Norwegian Cruise Line just released the first real details of Great Tides Waterpark, the six-acre attraction opening at Great Stirrup Cay on September 4, 2026. It is the biggest single addition the private island has ever gotten, and NCL is clearly betting it becomes the reason guests pick a Norwegian itinerary over anything Royal Caribbean or MSC is offering nearby.
The numbers alone put it ahead of most private-island competition: 19 waterslides spread across the site, anchored by The Great Slide, a four-person body slide NCL says is the only one of its kind in the Caribbean. Tidal Tower rises 170 feet and mixes mat, inner-tube, and body slides at different drop heights, while the Breakwater Blaster slides use jet-propelled water pressure to push riders through the course — a setup NCL is calling an industry-first for a cruise line’s private island.
A lazy river that actually tries something new
The Wandering River stretches 800 feet and includes an enclosed tunnel section with lighting and visual effects built in, which NCL is billing as the first immersive river tunnel on a private island. It is a smart move — most lazy rivers are just a loop of water with a current, and giving guests a reason to ride it more than once tends to matter more than raw slide count when families are deciding where to spend their day.
Younger kids get their own space in Splash Cay, a 9,000-square-foot zone with eight smaller slides and water features scaled down from the main park. And for anyone chasing an adrenaline hit rather than a slide, Cliffside Cove offers jumps from 10 and 15 feet — NCL says it is the tallest cliff-jumping setup on any Caribbean private island, and as far as we can tell, nobody else is even attempting this on a cruise-line island right now.
Food, drinks, and what’s actually included
Three new dining venues back up the park: Low Tide Smoke for barbecue, Catch of the Cay for seafood, and Tidal Treats for desserts and ice cream. Two bars, Grotto Bar and Floataway Bar, are covered under the Free at Sea drink package — a detail worth noting, since day-pass pricing for the park itself is not included in that package. Day passes start at $99.99 per person, with kids three and under free, and private cabanas for up to six guests are available at a higher rate. Free at Sea onboard credit cannot be applied toward the waterpark charge, so budget for it separately if you are sailing on a Free at Sea fare.
Getting to the island got easier too. A new two-berth pier means ships no longer need to tender guests ashore at Great Stirrup Cay, which should cut down the usual embarkation bottleneck on port days there.
The bigger picture
This waterpark is the latest and largest piece of a multi-year buildout at Great Stirrup Cay that has already added a multi-ship pier, a welcome center, a pool with a swim-up bar, and the adults-only Vibe Beach Club. It is also arriving a few years after Norwegian paid $840,000 in penalties to the Bahamas’ Ministry of Environment and Natural Resources over development-related violations at the same island during the pandemic — a case that a former employee first flagged and that NCL ultimately settled without contesting. Whatever the regulatory history, the company is clearly not slowing down its investment in the destination; if anything, the pace has picked up.
Norwegian Luna will be the first ship to call at the finished park, arriving September 4 on the tail end of a seven-day Caribbean sailing that departs Miami on August 29. NCL president Marc Kazlauskas framed the release as an early look "ahead of the September opening," and multiple ships across the fleet are scheduled to visit before the end of 2026.
For cruisers who have sailed Great Stirrup Cay before and remember it as the quieter, smaller sibling to Royal Caribbean’s Perfect Day at CocoCay, this changes the comparison. Whether it closes the gap or just gives Norwegian its own version of the same arms race is something we will only really know once guests start posting reviews after the first sailings in September.
