Penrhos Beach or Towyn Bay (as shown on nautical charts) is just to the east of Holyhead. It is mostly sand backed by a grassed area, with the coastal path and the A5 to Holyhead just behind. To the eastern side, low cliffs provide sheltered coves. Swimming is generally safe, but waves are to be expected from ferry movements at Holyhead port. There are free car parks (6' 6" height restriction) at both ends and Holyhead rail station is just under a mile away. It's popular with locals for swimming, dog-walking or just sitting on the benches behind the beach.
