Holyhead to Trearddur Bay

Both ends of this route lie within the Anglesey Area of Outstanding Natural Beauty — and it’s easy to see why. Begin in Holyhead, a historic port town on the Irish Sea, and follow the coastal path south toward Trearddur Bay — a charming seaside village nestled on the southern tip of Holy Island. History lovers will appreciate the ancient landmarks scattered along the way, including the prehistoric settlement of Penrhos Feilw. The island earned its “Holy” name from the abundance of burial chambers, standing stones, and early religious sites.

Newborough and Ynys Llanddwyn Circuit

Energetic dogs (and their humans!) will love this expansive 10-mile loop. With up to four hours of walking time, it’s ideal for those seeking both exercise and breathtaking scenery. Though lengthy, the terrain is gentle and varied — think dunes, woodland paths, and sweeping coastal vistas. Don’t miss the iconic Llanddwyn Island, home to romantic ruins and panoramic views across Cardigan Bay.

  • Estimated time: 4 hours
  • Distance: 10 miles
  • Nearby parking: Car Park, Niwbwrch, Llanfairpwllgwyngyll

Beaumaris Circuit

History meets accessibility on this delightful year-round walk around Beaumaris. Though just 1.3 miles long, it delivers big rewards: sweeping views of Snowdonia and the majestic, moated Beaumaris Castle — begun in 1295 as part of Edward I’s campaign against Welsh resistance. Though never fully completed, its imposing walls and towers remain remarkably intact. For extra historical depth, visit nearby Beaumaris Gaol, complete with Victorian punishment cells and an original treadwheel.

Prefer a longer stroll? Head to Beaumaris Beach — but note that dogs are restricted during peak season, so plan accordingly.

  • Estimated time: 30 minutes
  • Distance: 1.3 miles
  • Nearby parking: Beaumaris Green Car Park

Porth llechog to Industrial Ruins

This 4.5-mile circular walk blends coastal drama with quiet countryside charm. Start in Bull Bay (parking available), then follow the Anglesey Coastal Path down to a fascinating abandoned industrial site — remnants of Anglesey’s slate and copper mining past. While the rusting structures add a touch of eerie intrigue, the real stars are the sea views and rolling green hills surrounding you.

  • Estimated time: 2 hours
  • Distance: 4.5 miles
  • Nearby parking: Maes Parcio Ffordd Porth Llechog

Red Wharf Bay

Looking for a shorter, high-energy outing? Red Wharf Bay delivers. Its flat, open shoreline makes it one of the most accessible dog walks on the island — perfect for off-lead runs, beach games, or even jogging alongside your pup. As part of the Anglesey Area of Outstanding Natural Beauty, it’s also a photographer’s dream: soft sands, tidal pools, and dramatic skies await.

  • Estimated time: 30 minutes
  • Distance: 1.5 miles
  • Nearby parking: Seafront Car Park

Aberffraw

One of Anglesey’s most picturesque beaches, Aberffraw offers wide, sandy stretches backed by dunes and framed by mountain views across the Menai Strait — especially striking when Snowdonia’s peaks shimmer in the distance. Let your dog sprint freely across the soft sand while you soak in the serenity of this unspoiled stretch of coast.

  • Estimated time: 1 hour
  • Distance: 2.3 miles
