Great place to learn to dive if the sea is rough. Although it is deep, it goes down in steps so the depth can be pitched for the experience of any diver. Over dirt track onto site.

10Puffin Island
The island can be dived on any side but the tip nearest the mainland is a good place to finish on your safety stop as the resident seals may come and play with you. ( they only nibble your fins). can be dived as a drift dive but watch out for the pleasure boats who come past regularly in the summer. A smb and good boat cover are a must Puffin Island is also known as Llangoed.

12Trefor Pier
Lots of life around the legs of the pier. Easy access from the shore. If you don;t mind a surface swim and the water is choppy the best access if via the harbour steps. Also beware of fishing lines even though officially closed the life under the pier still attracts a lot of attention at weekends. Park directly at the start of the pier.

14Menai Straits
A rollercoaster! If doing by boat, go up past the swillies then drop in for the ride of your life. Best to keep the dive boat close to your marker bouy, as most weekend boaters haven't a clue what it means! Either by boat or down the slipway under Menai bridge.

15Blue lake
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.
