This has been pinned in the wrong place! The arch where this is pinned is Bwa Ddu. The picture is labelled correctly but should be located north of Porth Swtan

There are over 75 hiking trails around Trearddur, catering to various skill levels. You'll find a good mix of easy strolls, moderate coastal paths, and more challenging ascents, particularly around Holyhead Mountain.
While many coastal paths can be rugged, some sections offer easier terrain. For a relatively easy walk with dramatic scenery, consider the South Stack loop — Anglesey. It's a shorter route that provides stunning views of the cliffs and lighthouse area. For stroller access, paved sections within areas like Holyhead Breakwater Country Park might be more suitable, though specific stroller accessibility on all trails can vary due to natural terrain.
Many trails around Trearddur, including sections of the Anglesey Coastal Path, are dog-friendly. However, it's crucial to keep dogs on a lead, especially near cliff edges, livestock, and during nesting seasons to protect local wildlife, particularly seabirds at places like the South Stack Cliffs RSPB Reserve. Always clean up after your dog.
Yes, Trearddur offers several excellent circular walks. A popular choice is the Holyhead Mountain Circular Trail, which provides dramatic coastal views from Anglesey's highest point. Another option that combines coastal and mountain scenery is the South Stack & Holyhead Mountain loop from Holyhead Breakwater Country Park.
Parking is available at various points along the coast and near popular trailheads. Key parking areas include those near Trearddur Bay beach, and at Holyhead Breakwater Country Park, which serves as a starting point for many routes around South Stack and Holyhead Mountain. Always check local signage for any parking fees or restrictions.
Trearddur's trails are rich with natural beauty and landmarks. You can explore dramatic cliffs, sandy coves like Porth Diana, and unique geological formations such as the natural rock arches Bwa Gwyn and Bwa Du. Highlights include the iconic South Stack Suspension Bridge and Lighthouse, the summit of Holyhead Mountain, and the historic St Gwenfaen's Well. The Porth Dafarch Beach is also a scenic spot.
The best time to hike in Trearddur is generally from spring through autumn (April to October). Spring offers the chance to see wildflowers and nesting seabirds at South Stack, while summer provides warmer weather for coastal walks. Autumn brings beautiful light and fewer crowds. Always be prepared for changeable coastal weather, regardless of the season.
Yes, for those seeking a challenge, the Trearddur area offers routes with significant elevation gain and rugged terrain. The View of South Stack Lighthouse – View of Gogarth Bay loop from Holy Island is a longer, more difficult route that covers a substantial distance and elevation. Ascending Holyhead Mountain also presents a good challenge with rewarding views.
The area is highly rated by the komoot community, with an average score of 4.6 stars from nearly 300 reviews. Hikers frequently praise the breathtaking coastal scenery, the dramatic cliffs around South Stack, and the diverse landscapes that range from sandy beaches to heathlands. The well-maintained Anglesey Coastal Path is also a highlight for many.
Public transport options are available, though they may require some planning. Local bus services connect Trearddur Bay with Holyhead, which is a larger transport hub. From Holyhead, you can access areas like Holyhead Breakwater Country Park, a common starting point for trails around South Stack and Holyhead Mountain. For detailed bus routes and timetables, it's best to check local transport provider websites.
Trearddur Bay itself has several pubs and cafes where you can refuel before or after your hike. Along the Anglesey Coastal Path, especially in more remote sections, options may be limited, so it's advisable to carry snacks and drinks. However, villages like Rhoscolyn, which can be reached via coastal path sections, may offer additional refreshment stops.
Given the coastal and sometimes rugged terrain, essential items include sturdy hiking boots, waterproof and windproof layers, and plenty of water. Sun protection (hat, sunscreen) is also important, as coastal exposure can be high. A map or GPS device (like komoot's app) is recommended, especially for longer routes, and binoculars can enhance wildlife viewing opportunities.
