Llyn Conglog
water managed by Cambrian Angling Association
A short distance from the summit of Allt Fawr lies Llyn Conglog. At 2000 feet, this remote eight-acre lake is worth a visit for the views alone.
During the winter of 1947, a severe frost was thought to have killed its trout population. During the 1990s, a fry restocking program helped establish a healthy brown trout population. Today, the lake is an excellent brown trout fishery with fish of 1lb caught regularly, and 4lb fish landed every season.
At this altitude, the lake takes time to warm up and will fish better between July and September. On those balmy summer evenings, you could witness some frantic sedge fishing. Large sedges inhabit this water, so remember the dries. The east bank is the most accessible and features a marginal shelf that is crying out for a team of wet flies. Most of the west bank is high, but there are areas you can climb down to the water's edge. Cast your flies tight into the high bank where the fish lie, waiting to gobble up clumsy terrestrials or your Coch-y-Bonddu.
It'll take you about two hours to walk up to Llyn Conglog. Park at the car park at Tanygrisiau and follow the path through the old slate mine. It can be eerie walking through the abandoned buildings on a grey afternoon. You can walk up the trail leaving this industrial past behind you, across the dam at Llyn Cwm Corsiog and in a north-easterly direction towards Conglog.
Remember to take an OS map, warm clothing and waterproofs. The weather can change quickly and will be very different to the clement weather you may or may not experience at the car park.
