Cymyran Beach, Rhosneigr, Anglesey, North Wales

Cymyran Beach is situated at the western end of Rhosneigr, separated from Crigyll Beach by a rocky outcrop (known as Ys Feiri). The stream of the Afon/River Crigyll runs onto the sand close to the Rhosneigr end.

The whole length is backed by low sand dunes and, at the far end of Cymyran Beach, you’ll notice the inland-sea, or channel, that runs between Holy Island and Anglesey. Close enough to Rhosneigr, but far enough away to get some peace and quiet, Cymyran never gets very busy, and is a perfect dog-walking spot. It’s also a haven for fishermen, and horse-riders - who enjoy the wide open space! Crigyll Beach is closer to the amenities of Rhosneigr and usually busier.


The RAF Valley base is situated directly behind Cymyran and Crigyll Beaches. Being an active air base means there are frequent training flights going on - which can be a tad noisy! However, they rarely fly at weekends - and many visitors enjoy the free spectacle, with plane-spotters often to be found in the area!

Beach info

Beach type

Sand and shingle.


There are no facilities on the beach.


  • You can park in Rhosneigr (it has both pay and display and free roadside parking available) and walk onto the beach. When you’re on the main beach, turn right for  Cymyran beaches.

  • You get to Cymyran Beach (and from here to Crigyll) from the RAF Valley road too. From the A55 Expressway, come off at Junction 4 for Bryngwran, A5, Bodedern. Keep left and follow the signs for RAF Valley. You’ll pass a lake (on the right) and go over a railway bridge. You’ll notice the RAF camp’s entrance on your left. Directly ahead is Anglesey Airport. Follow the road for about half a mile (around the perimeter of the camp to the right) until you come to a junction where you need to turn left. Follow the road past the Cymyran Hotel. Carry on for a few hundred yards until the road ends, where there’s a fence at the end of the runway. You can park here for free. Make sure you always keep the road from the Crash Gate clear though! There’s also a very rough track to the right - with parking at the end of it.



Access Cymyran ends are relatively easy - with short walks over dunes.

Dog restrictions

Dogs welcome all year round with no restrictions.

Flora & Fauna
Weather & tide

At the far end of Cymyran beach runs the channel between Holy Island and Anglesey, also known as the inland sea. Whilst a fantastic fishing spot, the currents here can be very dangerous - so be careful! Some say the conditions here are more like a river than sea-fishing.

 The tide-race formed between the two landmasses encourages shoals of fish to whip up and down on the tide-change - with the bigger species (like bass) chasing after and feeding off the smaller ones (like herring)!!

 There are lots of fishing marks along the two beaches, with bass, herring, flounder, rays, dogfish and mackerel being common catches.
