Rhosneigr has two large sandy beaches, both brilliant for exploring, walking or playing on. They even won the Green Coast seaside award. The Wales Coast Path and the Isle of Anglesey Coast Path both walk past here.

Found this lovely cafe off the A5 London Road. Perfect little cafe with amazing views, some funny sheds you can sit in, and plenty of outside seating. Open Sat - Wednesday 11am till 4pm closed Thursday and Friday Would definitely recommend it. The path that carries on you will also see public toilets in the carpark. If you go beyond there, it's a dead end for bikes, but ok for walkers.

Dead end for road bikes. It's a big carpark, but it does have a public toilet 🚻 Nice on a sunny day, but not really a good highlight unless you need the loo.

The Stanley embankment is known locally as The Cob, it joins Anglesey to Holy island. The cob is basically the old A5 road and rail link to Holyhead. When travelling on the newer A55 to Holyhead it can be seen to the right as you cross the inland sea. The Cob creates a pinch point where the vast tidal forces push the water through at high tide. At low tide it a vast expanse almost devoid of water.

The bridge itself takes the same name as the village it is situated in and is one of three bridges connecting Holy Island and Anglesey. The bridge is approximately four miles (6.5 km) from Holyhead via the old road route, giving it, and the village, its name. A bridge at this location was in existence by 1530, and was the only land route to Holyhead until the construction of the Stanley Embankment in 1823. It is 120 metres (390 ft) long and carries the B4545 road over the Cymyran strait. I think the crossing over the water is about 5km

Frequently Asked Questions

Is there a continuous circular walk directly around Llyn Llywenan?

There isn't a single, waymarked footpath that circumnavigates the entire lake. Instead, the area is crisscrossed by a network of public footpaths and quiet country lanes that allow you to explore the tranquil countryside and get close to the lake's shores in various sections.

Are the walking trails around Llyn Llywenan suitable for dogs?

Yes, dogs are generally welcome on the public footpaths around Llyn Llywenan. However, the routes often pass through farmland with livestock. It's essential to keep your dog on a lead and under control, especially near sheep. Also, be mindful of the area's status as a Site of Special Scientific Interest and its importance for ground-nesting birds.

What is a good easy hike for families or beginners?

For a gentle walk suitable for all fitness levels, the Llyn Maelog loop from Rhosneigr is an excellent choice. It's a relatively flat 4.5-mile (7.2 km) route that takes under two hours and offers a lovely introduction to the region's lakeside scenery without being too strenuous.

Where can I park to start a walk near Llyn Llywenan?

Parking is generally limited to informal lay-bys and on-street parking in nearby villages like Bodedern or Bryngwran. There are no large, dedicated car parks directly at the lake. When choosing a route, check the starting point for specific parking suggestions. Always park considerately and do not block gateways or narrow lanes.

Can I reach Llyn Llywenan using public transport?

Reaching the immediate vicinity of Llyn Llywenan by public transport is challenging due to its rural location. Bus services are limited and may not get you directly to a trailhead. The nearest train station is in Valley, a few miles away. It's generally more practical to access the area by car.

What are some interesting things to see on a walk in the area?

Besides the lake itself, a walk can take you to historical sites. Near the lake's southern end, you can find the Presaddfed Burial Chambers, a pair of Neolithic tombs. On the northwestern shore stands the historic Ainon Chapel, a charming 19th-century Baptist chapel built from massive field stones.

Is the area good for birdwatching?

Absolutely. Llyn Llywenan is a Site of Special Scientific Interest and a haven for birdlife. It's particularly noted for its wintering wildfowl, including species like teal, wigeon, and shoveler. You may also spot a black-headed gull colony, making it a rewarding destination for birdwatchers year-round.

How does hiking around Llyn Llywenan compare to Snowdonia?

Hiking here offers a completely different experience. Llyn Llywenan provides gentle, rolling countryside and peaceful lakeside paths, focusing on tranquil scenery and wildlife. In contrast, Snowdonia is characterized by rugged mountains, dramatic ridges, and strenuous ascents. If you're looking for a relaxing walk rather than a challenging mountain climb, Llyn Llywenan is an ideal choice.

Are there any pubs or cafes for after a hike?

The immediate lake area is very rural with no pubs or cafes on its shores. You will need to travel to nearby villages like Bodedern, Gwalchmai, or the coastal town of Rhosneigr to find pubs, cafes, and restaurants for refreshments after your walk.

What do other hikers think of the trails around Llyn Llywenan?

The routes in this region are highly regarded by the komoot community. Hikers often praise the peaceful, rural atmosphere and the beautiful scenery around the largest natural lake on Anglesey. With over 1,200 hikers having explored the area, it's a well-loved spot for those seeking tranquility.

Are there any longer, more challenging hikes available?

Yes, for those seeking a longer walk, the Trefignath Burial Chamber – Trearddur Bay Beach loop from Valley is a great option. This moderate 8.4-mile (13.4 km) route takes you through varied landscapes and requires a decent level of fitness.

What kind of footwear is recommended for the trails?

Sturdy, waterproof walking shoes or boots are highly recommended. The paths can be uneven and, given the wetland nature of the area, are often muddy, especially after rain. Good footwear will ensure you are comfortable and sure-footed throughout your hike.
