Exploris
Exploris is Northern Ireland's only public aquarium and one of the most popular visitor attractions on the Ards Peninsula. Located in Portaferry, a picturesque village sitting at the narrowest point of Strangford Lough, the aquarium offers an immersive introduction to the extraordinary marine ecosystems of the Irish Sea and Strangford Lough itself. The aquarium was established in 1987 and has been a cornerstone of marine education and conservation in the region ever since, drawing visitors from across Ireland and beyond who come to observe native sea life in thoughtfully designed habitats. It was relaunched and rebranded as Exploris following significant investment, reflecting an expanded focus on environmental education and hands-on discovery.
Strangford Lough, which Exploris sits beside, is itself one of the most ecologically important marine inlets in Europe and holds Special Area of Conservation status. The lough is renowned for its remarkable biodiversity, home to over 2,000 species of marine animals, and Exploris acts as a kind of living gateway to understanding that hidden underwater world. Among its most celebrated residents have been common seals and grey seals, which the aquarium has rehabilitated through its seal sanctuary programme. Injured or orphaned seal pups brought in from the wild are nursed back to health and, where possible, returned to the sea — a programme that has attracted considerable affection from visitors and significant conservation credibility.
Inside, the aquarium features a succession of tanks and open pools showcasing creatures native to local waters: spider crabs, thornback rays, conger eels, lobsters, seahorses, and a wide variety of fish species. Touch pools allow children and adults alike to make gentle contact with starfish, anemones, and other intertidal species, giving the attraction an unusual tactile quality that distinguishes it from purely passive wildlife encounters. The architecture is functional rather than grand, but the naturalistic layouts of the displays and the quality of interpretation make for an experience that feels authentic and rooted in the actual marine environment just outside the door.
Portaferry itself is a charming and historically layered settlement. The ruins of Portaferry Castle, a sixteenth-century tower house managed by the Northern Ireland Environment Agency, stand close to the waterfront and are freely accessible. The town has a strong maritime heritage and a lively, if small, social scene centred on its waterfront pubs and restaurants. Just across the lough, the village of Strangford is reachable by a short and scenic passenger and vehicle ferry crossing, one of the oldest ferry routes in Ireland. The drive down the Ards Peninsula from Newtownards, following the eastern shore of Strangford Lough, is widely considered one of the most scenic routes in the whole of Ulster.
For visitors planning a trip, Exploris is open throughout the year, though hours vary seasonally and it is worth checking in advance. The aquarium is very well suited to families with young children, school groups, and anyone with an interest in marine biology or conservation. Portaferry is reached most easily by car via the A20 road south through the Ards Peninsula, or by taking the Strangford ferry if approaching from the west of the lough. Parking is available in the town. The surrounding area rewards those who linger: the Strangford Lough shoreline walks, the nearby Exploris beach, and the abundant birdlife of the lough — including vast flocks of wading birds and wildfowl in autumn and winter — make this a rewarding destination beyond the aquarium itself.
One of the more unusual aspects of Exploris's setting is its position right on the edge of the narrows, where the entire volume of Strangford Lough — one of the largest sea loughs in the British Isles — funnels through a channel only about half a mile wide. The tidal currents here are exceptionally powerful and swift, making the narrows a visually dramatic spectacle at tidal turn, and providing the fast-flowing, nutrient-rich water that helps sustain the extraordinary marine diversity of the lough. This tidal energy has also attracted interest from renewable energy researchers studying tidal stream power, adding a contemporary scientific dimension to this ancient and biologically rich waterway.
