Llyn Geirionydd

Llyn Geirionydd lies in a valley where the northern edge of the Gwydyr Forest meets the lower slopes of the Carneddau Mountains. The lake is almost a mile long and covers an area of 45 acres (180,000 m²), but is never any deeper than 50 ft (15 m) according to Jehu’s survey. The lake can be reached by car from Trefriw or Llanrwst in the Conwy valley, the lane passing through the hamlet of Llanrhychwyn, or from the road through the Gwydir Forest. Access is not particularly easy by either route, but this has not stopped the lake being the only one designated in Snowdonia to permit power boats and water skiing. Many visitors also walk to the lake from the village of Trefriw (it is on one of the Trefriw Trail routes) or from the neighbouring lake of Llyn Crafnant, which runs parallel to it, but a mile distant, the two being separated by Mynydd Deulyn, “mountain of the two lakes”.

The lake has a car park (with toilets) and the location is very popular in the summer. This car park site was once a waste tip site for the Pandora mine above, and indeed the planting of conifers in the area of the lake has considerably softened the effects of mining. There are few, if any, fish in the
