Forest lake that allows everything

This is a quick reference, not a full walked guide. The facts below — location, parking, grid reference and access — are maintained from our dataset, but we haven't published our own first-hand write-up of Llyn Geirionydd yet. Know it well? Help us get it right.

A forest-rimmed lake in the Gwydir hills above Betws-y-Coed, and one of the few lakes in Eryri where powered craft are allowed — which makes it a relaxed, unfussy spot for paddleboarding and swimming. Launch easily from the car park at the north end. For a two-lake day, walk over the low hill to the quieter, prettier Llyn Crafnant next door. Parking is paid; paddling is free.
