Things to do near Rhosneigr
Whether you're here for a week or a weekend, there's no shortage of things to keep you busy. From world-class seabird watching to lazy afternoons on the golf course, here's our guide to the best activities in and around Trearddur Bay.
South Stack Lighthouse
One of Anglesey's most iconic landmarks, South Stack lighthouse sits on a tiny island off the western tip of Holy Island, about a ten-minute drive from Trearddur Bay. The lighthouse was built in 1809 to warn ships navigating the treacherous waters towards Holyhead port. To reach it you descend 400 steps down the cliff face — dramatic in any weather.
The lighthouse is open to visitors at certain times through the year, and the views from the island across to Ireland and the Wicklow Mountains are spectacular. Even if the lighthouse itself is closed, the clifftop walk and RSPB visitor centre at Ellin's Tower make the trip worthwhile. Free parking on site.
RSPB South Stack — seabird watching
The cliffs around South Stack are home to thousands of breeding seabirds between April and July. Puffins, razorbills, guillemots and choughs nest on the sheer rock faces, and you can watch them from Ellin's Tower, the old lighthouse keeper's lookout now run as an RSPB visitor centre.
The puffins are the main draw — arrive in late April and stay through June. Binoculars help but aren't essential; the birds are surprisingly close. Outside breeding season the cliffs are quieter but still worth visiting for the raw coastal scenery. It's one of those places that reminds you why this corner of Wales is special.
Holyhead Mountain
At 220 metres, Holyhead Mountain is the highest point on Anglesey and one of the most rewarding short walks in North Wales. The summit takes about 45 minutes from the Breakwater Country Park car park, or you can start from the South Stack car park for a slightly shorter route. The path is rough in places but well-trodden.
At the top you get 360-degree views — Ireland to the west, Snowdonia to the south-east, the Wicklow Mountains if the air is clear, and the full sweep of Anglesey laid out below. The summit also has the remains of a prehistoric hill fort (Caer y Tŵr), a Scheduled Ancient Monument, with Roman-era fortifications layered on top. History and views in one walk.
Breakwater Country Park
On the northern edge of Holyhead, this 200-acre country park is built around the massive Victorian breakwater that protects Holyhead harbour. It's a flat, easy walk along the breakwater itself — perfect for families, dogs, and anyone who wants fresh air without a serious hike.
The park also serves as the starting point for walks up Holyhead Mountain and along the coast towards South Stack. There's a car park, toilets, and a visitor information point. On a clear day you can watch the Irish ferries coming and going from the port while the kids run around on the grass. One of those places that doesn't look like much on paper but works perfectly in practice.
Kayaking and paddleboarding
Trearddur Bay's sheltered waters make it one of the best spots on Anglesey for getting on the water. Blu Chameleon, based right on the bay, hire out kayaks and paddleboards by the hour — no experience needed, and they'll kit you out with a wetsuit and buoyancy aid. On a calm morning the water is almost turquoise, and you can paddle along the coast to discover small coves and rocky inlets that you'd never find on foot. Keep your eyes open for seals — they're regular visitors to the bay.
For something more adventurous, several local companies offer coasteering sessions along the rocky coastline south of Trearddur Bay, combining cliff jumping, rock scrambling, and swimming through sea caves. See our directory listing for Blu Chameleon.
Coasteering
If kayaking is too gentle, coasteering is the answer. Part rock climbing, part cliff jumping, part wild swimming — you work your way along the base of the cliffs in a wetsuit, scrambling over rocks, jumping off ledges into deep water, and swimming through gaps in the rocks.
Several operators run sessions from around Trearddur Bay and Rhoscolyn, including Anglesey Adventures and Anglesey Outdoors, both based on Porthdafarch Road. Sessions typically last two to three hours and all equipment is provided. It's exhilarating, safe with the right guides, and gives you a completely different perspective on the coastline. Suitable from around age 8 upwards.
Holyhead Golf Club
A proper 18-hole clifftop links course with views that distract you from your game. Holyhead Golf Club sits on the headland between Trearddur Bay and South Stack, and several holes play right along the cliff edge with the Irish Sea below.
It's a challenging course in the wind — and it's almost always windy up here — but the setting is spectacular. Green fees are reasonable and visitors are welcome. The clubhouse has a bar and serves food. If you're a golfer staying in Trearddur Bay, this is a must-play.
The Beach Golf Course and Foot Golf
For something more casual, The Beach Golf Course on Lon St Ffraid in Trearddur Bay offers a relaxed 9-hole par-3 course that's perfect for families and beginners. They also run foot golf — basically golf but with a football, which kids love.
It's right in the heart of the village, no booking needed, and you can fit a round in during an hour or so. A nice option for an afternoon when you don't want to commit to a full day out. BluFin fishing and outdoors shop is also based here if you want to pick up some gear.
Trearddur Bay Lifeboat Station
The RNLI lifeboat station at the north end of the bay has been part of the village since 1967. It's worth a visit — you can see the lifeboat and learn about the volunteer crew who head out in all conditions to keep the waters safe.
They hold open days through the year where you can meet the crew and see the boat up close. There's a small shop selling RNLI merchandise. It's one of those community places that reminds you this isn't just a tourist village — people live and work here, and the lifeboat crew are a big part of what makes it tick.
Anglesey Sea Zoo
About 25 minutes' drive from Trearddur Bay on the other side of Anglesey, the Sea Zoo is Wales' largest marine aquarium. It's focused entirely on species found around the Welsh coast — no tropical fish, just the incredible marine life that lives in the waters you've been swimming in.
Highlights include the lobster hatchery, seahorse nursery, and live diving displays. Outside there's crazy golf, a bouncy castle, and a playground. It's a solid rainy-day option for families, or a good half-day trip combined with a stop at the nearby Llanfairpwllgwyngyll (yes, that one) for a photo with the station sign.
