The ferry from Dublin has just passed, leaving a white wake across the Irish Sea as you stand on the cliffs above South Stack. Below, guillemots crowd the ledges and the lighthouse keeps its patient watch. This is Anglesey at its most elemental — salt wind, seabird calls, and the kind of vast coastal views that make you forget you’re only a few hours from Manchester.
A weekend isn’t enough to see everything on the Isle of Anglesey (Ynys Môn), but it’s enough to understand why people keep coming back. This itinerary balances adventure with atmosphere, covering the island’s wild western coast, its most romantic landmark, and the kind of evening where you’ll end up staying for one more song at a harbourside pub.
Saturday
Morning: Coasteering at Rhoscolyn
Start the weekend properly — in a wetsuit, jumping off rocks into the Irish Sea.
Coasteering combines swimming, cliff scrambling, and controlled jumping along Anglesey’s coastline. Several operators run sessions from Rhoscolyn on Holy Island, where the geology cooperates perfectly: sea caves to swim through, natural platforms at various heights, and water clear enough to see the bottom when you’re mid-air above it.
No experience is necessary. Guides assess conditions and choose routes to match your group’s confidence — first-timers might work up to a five-metre jump, while repeat visitors can push higher. Wetsuits, helmets, and buoyancy aids are provided. You just need to arrive willing to get properly cold and properly exhilarated.
Sessions typically run two to three hours. Book the morning slot and you’ll have worked up a serious appetite by lunchtime.
Afternoon: Newborough and Llanddwyn Island
After drying off and refuelling, head to Newborough Forest and its hidden treasure: Llanddwyn Island.
The drive from Rhoscolyn takes about 35 minutes, crossing back onto the main island and down through farmland to the forest car park. From there, a path winds through Corsican pines before opening onto Newborough Beach — a long sweep of sand facing the Menai Strait and the mountains of Snowdonia beyond.
Llanddwyn Island sits at the beach’s far end, connected to the mainland except at the highest tides. The walk out takes roughly 25 minutes at an easy pace, crossing tidal flats where oystercatchers probe for shellfish.
The island itself is small enough to explore in an hour but atmospheric enough to hold you longer. Ruined church walls mark the site of St Dwynwen’s sixth-century hermitage — she’s the Welsh patron saint of lovers, and the island draws couples year-round. Two disused lighthouse cottages, a Celtic cross, and rock pools on the western shore complete the scene. On a clear afternoon, the Llŷn Peninsula stretches across Caernarfon Bay to the south and the peaks of Eryri (Snowdonia) rise directly east.
Time your return walk to leave the beach before dusk, especially if you want to catch the evening light on the forest path back.
Evening: Rhosneigr
Finish Saturday in Rhosneigr, a low-key surf village on Anglesey’s west coast about 15 minutes’ drive from Newborough.
The village has a handful of good places to eat — nothing formal, mostly the kind of spot where sandy feet won’t raise eyebrows. After dinner, check whether the Oyster Catcher is hosting live music. The pub sits right on the waterfront and draws local musicians for acoustic sets that can run late when the crowd’s right. It’s the sort of evening where you plan to stay for one drink and leave three hours later.
Sunday
Morning: South Stack Cliffs
Start Sunday with big views at South Stack, on the northwestern tip of Holy Island.
The RSPB reserve here protects one of Wales’s most important seabird colonies. From spring through summer, the cliffs host thousands of guillemots, razorbills, and puffins. A path from the car park leads to Ellin’s Tower, a castellated building converted into a wildlife viewing station with telescopes trained on the nesting ledges.
If you want to visit the lighthouse itself, be aware it involves descending (and re-ascending) around 400 steps cut into the cliff. The lighthouse opens seasonally; check current times before planning around it.
The clifftop walking here connects to the Isle of Anglesey Coastal Path, which circles the entire island over 125 miles. You don’t need to commit to the whole thing — even a mile or two along the headland gives you the full coastal-path experience: gorse, heather, sea pinks, and the Irish Sea stretching to the horizon.
Afternoon: Beaumaris
Cross back to Anglesey’s eastern side for a final afternoon in Beaumaris, facing the Menai Strait.
Edward I’s castle here is the most technically perfect of his Welsh fortresses — it was never finished, but what exists is a masterpiece of concentric military design. You can walk the walls and imagine the engineering that went into a building designed to be unbreachable (and, eventually, never attacked).
Beyond the castle, Beaumaris is simply pleasant. A Georgian high street with independent shops. A Victorian pier. Ice cream eaten watching yachts in the strait. It’s a gentler note to end on after the wilder energy of the west coast.
Practical tips
Getting there: Anglesey is connected to mainland Wales by two bridges — the Menai Suspension Bridge and the Britannia Bridge. From Chester, the drive takes roughly 90 minutes; from Liverpool or Manchester, allow two hours or slightly more.
Where to stay: Base yourself on Anglesey rather than the mainland — the west coast (Rhosneigr, Trearddur Bay) puts you closer to Saturday’s activities, while the east (Beaumaris, Menai Bridge) offers easier access to Sunday’s stops. Either works for a weekend this compact.
Tides matter: Check tide times for Llanddwyn Island. The crossing is passable most of the day, but extreme high tides can cut off access briefly. Coasteering sessions adjust to conditions, so trust your operator’s scheduling.
Book ahead: Coasteering sessions fill up in summer, especially weekends. Reserve your slot at least a week in advance during peak season.
Weather: This is the Irish Sea coast. Wind and rain are possible any weekend of the year. Pack layers, a waterproof, and the understanding that dramatic weather often makes for better stories.
