The marine wonders at Portaferry Aquarium begin before you even step through the doors. Perched on the edge of Strangford Lough, Exploris Aquarium serves as Northern Ireland’s only aquarium and seal rehabilitation centre—a window into one of Europe’s most remarkable marine environments. The powerful tidal currents outside move 400 million cubic metres of water twice daily through “The Narrows,” feeding an ecosystem that supports over 2,000 marine species.
These aren’t just exhibits behind glass. From graceful rays gliding through the 250,000-litre Ocean Tank to rescued seal pups recovering in the sanctuary, the marine wonders at Portaferry Aquarium tell stories of conservation, biodiversity, and the unique forces that make Strangford Lough a global marine hotspot.
This guide explores each exhibit zone, the conservation work behind the scenes, and practical information for planning your visit to this unique coastal attraction.

Inside Exploris: Location and Exhibits
From the dramatic underwater tunnel to the working seal sanctuary, Exploris packs remarkable marine experiences into a compact coastal facility. Here’s everything you need to know about visiting, from ticket prices to the star attractions you won’t want to miss.
Getting There and Tickets
Exploris Aquarium sits at 1 The Ropewalk, Castle Street, Portaferry, Newtownards BT22 1NZ. This kid-friendly facility features sea life and reptile exhibits, a working seal sanctuary, educational programmes, and on-site dining. The aquarium opens at 10:00 AM and closes at 5:00 PM daily throughout the week.
You can buy tickets either online or upon arrival. We recommend booking online in advance, particularly during school holidays and summer months, to guarantee admission during busy periods. Pricing typically differs between online and on-site purchases. For example, whilst a child’s entry at the gate costs £12.50, online booking often provides discounted rates of around £10.50. Adult tickets and family packages follow similar pricing structures, with online bookings consistently offering better value.
Free parking is available on-site. The location provides easy access from Belfast (approximately 45 minutes’ drive) and Newcastle (about 40 minutes). For many visitors, the Strangford Ferry crossing from the opposite shore offers the most scenic approach.
The Open Ocean Tank
The centrepiece of Exploris spans an impressive 250,000 litres, housing graceful rays, several shark species, and JC, the beloved rescued sea turtle who has become an ambassador for marine conservation education. The underwater viewing tunnel provides the most immersive perspective—standing beneath tonnes of seawater with marine life gliding overhead creates moments that visitors consistently describe as the highlight of their visit.
The tank’s design allows multiple viewing angles. The ground-level tunnel offers a dramatic overhead perspective, whilst upper viewing platforms provide opportunities to watch feeding behaviours and observe how rays move across the water’s surface. Different times of day bring different activity levels—mornings often see more active swimming patterns as fish anticipate feeding times.
From a content creation perspective, the tunnel’s lighting and curved acrylic present both challenges and opportunities. Professional crews filming for tourism boards typically schedule shoots across multiple time slots to capture varied lighting and activity levels, whilst the controlled environment provides reliable conditions that weather-dependent outdoor locations cannot guarantee.
Seal Sanctuary and Rescue Centre
Since its establishment in 1989, the Seal Sanctuary has functioned as the heart of Exploris’s conservation mission. The facility began with modest resources, but a significant milestone arrived in 1999 with the construction of a purpose-built sanctuary created through collaboration between Ards & North Down Borough Council, Northern Ireland Electricity, and the Northern Ireland Tourist Board.
The sanctuary operates on a rehabilitation philosophy. Its primary purpose centres on treating sick, injured, or abandoned seal pups, with the ultimate goal of releasing healthy animals back into wild populations. Because seal pupping follows seasonal patterns, the hospital experiences periods with no residents followed by intensive care seasons when multiple pups require round-the-clock attention.
Behind the viewing areas, the dedicated team works through a systematic rehabilitation process. Rescued pups typically arrive severely underweight, dehydrated, or suffering from infections. Initial treatment involves tube feeding, medication administration, and constant monitoring. As pups gain strength, they graduate to larger pools where they learn to catch fish independently—a critical skill for survival after release. The entire process typically takes three to six months, depending on the individual seal’s condition and progress.
What to Do if You Discover a Seal Pup
If you encounter a seal pup during coastal explorations:
- Observe from a distance – Seals are wild animals requiring space. Human proximity causes stress.
- Never touch – Physical contact introduces disease risks and human scent that may cause parent seals to reject pups.
- Don’t attempt feeding – Seals require specific diets. Well-meaning feeding attempts often cause harm.
- Don’t move pups into water – Seals naturally rest on beaches. Moving them disrupts behaviour patterns.
- Contact Exploris’s Seal Sanctuary Line – Ring 028 4272 8062 and select option 2 to report concerns.
The Department of Agriculture, Environment, and Rural Affairs (DAERA) provides essential operational support for the sanctuary’s work, ensuring rescue operations meet professional wildlife management standards.
For those documenting conservation stories, the rehabilitation journey—from fragile rescued pup to healthy release candidate—demonstrates practical conservation work in action. Tourism organisations increasingly seek these authentic conservation narratives to differentiate their destinations.
Additional Exhibits
Beyond the flagship Ocean Tank and Seal Sanctuary, Exploris houses diverse exhibits showcasing tropical species and reptiles, touch pools offering hands-on experiences with select marine life, and educational displays explaining Strangford Lough’s unique ecosystem. Interactive feeding times occur throughout the day, providing opportunities to watch keepers work with animals and learn about dietary requirements for different species.

Planning Your Complete Day Out
Maximising your Portaferry Aquarium experience goes beyond simply booking tickets—knowing when to visit and what else to explore nearby transforms a good day into an unforgettable one. From avoiding peak crowds to discovering the best coastal walks and heritage sites around Strangford Lough, here’s your complete planning guide.
Best Times to Visit
Exploris welcomes visitors year-round, but timing strategically can significantly improve your experience. School holiday periods (Easter, summer, and Christmas breaks) see increased visitor numbers, particularly mid-morning through early afternoon. Arriving when doors open at 10:00 AM or visiting after 3:00 PM typically means smaller crowds and better viewing opportunities at popular exhibits.
Seal pup rescue season typically runs from late summer through autumn, when newly weaned pups face survival challenges. Visiting during these months increases chances of seeing active rehabilitation work, though sanctuary operations continue year-round with a different focus depending on seasonal wildlife patterns.
Nearby Attractions and Experiences
Whilst Exploris warrants a full morning or afternoon, the surrounding area offers experiences that justify extending your visit. The Strangford Ferry crossing itself functions as an attraction—this short journey provides opportunities to spot wild seals, seabirds, and occasionally dolphins in their natural habitat.
