Overview
Tyrella is a flat, two-kilometre run of fine sand at the head of Dundrum Bay, with the Mourne Mountains filling the view to the south. Walk it west to east and, near the far end, St John’s Point lighthouse comes into sight with its black-and-yellow stripes. The bay is sheltered rather than dramatic, so the water stays relatively calm and the beach reads as a family strand more than a surf break. It has flown the Blue Flag for years (accounts differ on the exact start year) and held the Green Coast Award since 2008, both markers of clean water and careful management.
If you’ve only an hour, the walk east towards the lighthouse with the Mournes at your back is the thing to do. Time it for low tide, which widens the sand and exposes the reflective pools that make the beach worth a camera.
The dunes
Behind the shoreline sits a mature dune system, 25 hectares of it, designated an Area of Special Scientific Interest. Because the bay shelters them, these are stable dunes where coastal plants and ground-nesting birds do well. This is one of the more southerly places in Britain and Ireland to find oysterplant, the blue-green shoreline plant, alongside native orchids and yellow horned-poppy on the grey dunes in early summer.
A conservation project, run with volunteers, keeps foot traffic off the most vulnerable areas and replants marram and other native grasses to hold the sand in place. Keep to the boardwalks and marked paths through the dunes; the fenced-off patches are doing a job.
Swimming, walking and wildlife
The sheltered water suits paddling and beginner swimming. Lifeguards patrol the designated swimming zone daily in July and August, with weekend cover through the wider summer, and throw-bags sit along the shore for emergencies. The steady onshore wind also makes the bay a reliable spot for windsurfing, kitesurfing and paddleboarding, and the South East Coast Canoe Trail passes nearby with launch points at Killough.
For walkers, a 2.6 km out-and-back route (about 30 minutes) follows the edge of the dunes as part of the longer Lecale Way. It’s mostly flat and manageable with a pushchair. Bring binoculars: oystercatchers, sanderlings and redshanks work the tideline, and common seals haul out on the rocks offshore rather than on the sand, so a distant view is the norm. In the intertidal zone, the honeycomb worm builds reefs and lugworm casts pepper the flats at low water.
Dogs and horses
To protect water quality, dogs are not allowed on the beach between 10am and 6pm during the bathing season (mid-June to mid-September). Outside those hours and out of season, dogs are welcome on leads. Horse riders can use the beach after 6pm during the bathing season (15 June to 15 September).
Getting there and facilities
The beach is reached off the Clanmaghery Road, which branches from the A2. From Downpatrick, follow signs for the Dundrum Peninsula, about 15 minutes; from Newcastle it’s roughly 20 minutes north on the A2. Public transport is limited, so most people arrive by car.
The site is run by Newry, Mourne and Down District Council. The main car park sits directly behind the dunes, with a car-free zone over the beachfront itself to protect the sand. Parking is free outside the bathing season; charges apply on weekends from Easter to September and daily through July and August (10am to 6pm). Toilets are seasonal, open the same weekends-then-daily pattern rather than year-round, so don’t count on them for an off-season winter walk. A first-aid point operates in peak summer.

- Dundrum Castle – a Norman tower house of around 800 years, a few kilometres off, with good views over the bay.
- Ardglass – further along the Lecale Way, with a castle and a working harbour.
- Tyrella House – the historic estate close to the beach, its buildings spanning Regency to Art Deco, with a private beach, polo ground and equestrian centre (grounds are private, so it’s a look-from-the-road affair).
- Newcastle – a lively seaside town with a promenade and cafés, and a visitor centre for maps and local advice.
