RSPB South Stack for lots of sea birds, including puffins (if you know where to look….), ravens, chough etc. It gets busy, but if you get there early enough (i.e. not too long after the cafe opens!) you should be fine. There’s a chance of seeing seals, sometimes porpoises and dolphins too. I visit often, so let me know if you want to know exactly where the puffins are and I’ll try to explain 😊 It’s nice in the evenings too, after the crowds have gone home.
Cemlyn lagoon for terns, terns and more terns. This time of the year, the noise is deafening, but it’s fun seeing them dive and fly over your head with their latest catch. There’s some lovely walks around there too and it’s a good place to see birds of prey, if you’re lucky.
Point Lynas is great for all sorts of things. I’ve never been there and not seen dolphins, but there’s lots of other interesting things there too. It’s my favourite spot to see Black Guillemots, but I appreciate that may be a bit niche!
Oh and Penrhos Coastal Park is the easiest place on Anglesey to spot red squirrels. Just ask any of the dog walkers and they’ll point you in the right direction. The feeders aren’t too far from the car park, so you can easily combine it with a trip to RSPB South Stack.
Newborough beach is absolutely stunning, but it’s not always that easy to see the wildlife, especially if there’s a lot of people. It’s still a must see for the scenery, but this time of the year it may be easier to spot wildlife in any of the places above.
