Things to Do in Anglesey: Coastal Walks, Beaches & More

If you're looking for things to do in Anglesey, the island rewards a bit of planning more than most UK breaks. Ynys Môn, to give it its Welsh name, is small enough to cross in under an hour by car but spread out enough that trying to see everything in one day usually means seeing nothing properly. This guide groups the island's best spots by area and by how much time you actually have, with real distances, parking notes and opening hours, so you can build a day or a long weekend that works.

Getting Onto the Island and Getting Around

Anglesey connects to the Welsh mainland via the Menai Suspension Bridge, built by Thomas Telford in 1826 and still one of the most recognisable crossings in Wales. From Bangor, it's a five minute drive across the bridge into Menai Bridge town, which makes a sensible base if you're staying two or three nights.

A car is genuinely the easiest way to get around. Public transport exists between the main towns, but the coastal spots that make Anglesey worth visiting, like South Stack and Llanddwyn, sit well off the bus routes. As a rough guide to driving times: Menai Bridge to Beaumaris is 10 minutes, Menai Bridge to South Stack near Holyhead is 35 to 40 minutes, and Menai Bridge to Newborough Forest for Llanddwyn Island is around 25 minutes.

Coastal Walks Worth the Time

The Isle of Anglesey Coastal Path runs for roughly 130 miles around the entire island and forms part of the wider Wales Coast Path, but you don't need to walk anywhere near that far to get the best of it. Three sections stand out for a half-day walk.

The South Stack stretch, near Holyhead, takes you along clifftop paths with views over the Irish Sea before reaching the lighthouse itself. Getting down to the lighthouse means descending about 400 steps cut into the cliff, then crossing a footbridge, so it's not a route for anyone with limited mobility. The RSPB manages the reserve here and its site has current opening times and any step closures, which are worth checking the morning you go, since weather can shut the bridge with little notice.

Further north, the walk around Carmel Head and the Skerries offers a quieter, flatter alternative with fewer visitors and good chances of seeing seals on the rocks below.

Near Newborough, the path along Newborough Warren toward Llanddwyn Island crosses dunes before reaching a sandy spit that only fully clears at low tide. This is the one walk on the island where checking a tide table before you set out actually matters. At high tide the spit narrows considerably and the walk to the lighthouse at the island's tip takes longer and gets wetter underfoot.

Beaches, by What You're After

Anglesey has enough beaches that picking the right one for the day matters more than picking the "best" one overall.

Benllech Beach is the most straightforward option for families, with flat golden sand, a car park right by the beach and shallow water that's safe for young children at most tide levels. Lligwy Beach, a short drive further along the coast, is quieter and sheltered, good for a slower afternoon.

For watersports, Porth Dafarch and Rhosneigr both have reliable conditions for paddleboarding and surfing, with equipment hire available in Rhosneigr itself during the summer months. Beaumaris Beach is different again, sitting beside the pier and historic town, and it's the departure point for boat trips out to Puffin Island rather than a swimming beach.

History Worth Building a Stop Around

Beaumaris Castle, managed by Cadw, was begun under Edward I in 1295 and never fully completed, which is partly why its symmetrical design is still so legible today. It typically opens daily through the summer months and on a reduced winter schedule, with adult entry priced in the region of £9 to £10. Cadw's own site carries the confirmed current opening hours and price, since both shift slightly year to year.

Plas Newydd House and Gardens, on the Menai Strait and now run by the National Trust, is worth an hour or two if you're interested in the interiors as much as the grounds, which look out toward Eryri (Snowdonia) across the water.

At the northern end of the island, the Copper Kingdom in Amlwch tells the story of Parys Mountain, once the largest copper mine in the world during the 18th century. The mountain itself, with its striking red and orange scarred landscape, is free to walk around and takes about 30 to 45 minutes to circuit on foot.

Wildlife and When to See It

South Stack is the main draw for birdwatching, with guillemots and razorbills nesting on the cliffs from around April through July, and a realistic but not guaranteed chance of spotting puffins in late spring. The RSPB visitor centre there runs shorter opening hours outside the breeding season, so if wildlife is the main reason for your visit, spring and early summer are worth planning around.

Boat trips from Beaumaris out to Puffin Island run through the summer season and give a closer view of the seabird colonies and seal haul-outs than you'd get from the shore.

Practical Details at a Glance

How Long Do You Actually Need

A single full day is enough to cover one coastal walk, one beach and one historic site without rushing, for example South Stack in the morning, lunch in Holyhead, then Beaumaris Castle in the afternoon. A long weekend lets you add Llanddwyn Island, the Copper Kingdom and a proper beach afternoon without cramming the schedule, which matters given how much of Anglesey's appeal is in slowing down rather than ticking off a list.

FAQs

Q1. What are the best things to do in Anglesey?

The best things to do in Anglesey include walking the South Stack or Llanddwyn Island coastal sections, visiting Beaumaris Castle, and spending an afternoon at Benllech or Lligwy Beach. Which combination works best depends on whether you have a single day or a full weekend.

Q2. Do I need a car to get around Anglesey?

It's strongly recommended. Buses connect the main towns, but South Stack, Llanddwyn Island and several of the best beaches are a considerable walk from any bus stop.

Q3. Is Llanddwyn Island accessible at all tide levels?

No. The sandy spit connecting it to Newborough Beach narrows significantly at high tide, so check a tide table before setting out, particularly if you're visiting with young children.

Q4. How long does the walk down to South Stack Lighthouse take?

The descent involves around 400 steps followed by a footbridge crossing, and takes most visitors 15 to 20 minutes down, with longer needed on the way back up.

Q5. Is Anglesey good for a family day trip from the mainland?

Yes. Benllech Beach and the area around Beaumaris both suit families well, with flat sand, nearby parking and short walking distances between attractions.
