Sitting below the northern slopes of a mountain called Cnicht, lies LLyn yr Adar, in the Snowdonia National Park. Porthmadog lies to the southwest, and Betws-Y-Coed to the north east.

The llyn measures approximately 350m long by 200m wide, and can be fished in its entirety all the way around. Due to the fact that it sits in a shallow bowl, the water can be quite protected, but not enough to stop a good ripple forming on the water in a moderate wind.

The southern shore of the llyn, appears to be quite shallow, shelving away gradually, however trout can be caught all along this edge, but they generally seem rather small and in the 4-5” size.
The west bank appears to drop away into deeper water, particularly near the small cliffs towards the northwest corner, and fish in the 10-12” size are plentiful. The northern and eastern banks, fish similarly well. Llyn Adar has a good reputation, and fish of 2lb get caught each season, although none were seen on our visit.

The llyn is easily suited to cast and walk tactics with a team of 2 or 3 flies and in July, black and red hogs, black and orange hogs small muddlers, elk hair caddis etc all did well and brought in the fish.

The easiest route to get to Llyn yr Adar, is to park at the car park in Tanygrisiau, and follow the stone track up to Cwmorthin, and continue up through the quarries. Take the track past Llyn Cwm-corsiog and continue to Llyn yr Adar.

One word of caution. The tracks in places are little more than sheep tracks and in places disappear. Also low cloud can move in very quickly making navigation difficult so it would be wise to take suitable navigation equipment and know how to use it.
