Beaumaris is the prettiest town on Anglesey and one of the most rewarding small towns in Wales. Founded by Edward I at the end of the 13th century — the name comes from the Norman-French beau marais, "fair marsh" — it packs a World Heritage castle, a Victorian pier, Georgian streets and a working seafront into a few compact, strollable blocks on the shore of the Menai Strait, with the mountains of Snowdonia (Eryri) filling the horizon across the water.

It is a town for unhurried pleasures: walking the moat at the castle, taking a boat trip to Puffin Island from the pier, eating well in inns that have been trading for centuries, and watching the light change over the strait from the Green.

Highlights

Inside Beaumaris Castle

Beaumaris Castle

The last and most technically perfect of Edward I’s Welsh castles — a UNESCO World Heritage Site with a swan-patrolled moat, left magnificently unfinished when the money ran out in the 1290s.

Puffin Island off Anglesey

Puffin Island Cruises

Hour-long boat trips from the pier to a seabird sanctuary — grey seals year-round, puffins April to July, and the Menai Strait’s bridges on the longer cruises. Dogs welcome with both operators.

Trwyn Du lighthouse at Penmon Point

Penmon Point

Anglesey’s most photographed corner — the black-and-white Trwyn Du lighthouse of 1838, its tolling fog bell, the Pilot House Café and a 13th-century priory on the lane behind.

The Castle — a World Heritage Site

Beaumaris Castle is often called the greatest castle never built — the last and technically most perfect of Edward I’s Welsh strongholds, left unfinished when the money and attention ran out, and now a UNESCO World Heritage Site (part of the Castles and Town Walls of King Edward I in Gwynedd, along with Caernarfon, Conwy and Harlech). Its concentric walls-within-walls design and water-filled moat make it arguably the most beautiful of the four. It is in the care of Cadw.

The Pier & Puffin Island

From Beaumaris Pier, cruise boats run from spring to autumn out to Puffin Island — a seabird sanctuary with breeding puffins, guillemots, razorbills and kittiwakes, plus a resident colony of grey seals — and along the Menai Strait beneath the great bridges. Two long-established operators, Seacoast Safaris and Starida, sail from kiosks by the pier.

Eat, Drink, Stay

For a small town, Beaumaris eats remarkably well. Ye Olde Bull’s Head Inn has been trading since the 15th century; the Liverpool Arms has poured pints since 1706; the Georgian Bishopsgate House Hotel holds an AA Rosette; and the queue outside Red Boat Ice Cream Parlour is a fixture of Castle Street in summer. See our guides to restaurants, pubs and cafes, and to hotels, guest houses and cottages in and around the town.

Walks & the Coast

The Anglesey Coastal Path (part of the Wales Coast Path) runs right through town — south-west along the strait to Menai Bridge, or north-east to Penmon Point, where the black-and-white Trwyn Du lighthouse stands off the headland opposite Puffin Island. Red Wharf Bay’s vast sands lie beyond.

Plan Your Visit

Start with our one-day guide or the weekend itinerary. Getting here is easy: Bangor is the nearest railway station, with buses across the bridge every 20–30 minutes — details in Getting Here and Beaumaris Without a Car. In late July and early August the Menai Strait Regattas fill the water with sails — the town’s signature spectacle.
