Nice cycle path alongside the lake and away from traffic.

For the circular route around Allt-lwyd there are some boulder like sections very difficult on a gravel bike on the north side climb. I’d recommend using the other south side of the hill for the climb (tarmac to top) and at least the worst sections can be done downhill. You’ll still have one tricky uphill bit though. Can get wet w/ deep puddles after extended rain.

A lovely gated lane and track to the northern shore of Llyn Mwyngil offers a tranquil, traffic-free ride running opposite the busier B4405 main road. There are a few gates to navigate as you pass along here next to the old farmstead, but its well worthwhile for these lovely views across the water.

The Bearded Lake or Llyn Barfog is a pretty mountain lake below Mynydd y Llyn. It's fringed with water lilies and other plants which may explain its name. Legend has it that once a monster lived here, terrorising the local people. King Arthur came to rid the area of the menace, lassoing the monster with magical chains and dragging it out of the lake with his horse Llamrai. You can even see the horse’s footprint in a nearby rockface - Carn March Arthur.

The key point to know about this NCR is that as you complete the climb the road falls apart and it goes from gravel to rocks near the top. Several gates to open, too. I would not recommend this to anyone with tyres less than 700x40c.... however, the views are breath-taking, the climbs are huge fun and the stop at Cregennan lake is EPIC!!!

A short walk over the golf course and you are on track for the lake, a lively peaceful place, where you can watch the geese flying in and out, great for a lunch break.

Worth the gentle stroll up the many trails to get here, sitting lakeside with a flask and some food watching the ripples over the water as the geese fly in and out. Peaceful place.
