Discover The Underwater World At Atlantis

More than 50,000 marine animals live across the lagoons, tunnels, and exhibits at Atlantis Paradise Island’s marine habitat. Built into the resort’s 141-acre layout on Paradise Island, just outside Nassau, the underwater world here includes walk-through aquariums, open-air lagoons, and predator tunnels that put you eye-to-eye with sharks and rays. For anyone visiting the Bahamas, this is one of the most accessible places to see a wide range of marine life without stepping onto a boat.

This guide covers the main underwater experiences at Atlantis — The Dig, the Predator Tunnel, the surrounding marine habitats, and the extra-cost programs like Dolphin Cay — so you can plan which ones fit your day and budget. Whether you’re staying at the resort or visiting on a day pass, the marine habitats are part of the core experience.

The Dig: Atlantis’s Signature Aquarium

The Dig is the centerpiece of the marine habitat at Atlantis. It’s a walk-through aquarium built around the theme of a lost Atlantean civilization, with tunnels that take you through the middle of the exhibits. Thousands of marine animals live here — including tropical fish, rays, eels, and smaller sharks — spread across a series of connected tanks and lagoons. The underwater tunnels give you a 360-degree view, and the interactive displays along the route let you get closer to some of the smaller species.

The Dig is included with every resort stay and every Atlantis day pass. It’s one of the most popular parts of the marine habitat, and because it’s indoors and air-conditioned, it’s a smart stop during the hottest part of the day. Most visitors spend 30 to 45 minutes walking through the full route. For younger children, the interactive elements and the close-up views through the glass are usually the biggest draw.

If you’re visiting on a day pass from a cruise or another Nassau hotel, The Dig is one of the main reasons to include the marine habitat in your plan. The walk-through design means you don’t need to be a strong swimmer or comfortable in deep water — you stay dry and on your feet the whole time. Head into The Dig early in your visit, before the crowds build up later in the afternoon.

Predator Tunnel and the Shark Lagoons

The Predator Tunnel sits within the same marine habitat complex as The Dig, but it’s a distinct experience. This is an underwater tunnel that runs through a large tank filled with sharks, rays, and other large predatory fish. You walk through the center while the animals swim around and above you — the glass ceiling and walls give the feeling of being submerged with them. It’s the closest you’ll get to the larger marine life at Atlantis without paying for a separate program.

Outside the tunnel, the open-air shark lagoons and stingray pools are scattered along the resort grounds. These are visible from walkways and bridges, so you can watch the animals from above without going through a dedicated entrance. The shark lagoons hold several species of Caribbean sharks, and the stingray pools are shallow enough that you can see them clearly from the edge. These habitats are included with your stay or day pass and don’t require any advance booking.

The Predator Tunnel can feel intense for very young children or anyone uneasy about sharks. The animals are close and the tunnel is enclosed. If your group has mixed comfort levels, start with The Dig and let the younger or more hesitant members decide whether the tunnel appeals to them before committing. The open-air lagoons are a gentler alternative.

Dolphin Cay: Interactive Marine Encounters (Extra Cost)

Dolphin Cay is Atlantis’s dedicated dolphin interaction program, located on the resort grounds. It offers structured experiences ranging from shallow-water encounters to full swims with Atlantic bottlenose dolphins. Unlike The Dig and the Predator Tunnel, Dolphin Cay is not included with a resort stay or day pass — it’s a separate, extra-cost activity that requires advance reservation.

The research doesn’t provide specific pricing or program details for Dolphin Cay, so if this is a priority for your trip, check the official Atlantis website or contact the resort directly for current rates and availability. Booking ahead is strongly recommended, especially during peak season from December through April, when slots fill quickly.

For families considering Dolphin Cay, keep in mind that it adds both time and cost to your day. The programs typically run 30 to 60 minutes, and you’ll need to arrive at the designated check-in point before your session. If your group includes very young children, check the age and height requirements for each program before you book. The shallow-water encounters are generally suitable for younger kids, while the full swim experiences have stricter guidelines.

Beyond Dolphin Cay, Atlantis also offers snorkeling and scuba excursions through external operators — these are not part of the resort’s included amenities and require separate booking. If you’re interested in exploring the underwater world beyond the resort’s boundaries, consider a guided snorkeling trip or a scuba diving outing to the reefs and shipwrecks around New Providence — our guide to Bahamas shipwreck diving covers the best sites.

Planning Your Visit to the Marine Habitats

The marine habitats at Atlantis are included with your stay or day pass, but how you approach them depends on your schedule and priorities. If you’re visiting for a single day — whether as a resort guest or on a day pass — the smartest strategy is to hit The Dig and the Predator Tunnel as a single walk-through during the late morning or early afternoon, when the water park lines are longest and the sun is at its strongest. The air-conditioned tunnels give you a natural break from the heat.

For resort guests staying multiple nights, the marine habitats are easy to visit in short bursts. You can walk through The Dig on your way to dinner, watch the stingrays from the bridge while heading to the beach, or stop at the shark lagoon during a stroll around the property. Because the habitats are spread across the resort, they work well as filler between bigger activities rather than requiring a dedicated block of time.

Day-pass visitors should check the official Atlantis Day Pass page before arriving — passes must be purchased in advance and quantities are limited. The day pass includes the marine habitats, Aquaventure, pools, and beaches, so you can combine your underwater visit with water park time. Allow at least 45 minutes for The Dig and Predator Tunnel combined, plus extra time if you want to linger at the open-air lagoons. If you’re interested in seeing marine life in the wild, the Bahamas offers plenty of options beyond the resort — from spearfishing to reef snorkeling.

What’s Included and What Costs Extra

Understanding what’s included in your stay or day pass is the key to avoiding surprises at Atlantis. The marine habitats — The Dig, the Predator Tunnel, the shark lagoons, and the stingray pools — are all included. So are Aquaventure, the resort pools, and the beaches. What’s not included: dining, drinks, spa services, golf, cabanas, lockers (cashless rental), towel rental for day visitors, and Dolphin Cay.

Atlantis is a cash-free resort. All on-property transactions are cashless, so bring a card or set up a room charge. If you’re arriving by taxi or ferry from Nassau, note that many transportation operators still expect cash, even though the resort itself doesn’t accept it.

For day-pass visitors, the check-in process requires your confirmation, ID, the card you used for purchase, and a signed waiver before you receive your wristband. Lockers are available for cashless rental near the Mayan Temple and the Rapids River entrance — small, medium, and large options are available until 6:30 PM, with a $50 fee for unreturned keys.

If you’re comparing Atlantis to other Bahamas water parks, the marine habitat is a major differentiator. Baha Bay at Baha Mar focuses on slides and a wave pool, but it doesn’t have a comparable aquarium or predator tunnel. The marine habitat alone can justify the cost of a day pass if you’re interested in marine life.

Before You Visit the Underwater World at Atlantis

Is The Dig included with a day pass?

Yes. The Dig and the Predator Tunnel are both included with any Atlantis day pass or resort stay. You don’t need a separate ticket. Just show your wristband or room key at the entrance.

What’s the difference between The Dig and the Predator Tunnel?

The Dig is a broader aquarium with walk-through tunnels, interactive exhibits, and a wide range of marine animals. The Predator Tunnel is a focused shark-and-ray tunnel within the same complex. Both are included and can be visited in one walk.

Can you swim with dolphins at Atlantis?

Yes, through Dolphin Cay. It’s a separate program that costs extra and requires advance booking. Check the official Atlantis website for current prices and availability before your trip.

How much time do I need for the marine habitats?

Plan for 45 minutes to an hour to walk through The Dig and the Predator Tunnel at a relaxed pace. The open-air lagoons are spread around the resort and can be viewed in passing throughout your visit.

Beyond the Tunnels

The underwater world at Atlantis is one of the few places in the Bahamas where you can see sharks, rays, and thousands of tropical fish without leaving the resort grounds. It’s not a substitute for a real reef dive or a snorkeling trip, but it’s a convenient, well-designed introduction to the marine life of the Caribbean — especially for families with young children or anyone who prefers to stay dry. If the underwater world at Atlantis sparks an interest in going deeper, consider a guided scuba diving trip to the shipwrecks and reefs around New Providence.
