Set among truly spectacular scenery, Llyn Trawsfynydd (Trawsfynydd Lake) lies alongside the A470 trunk road between Dolgellau and Porthmadog.
Llyn Trawsfynydd is a popular spot for fishing in Snowdonia, but at five miles long and with a surface area of 1200 acres, there's never any need to worry about overcrowding; you'll have all the peace and quiet you could wish for.
The lake has a healthy head of wild brown trout and is regularly stocked with rainbow trout. You'll also find a good number of coarse fish, including perch, rudd and pike. And if you enjoy a spot of twitching, you'll have plenty of water fowl to keep you entertained, and even the occasional osprey visit if you're lucky.
