The Llynnau Cwm Silyn are located in the hills south of llyn Nantlle. A remote pair of lakes in the heart of Snowdonia, they contain wild brown trout and are very lightly fished due to the distance from the road, an easy walk of just over a mile on a well defined track. Anglers are advised to equip themselves adequately and always inform someone of your destination. Nearest village Llanllyfni LL54 6SL Both lakes have crystal clear water and are rocky with some weed beds adding character. The upper llyn under the crag is challenging, it is quite shallow for most of the fishable margin, with deeper water just out of reach. Fish here appear to be very small and not numerous. The lower lake has more abundant wild trout averaging 9 to 11 inches. It is deeper closer in with better access, although the banks are rough in places. Puchasing a ticket for this llyn also allows you to fish Llyn Cwellyn and Llyn Padarn on the same day.
