Situated in the Dyffryn Mymbyr valley amongst some of Snowdonia’s highest mountains (including Moel Siabod, whose summit view is one of the finest in the national park) is Llynnau Mymbyr. The lake is approx 3/4 mile long, and reaches depths of up to 30 feet. Its popular with both tourists and watersports enthuasiats alike – the former no doubt due to the stunning views of the Snowdon horseshoe, which on a clear and still day produces an epic reflection in the lake – a photo opportunity not to be missed!
The lake is ideal for paddle boarding, canoeing and wild swimming – with a number of access points direct from the A4086, which runs along the lakes northern edge. Being exposed to the elements and situated close to Capel Curig, refutedly the wettest place in Wales, one should enter the water only in favourable conditions.
On the eastern bank of Llynnau Mymbyr is Plas Y Brenin, an outdoor education centre whose water based activities take place on the lake. The centre facilities include a cafe bar/bistro open to the public, and an indoor bouldering/climbing wall.
Parking is via a number of lay-bys situated along the A4086, including approx midway along the lake where a delta on the northern bank has almost split the lake in two – this is perhaps the place to view that mirror reflection! There is also direct lake access (via a path) if you so happen to be staying at Garth Farm campsite.
