Llanddwyn Island: The North Wales beach with a mountain backdrop
If you’re someone who can’t decide between the beach and mountains, Llanddwyn Island (Ynys Llanddwyn) is the perfect destination. Nestled on the edge of Anglesey’s coastline, this unique spot offer a sandy beach, panoramic views of Snowdonia, woodland trails, and two historic lighthouses. We visited in January and it’s a fantastic year-round destination for families, adventurers, and anyone looking for a scenic day out.

Getting there
Llanddwyn Island is located on the southwestern tip of Anglesey, just off Newborough Beach (Traeth Llanddwyn). To reach it, head to the Newborough Forest car park, which is managed by Natural Resources Wales. The parking area operates on a barrier system, with a daily charge of around £7 (cash or card accepted). Toilets are available at the car park, but there are no facilities on the island itself, so plan accordingly.
The car park opens early and closes at dusk, and overnight camping is not permitted in the car park or on the island. However, nearby campsites and accommodations make it easy to extend your stay in the area. From the car park, you can walk along Newborough Beach to get there or through the forest which runs alongside the beach.

Dogs
If you’re visiting with your dog, it’s worth noting that dogs are restricted on parts of Newborough Beach and Llanddwyn Island during the peak season (April to September). During this time, dogs are only allowed on designated sections of the beach, clearly marked by signage. Outside of these months, the restrictions are lifted, and dogs can explore freely, making it a better time for pet-friendly visits.

Wild swimming
Llanddwyn Island is a stunning spot for wild swimming, thanks to its clear waters and mountain backdrop. The main beach offers ample space to swim, with gradual sandy entry and exit. For those seeking more seclusion, small bays around the island provide quieter swimming spots, often sheltered by rocky outcrops.
It’s essential to check tide times before heading out, as the island becomes cut off from the mainland at high tide. Water temperatures can be brisk, especially outside of summer, so a wetsuit is a good idea if you’re not used to cooler waters. Always swim with caution, as there are no lifeguards in the area, and conditions can vary.

Walking
Llanddwyn Island and its surroundings are a walker’s paradise. The main route from the car park takes you through Newborough Forest, which is filled with pine trees and wildlife. From here, you’ll emerge onto the expansive Newborough Beach, with views of the mountains in the distance.
To reach Llanddwyn Island itself, you’ll walk along the sandy shore before crossing a narrow strip of land. Keep an eye on tide times, as high tide can make the island inaccessible. Once on the island, you’ll find a network of paths that lead to its key features, including the historic Tŵr Mawr and Tŵr Bach lighthouses, as well as breathtaking viewpoints overlooking the mountains and coastline and wild ponies.
For a longer walk, explore the forest trails that wind through Newborough Forest or follow the beach northwards for even more coastal beauty. Whether you prefer a short stroll or a more extended hike, Llanddwyn Island offers something for every kind of walker.
The walks are easy to navigate and good under foot making it easy for little ones to have a good leg stretch too.

The lighthouses
Llanddwyn Island is home to two historic lighthouses, Tŵr Mawr and Tŵr Bach, both of which are key features of the island.
Tŵr Mawr, the larger of the two, is a whitewashed tower with a traditional design that resembles a windmill. It was built in the 19th century and served as a guiding light for ships navigating the Menai Strait. Its elevated position offers stunning views of the surrounding coastline and mountains.
Tŵr Bach, the smaller lighthouse, predates Tŵr Mawr and is located nearby. Though simpler in design, it adds to the charm of the island and is a favorite spot for photographers.
Both lighthouses are easily accessible via walking paths on the island and make for great stopping points as you explore. They are surrounded by rugged cliffs and sweeping sea views, making them perfect for soaking in the scenery or snapping a few memorable photos especially at sunset.
