Although fairly flat and sandy, just north of the slipway are plenty of rocks usually full of crustatians. Use slipway at and of promanade.

Although touted as "Bottomless" it has a maximum of 12m. The blueness is due to the slate that is sliding down from the far side. Entry can be either giant stride from the cliff edge or a gentle slope from the far right of footpath. Not easy! By road you have o come in from Llwyngril across the top road then drop down to the lake from here. Defenatly 4 wheel drive territory. Otherwise it is a long walk up a steep path opposite Salt's garage in Fairbourne. Entry is then through tunnels following the old quarry rail track.
