Why it's Wildland
8.0A reservoir tucked beneath the crags of the Crafnant Valley, where a waymarked lakeside circuit passes an 1896 monument and looks towards old slate mines and rare ash woodland.
The lake is only part of the appeal: a dramatic mountain-framed setting, a waymarked circuit and an accessible riverside trail give visitors several ways to experience the valley. The view from the head of the lake is described by Natural Resources Wales as one of North Wales’s finest.

Verified history
Llyn Crafnant is a reservoir and was once the water supply for nearby Llanrwst. Natural Resources Wales says Richard James gave the lake to Llanrwst in 1896, and a monument beside the lake commemorates the gift. A supplied Tripadvisor description additionally says the reservoir was dammed at its northern end in 1874; this detail comes from an AI-generated description on that page and should be treated with caution.
Hidden details
The monument marks a gift to Llanrwst — The lakeside monument commemorates Richard James’s 1896 gift of the lake to the town. Look for it as you walk the circuit.
Rare ash woodland on the steep cliffs — Natural Resources Wales identifies the woodland on the steep cliffs above the lake as a rare type of ash woodland, best viewed from the circuit because there are no paths through the very steep reserve.
