Northern Ireland's only public aquarium and a working seal sanctuary, right on the shore of Strangford Lough — touch the rays and starfish, walk the underwater tunnel and meet the rescued seals, then loose the little ones in the soft play.

  • What you'll see — the marine life of Strangford Lough and beyond: sharks, rays, jellyfish, otters, turtles, tropical fish and a crocodile, an underwater walkthrough tunnel, and touch tanks where you can meet dogfish and stingrays up close.
  • The seals — Exploris runs a seal rescue and rehabilitation sanctuary, nursing sick and orphaned pups back to health before release. You can usually see the resident and recovering seals in the outdoor pools.
  • For the kids — as well as the tanks there's an indoor soft-play area and an outdoor adventure playground, so there's plenty of running-about between the exhibits.
  • How long — allow a half-day; most families spend two to three hours going round, longer with lunch and the play areas.
  • Cost & food — from around £15.95 per person, family tickets in the region of £42, and under-2s go free in the daytime — confirm the current rate when you book. The Kraken Bar & Grill on site is open from 11am daily (last hot food 4pm).
  • A brilliant rain-or-shine day. The aquarium is mostly indoors, so it's just as good in the wet — and if the sun's out, the seal pools, the playground and the Strangford shore make a lovely afternoon either way.
  • Book online to guarantee entry. Exploris advises pre-booking on explorisni.com — the 10–11am slot is a quieter session if you'd rather beat the crowds.

Questions

Before you go

Do I need to book?
Booking online is advised to guarantee entry, as busy days can reach capacity. Head to explorisni.com to book and to check the current prices and times. The 10–11am quiet session is a gentler option if you'd prefer.
Can the children touch the animals?
Yes — the touch tanks let you meet dogfish and stingrays up close, alongside starfish and other rock-pool life. It's the highlight for most young visitors.
Is it good in the rain?
It's ideal — the tanks, the touch pools and the underwater tunnel are all indoors, so a wet day is no problem at all. When it's dry, the seal pools and the outdoor playground add the fresh air.
Will we see the seals?
Usually, yes — Exploris runs a seal rescue and rehabilitation sanctuary, and you can normally see the resident and recovering seals in the outdoor pools. If you ever find an injured or stranded seal on the coast, call the rescue line on 028 4272 8062 (option 2).
Is there food?
Yes — the Kraken Bar & Grill on site is open from 11am daily, with last hot food at 4pm.

All ages enjoy it — the touch tanks, the tunnel and the seals suit younger children especially, and the indoor soft play and outdoor playground keep them busy between the exhibits.

The story

The aquarium on the edge of Strangford Lough

Exploris sits right at the foot of the Ards Peninsula in Portaferry, on the shore of Strangford Lough — one of the richest marine sites in these islands, where the tide pours in and out through the Narrows twice a day and carries an extraordinary spread of sea life with it. That setting is the whole point of the place: rather than an ocean-tank spectacle from somewhere far away, Exploris is built around the creatures that live on your own doorstep, from the dogfish and rays of the lough to the crabs, starfish and anemones of the rock pools.

It grew into Northern Ireland's only public aquarium, and over the years added the tropical tanks, the jellyfish, the reptiles and the underwater walkthrough tunnel that draw families back. But the part that gives it its heart is the seal sanctuary. Exploris rescues sick, injured and orphaned seal pups from around the coast, nurses them back to strength in its rehabilitation pools, and returns them to the wild once they're ready — and you can see the residents and the current patients while you're there.

Add the indoor soft play and the outdoor adventure playground, the Kraken Bar & Grill for lunch, and the little town of Portaferry with its harbour and its ferry across the lough, and you've the makings of a proper, full day out — the kind that works whatever the sky is doing, and that you'll be glad you gave the whole day to.
