Miami's 'Billionaire Bunker' is a high-security island that has a 13-person police force for its 42 residents. A real-estate agent got me past the guardhouse - here's what the exclusive community looks like

Indian Creek is a village of just 42 people on a tiny private island in Miami's Biscayne Bay.

It's been nicknamed the "Billionaire Bunker" for its wildly wealthy and high-profile residents, including billionaire investor Carl Icahn, supermodel Adriana Lima, and Spanish singer Julio Iglesias.

The village's 34 homes are built around the perimeter of the island, giving them all waterfront views. The center is occupied by an 18-hole golf course and a country club.

I arrived to the island in an Uber. We were stopped at the guardhouse before even getting onto the island.

Fortunately, my name was on a list of expected guests, so I didn't have a problem getting in.

The Indian Creek Village Police monitors the only entrance to the island.

The village of 34 residents is protected by a private, 13-man police force, according to my tour guide, Nelson Gonzalez, a luxury realtor and the senior vice president of EWM Realty International.

The force even patrols the perimeter of the island from the water.

Indian Creek Village is only accessible by car via a single bridge that spans the waterway from Surfside.

We drove across the bridge and I was dropped off in the driveway of one of the island's opulent mansions, which I was planning to tour.

Homes in Indian Creek are rarely up for sale. Right now, there's only one house on the market: an eight-bedroom, Mediterranean-style mansion for $24 million.

I was able to take a tour and photograph the home because it's for sale, but I wasn't allowed to take photos of any other houses on the island.

Although the $24 million home is the only one on the market, houses in the village have been known to sell without being officially listed.

In February 2019, an Indian Creek estate that wasn't officially on the market sold for $50 million, breaking the record for the most expensive single-family home ever sold in the Miami area.

And it was the second time the home broke that record, after selling for $47 million back in 2012, as Business Insider's Lina Batarags previously reported.

A pristine 18-hole golf course spans the center of the island.

The Indian Creek Golf Course is one of the prime golf courses in Florida, according to Top 100 Golf Courses.

"This is not one of the most accessible venues for the visiting golfer, so you'll need to befriend a member to tee it up on the classical William S. Flynn-designed course here at Indian Creek, which dates back to the 1930s," the website reads.

I wasn't allowed to get out of the car and walk around the island, so I took photos through the windows.

Gonzalez told me the island is high-security and the residents are very concerned with privacy. I spotted one of the private police cars patrolling the island about two minutes into my tour.

The island has just one street: Indian Creek Island Road, bordered by lavish homes on one side and the perfectly manicured golf course on the other.

Most of the village's homes sit behind gates, partially shrouded from view by palm trees and other lush foliage.

High-profile investors, Russian billionaires, professional coaches, models and singers, and even US senators have called Indian Creek Village home.

Supermodel Adriana Lima, former Sears CEO Eddie Lampert, and car dealership tycoon Norman Braman are just a few of the wealthy individuals who have owned homes on the island.

One of the island's most famous residents is Spanish singer Julio Iglesias, who owns several properties on the island, Gonzalez told me.

In 2017, the singer was asking $150 million for four contiguous vacant lots he owns on the island. Together, the properties would offer 800 feet of water frontage.

Puerto Rican singer and actor Ricky Martin has also lived on the island at one point, but it's unclear whether he still does.

His home is "quite small compared to the houses of the area," according to Getty.

Billionaire investor Carl Icahn also calls the village home.

Icahn paid $7.5 million for his 14,000-square-foot Indian Creek vacation home back in 1997, according to Forbes.

Yet another notable resident of Indian Creek is Don Shula, the legendary former head coach of the Miami Dolphins.

Shula and his wife have reportedly lived in a sprawling white house on the island for more than 20 years.

The Indian Creek Country Club, a sprawling Mediterranean-style structure, sits on the island's southwest shore.

"The Indian Creek Country Club is Miami-Dade County's most exclusive, and controversial, private society," Gus Garcia-Roberts wrote in the Miami New Times in 2011.

The club house's facilities include a swimming pool, fitness center, massage and steam room, locker rooms, bridge room, and a marina. It was built in 1929 by architect Maurice Fatio, who designed many of the most famous estates in Palm Beach.

Next to the club house is a massive Banyan tree.

Florida is one of the only places in North America where Banyan trees can be found, but the tree is actually native to tropical Asia.

After my tour, I was driven back out of Indian Creek Village.

While I'd expected a degree of security on the private island, I didn't expect it to be quite at that level, from the 13-person private police force to being screened at the guarded gatehouse and not being able to set foot outside the car or take photos of the homes.

The island is really small: The driving tour took at most 20 minutes, and that was moving slowly with frequent stops.

The most telling detail of my short time on the island is that I don't remember seeing a single civilian on the streets or in the yards — but I saw at least two members of the police force. So, while the level of security is definitely, and understandably, a draw to wealthy residents, I found it to be a bit of a deserted island.
