Deep Sea World or St Andrews Aquarium: Which Fife Aquarium to Visit?

Of the two aquariums in Fife, pick Deep Sea World for sharks and a bigger outing: its 112-metre underwater tunnel is one of the longest in the world, a visit takes 1.5 to 2.5 hours, and it is a 15-minute train ride from Edinburgh. Pick St Andrews Aquarium for a smaller, family-owned visit built around penguins, meerkats and the four otters of its new Otter Kingdom, which slots into a day in St Andrews. If anyone in your group uses a wheelchair, the choice is made for you: Deep Sea World has ramps all the way through, while St Andrews needs stairs to move between its zones.

Which aquarium to choose

Deep Sea World: sharks over your head

Deep Sea World opened on 9 April 1993 in a disused quarry, Battery Quarry, below the Forth Rail Bridge. It describes its sharks as Europe's largest collection, and the centrepiece is a 112-metre transparent acrylic tunnel, which the aquarium says has the longest underwater moving walkway in Europe. Four large sand tiger sharks live in the tunnel. There is no set shark feeding time, but twice a week divers are in the water preparing to feed them, so with luck you will see them.

Beyond the tunnel, the collection runs from piranhas and stingrays to amphibians and tropical fish. Seals have been part of it since 2005, when an enclosure opened for resident seals and for injured ones rescued by the SSPCA. They are fed daily at 11:30am and 3pm, with a talk from one of the presenters. One current gap: the Temple of Frogs exhibit is closed for essential maintenance.

If you want more than the public route, the Access All Areas tour takes you behind the scenes for 20 minutes at £4.50 per person. For something bigger, the adult shark dive takes over-16s with no diving qualification into the water with the sharks. It is suitable for absolute beginners, lasts two hours including briefing and training, and costs £270 with two free spectators, checked September 2026.

Featured location Deep Sea World Inverkeithing, United Kingdom BIAZA The aquarium is owned by the Spanish company Aspro Ocio Group, which also operates Blue Planet Aquarium and other European sites. Large sand tiger sharks are held, along with other shark species.

St Andrews Aquarium: penguins, otters and meerkats

St Andrews Aquarium sits at the foot of the cliff on the Scores, overlooking West Sands. It is independent and family-owned, with more than 120 species, from penguins and meerkats to tropical fish, sharks and reptiles. Its sharks include a native British species, the starry smooth-hound: a coastal fish, not the big sand tigers of Deep Sea World's tunnel. The Humboldt penguins, which the aquarium calls its most famous residents, live in a cliffside enclosure.

The biggest change came after Storm Babet in 2023: in October that year, tidal swells caused irreparable damage to the aquarium's sea wall. The seals did not stay:

The rebuild has brought new attractions for 2026. Otter Kingdom is home to four Asian short-clawed otters, with large viewing windows onto the water, and it arrived alongside a hands-on Dino Dig fossil excavation and a new outdoor decked area. The Dino Dig is included in your visit. The redevelopment is set to more than double the size of the attraction.

Plan your visit around the feeds: otters at 11am, 12:30pm and 3pm, pygmy marmosets at noon, penguins at 2pm and meerkats at 3:20pm. There is also a penguin feeding experience daily at 4pm, in which you feed the penguins in their enclosure after a private briefing.

Tickets and saving money

Check each aquarium's booking page for the day-ticket price on your date. Beyond that:

• Deep Sea World: tickets come as Standard, Junior (ages 3-12) and Concession, and under-3s go free. The Family of Four ticket bundles two standard and two junior tickets. A Flexi ticket bought online is valid on any one date within six months, so you can buy ahead and pick the day later. One carer goes free with each disabled guest, with proof of carer status. If you live nearby, the aquarium says its annual membership pays for itself after three visits.
• St Andrews Aquarium: annual passes cost £51 for an adult, £42 for a child and £174 for a family of two adults and two children, checked September 2026. Because its cliffside layout creates barriers for some guests, visitors with accessibility needs and their essential carers get reduced admission.

Getting there

Deep Sea World is the easier trip from Edinburgh. Trains run from Waverley and Haymarket stations on the Fife Circle line to North Queensferry, the first station after the Forth Rail Bridge, in about 15 minutes. From the station it is a short walk, but the road goes downhill, so take care, and allow for the climb back up. By car, the aquarium puts it 40 minutes from central Edinburgh and 50 minutes from Glasgow, and parking in its own car park is free.

St Andrews is 30 miles northeast of Edinburgh and 10 miles southeast of Dundee, and it has no railway station of its own. Take the train to Leuchars, then a bus or taxi: Stagecoach routes 99 and 42A/42B connect Leuchars and Dundee with St Andrews, with buses up to every ten minutes. Drivers should enter KY16 9AB in the sat nav, which the aquarium says brings you to the closest parking.

Opening hours

Both open at 10am. Deep Sea World opens 10am-5pm every day except Christmas Day, with last entry an hour before closing, and it keeps shorter hours in winter. St Andrews Aquarium opens 10am-5pm seven days a week, with last admission at 4pm, and closes on 24, 25 and 26 December and New Year's Day.

With kids and accessibility

Deep Sea World is fully accessible for prams, pushchairs and wheelchairs, with ramps all the way through for wheelchairs and mobility scooters. There is no lift, some ramps are quite steep on the way out, and the aquarium asks that wheelchairs and mobility scooters stay off the moving walkway. If you need to pop back to the car, get a hand stamp at reception to get back in the same day. The Bridge Cafe looks out over the Forth Bridge and the seals pool.

St Andrews Aquarium is upfront that it is not fully wheelchair-friendly: moving between its zones requires stairs, and because of the layout of the historic building, the toilets and baby changing are up a flight of stairs too. Children who like getting their hands dirty have the Dino Dig, included in admission.

Other wildlife nearby

To see seals in the wild, go to Tentsmuir National Nature Reserve, southeast of Tayport. Common seals live offshore and grey seals haul out at Tentsmuir Point, one of the few places where you can see both species together; if you spot them, keep your distance so you do not disturb them. Further out, the May Princess sails from Anstruther to the Isle of May almost every day from 1 April to 30 September. The trip takes 4.5 to 5 hours, including 2.5 to 3 hours ashore; about 300 seals live on the island all year, and the best time for puffins is April to the end of July.

For land animals, The Scottish Deer Centre at Bow of Fife, Cupar, keeps 12 species of deer along with wolves, lynx, Scottish wildcat and a European brown bear.
