excursion alongside other Conwy valley walks. It's close enough to Llanfairfechan to fit into a larger itinerary without feeling like a detour.
