This 3 acre lake is situated above the village of Llan Ffestiniog on the B4407 towards Ysbyty Ifan. Tales of Rods being broken and big fish getting away are accepted as fact. Two pound trout being no rarity, a 3 ¾lb trout was taken in 2003 on a fly.

The lake is heavily covered with lilies during the summer months but open-water is available by the roadside. Llyn Dubach Y Bont is 1,330′ above sea level and has parking at the lakeside.

As of 2024, tickets can no longer be booked online with The Fishing Passport. Information on local ticket outlets can be found on the clubs website.
