The incredible secret island theme park & water attraction with beach that you can only visit via cruise ship

A TINY island in the Caribbean is home to a huge theme park and water attraction - and only open to a few thousand a day.

Perfect Day at CocoCay is a private island belonging to Royal Caribbean.

This means only cruise passengers can visit, and it is not open to any other ships.

The 125-acre island is found in the Bahamas and is included on most Caribbean itineraries with Royal Caribbean cruises.

One side of the park features a zip line, wave pool, 13 waterslides including the tallest in North America, and a massive helium balloon ride.

The island's other side has relaxing beach-front cabanas, a swim-up bar, and beach activities like sand volleyball and snorkeling.

Bryan James, who works for Royal Caribbean, recently shared a video from inside the island.

He explained on TikTok: "So there's this theme park on this island in the middle of the ocean you can only get to by cruise ship.

"It has one of the tallest water slides on the planet.

"I live on this cruise ship and we go to this island every single week."

He said the island also has water parks, beaches with cabanas and loads of food and drink to choose from.

Bryan continued: "I really like how on the island everything is connected by these tiny pathways."

He also pointed out a whole new section being built, which will be an adults-only section, open from 2024.

However, previous guests raved about the island on TikTok.

While most on-site activities are included for cruise guests, the more exciting activities will cost you extra.

For instance, the Thrill Water Park, which includes all of the water slides, will cost you $130 to access while snorkeling gear costs $37 to rent.

One person said: "I did that waterslide last summer with my son and it is legit awesome. Maybe the most memorable experience of our cruise."

Someone else agreed: "It was absolutely beautiful me and my cousins freaked out going down the multi person water slide."

Here's what it's like to really spend the day on the island.

And other cruise ships have their own private islands, including Disney's Castaway Cay.

Sun Travel recently visited the Disney island - here's what you can expect.
