The wonderfully serene Llyn Geirionydd is tucked away in a very beautiful part of Snowdonia. It sits in quiet seclusion among the hills above Llanrwst and Betws y Coed on the northern edge of the Gwydyr Forest. During the summer months it becomes a popular site for watersports including canoeing and windsurfing. Power boats and waterskiing (but not jet skis) are also permitted here.
The launch point is a slipway on a small slate beach. There is a car park and toilets located at the southern end of the lake (although the toilets are only open during the summer months). There is a charge for launching; payment is made via an honesty box in the car park.
The lake is 1.5km long and reaches depths of 15m. There are few fish known to exist in the lake – a possible explanation being that the waters were poisoned by contamination from the old metal mines on the hillside above the lake. Much of the visual impact of the mine workings are now shielded by the conifer plantation, but it is worth noting that the car park sits on the site of the waste tip from the Pandora mine.
There is a car park at the southern end of the lake, although the roads leading up from Llanrwst and Betws y Coed are quite convoluted and narrow.
