You cross the Menai Bridge, and something shifts. The A55 noise drops away. The water opens up below you — silver or steel-grey or, on a lucky day, that particular shade of Irish Sea green that doesn’t have a name. The mainland is behind you. You’ve got 48 hours and an island that has been surprising people for centuries.
This isn’t a list of things to do. It’s an actual plan, in order, built around how the island works — where the crowds go and where they don’t, when to drive west and when to sit still. Don’t rush it. Anglesey rewards the patient visitor.
Friday evening: arrive and eat well
Cross the bridge, slow down, breathe out. If you’re in time for dinner — and you should be — head straight to Dylan’s in Menai Bridge. It sits right on the Menai Straits waterfront, floor-to-ceiling windows facing the suspension bridge towers. The menu is Welsh through and through: Menai mussels, Halen Môn-seasoned everything, local fish cooked without ceremony. Book ahead in summer. This is the meal that tells you you’ve arrived somewhere worth arriving.
After dinner, walk the Belgian Promenade — a half-mile paved path along the Straits, south of the town centre. It was built by Belgian refugees during the First World War and the view back across the water to Bangor is exceptional in the evening light.
Where to base yourself: Beaumaris (Biwmares) for Georgian charm and easy access to everything on the east coast. Rhosneigr for surf-village energy and direct beach access in the west. Menai Bridge (Porthaethwy) if you want to be central and don’t fancy driving everywhere in the dark.
Saturday morning: Beaumaris Castle and Puffin Island
Get to Beaumaris Castle for opening time — 9:30 a.m. It’s a UNESCO World Heritage Site and one of Edward I’s Iron Ring castles, begun in 1295 and never fully finished. The geometry is extraordinary: a perfect concentric design surrounded by a water-filled moat that still holds water after 700 years. Cadw-managed and well-interpreted. Allow an hour.
Then walk north along the promenade rather than back through the car park — skip the tourist café by the castle entrance — to Pilot House Café for a quick coffee with a view of the Straits, or find Red Boat Ice Cream on the pier. You’re back at the pier for a reason: the Seacoast Safaris RIB departs Beaumaris at around 11 a.m.
The 90-minute tour takes you around Puffin Island (Ynys Seiriol) — an uninhabited tidal island at Anglesey’s far eastern tip. The wildlife here is grey seals hauled out on the rocks, guillemots, razorbills, shags, and cormorants stacked on the cliff ledges like spectators. It’s loud, it smells of the sea, and the skippers know exactly where to position the boat for photographs. You’ll be back at the pier by 12:30 p.m.
One honest note: Puffin Island doesn’t actually have many puffins. The colony was decimated by brown rats and hasn’t recovered. If puffins are your priority, save that for South Stack on Sunday morning — that’s where the real colony is.
Book ahead: Puffin Island trips run April–September and slots fill quickly, especially on summer weekends. Don’t leave booking until the morning.
Saturday midday: lunch in Beaumaris
You’re back from the boat by 12:30 p.m. and you need to eat before the long afternoon walk. Beaumaris has options along Castle Street and the pier area — fish and chips, sandwich cafés, and bakeries. Grab something quick and eat it on the seafront. You’re driving southwest in under an hour.
Saturday afternoon: Newborough and Llanddwyn Island
Leave Beaumaris by 1:15 p.m. and drive southwest on the A4080 — allow around an hour, there’s no rushing these lanes. Aim to park at Newborough Beach by 2:30 p.m., then walk south through the dunes into Newborough Forest. The pines give way to a mile and a half of wide white sand, and at the far end the tidal peninsula of Llanddwyn Island juts into the Irish Sea.
The island has everything: a ruined lighthouse (Twr Mawr, 1845), the atmospheric remains of Saint Dwynwen’s Church — she’s the Welsh patron saint of lovers — Celtic crosses, and a coastal loop trail with views of the Llŷn Peninsula and Snowdonia floating across the water. Allow 2 to 3 hours for the full walk. Check the tides before you go; the crossing floods at high water.
This is the best afternoon on the island. Full stop.
Saturday evening: Rhosneigr
Drive north up the west coast to Rhosneigr. The Oyster Catcher sits above the dunes with a terrace that faces directly west over the Atlantic. Book the restaurant if you can, or grab a spot on the terrace and eat pizza in the last of the sun. The wine list is well-chosen, the service is relaxed, and the sunset from here on a clear summer evening is the kind of thing people move to Anglesey for. If there’s live music, even better.
Sunday morning: South Stack
Drive to South Stack (Ynys Lawd) on Holy Island — 40 minutes from most bases, worth every minute. The lighthouse (1809) sits on a tiny sea-stack connected to the clifftop by a suspension bridge, 400 steps below the car park. The walk down is steep but manageable; the walk back up will remind you about yesterday’s beach.
The South Stack RSPB reserve is home to the largest puffin colony on Anglesey — visible from April to July from Ellin’s Tower seabird centre, which sits at the top of the steps and has telescope views of the nesting ledges. You’ll also see choughs — red-billed members of the crow family — picking along the clifftops, and peregrine falcons if you’re lucky. Even outside puffin season, the cliff scenery is among the finest on the island.
Allow two hours minimum. Bring a windproof layer; it’s exposed up there in a way that feels personal.
Sunday afternoon: one last thing
Three options depending on your energy and inclinations:
Option A (active): Book a surf or kitesurf lesson with Funsport or Gecko Surf at Rhosneigr. Two hours with a decent instructor on a consistent Atlantic break is a better afternoon than it sounds, especially if you’ve never tried it.
Option B (slower): Drive to Brynsiencyn and visit Halen Môn. The sea salt visitor experience covers the full production process — how Menai Strait water becomes the salt that’s in every serious kitchen in the country. There’s a café and shop on site, and tasting the salt on Halen Môn butter with fresh bread is genuinely one of the better culinary experiences on the island.
Option C (back to the sea): One more beach before you leave. Trearddur Bay on Holy Island is sheltered and clear, good for a last swim. Or drive south to Cable Bay (Porth Trecastell) for drama — a narrow cove between headlands that catches the swell and the light in ways that make it genuinely hard to leave.
Practical notes
- Best time to visit: May–September for reliable weather. April–July for puffins at South Stack. Autumn has the best light for photography and the smallest crowds.
- Parking: Pay and display across the island. Bring coins or check for app parking (the RingGo app covers most Anglesey car parks). Newborough Beach fills by mid-morning on hot weekends — no overflow.
- Pack: Layers and a windproof jacket whatever the forecast says. Walking shoes even in summer — Llanddwyn is sand and rock, South Stack is 400 steps of uneven concrete.
- Driving: Nowhere on the island is more than 30–40 minutes from anywhere else. The A55 and A5025 are fast; the coastal lanes are not. Factor in the lanes.
- Mobile signal: Patchy across the west and north coasts. Download offline maps before you leave.
Have a good weekend.
