Llyn Melynllyn, reservoir in Conwy County Borough, Wales, UK
Llyn Melynllyn is a small mountain lake in the Carneddau range of North Wales, situated at over 2,000 feet elevation. Steep rocky cliffs surround it on the western side, while streams from the slopes flow down to feed the water below.
A dam was built at the northern end of the lake in 1887 to supply water to the nearby town of Llandudno. The structure was deliberately destroyed in 1970 to stop the lake from being used as a water source.
The name Llyn Melynllyn comes from Welsh and means 'yellow lake,' possibly referring to the water's color under certain light. The area reflects Welsh heritage, where this remote mountain landscape has long been part of local life and tradition.
There is no road to the lake, so reaching it requires walking or hiking along natural trails. Bring sturdy footwear, water, and snacks, as there are no shops or facilities on site.
The lake is home to wild brown trout and Arctic char, with the trout ranging from about 8 ounces to 2 pounds. Anglers can purchase fishing permits through the Fishing Passport online service to fish in this remote mountain water.
