The Complete Guide to Williams Island, Aventura FL

Last updated: April 2026

Williams Island is not a building. It is not a development. It is a private island, 84 acres of manicured waterfront real estate surrounded by the Intracoastal Waterway, Dumbfoundling Bay, Maule Lake, and Little Maule Lake, sitting in Aventura, Florida, 19 miles north of Miami and 11 miles south of Fort Lauderdale.

If you're researching Williams Island for the first time, this guide covers everything: the history, the buildings, the amenities, the lifestyle, and what distinguishes this community from every other luxury address in South Florida.

What Is Williams Island?

Williams Island is a gated, private residential community occupying a man-made peninsula in Aventura, FL 33160. Access is via Island Blvd, a private road with 24-hour security gatehouses at the entrance. Once inside, the island contains 13 residential buildings (nine high-rise towers, two low-rise communities, and two non-residential amenity structures), a private club, a full-service marina, resort pools, 10 tennis courts, a spa, restaurants, and 84 acres of landscaped grounds.

The community is sometimes called "The Florida Riviera", a name given by the original developer, The Trump Group, reflecting the Mediterranean architectural style that defines the island's buildings and landscaping. Barrel-tile roofs, arched loggia entryways, cascading bougainvillea, and a continuous water surround from the entrance canals create a cohesive aesthetic that is unique in South Florida.

Who Built Williams Island?

The land was developed primarily by Julius (Jules) and Edmond (Eddie) Trump, South African-born brothers who founded The Trump Group. Unrelated to Donald Trump, they acquired the property in 1980 for $17.6 million and built most of the community through the 1980s and 1990s. The final two towers, 6000 Bella Mare (2005, WCI Communities) and Bellini (2013, Martin Margulies), were completed by different developers. Read the full story in our history article.

The Williams Island Club

The private club is arguably Williams Island's most important feature. Available exclusively to island residents and their guests, the Club offers fine dining with waterfront views, a casual café and bar, a grand ballroom, a full-service spa and wellness center, a fitness center, six tennis courts (clay and hard), pickleball courts, children's programming, a business center, and a waterfront terrace overlooking the marina.

The Club is where the island's social life happens. Community events, holiday galas, children's activities, and weekend brunches all take place here. Many residents consider Club access the decisive reason to choose Williams Island over a standalone luxury building. For a full breakdown of every amenity, see our amenities guide.

The Marina

Williams Island has a private full-service marina accommodating vessels up to 100 feet. Marina slips are available for purchase or lease by residents. The marina provides direct Intracoastal Waterway access, from which boaters can reach Biscayne Bay and the Atlantic Ocean. Nearly every residential tower on the island includes private marina access as a building amenity.

Price Ranges

As of early 2026, Williams Island has a wide price range. Entry-level condos in older classic towers start around $400,000 to $650,000 for 1BR/1BA units under 1,200 sq ft. Mid-range 2BR/2BA residences in the 1,400 to 2,000 sq ft range typically trade for $700,000 to $1.5 million. Premium buildings, Bellini, Villa Marina, Bella Mare, regularly see transactions above $2 million, with penthouses reaching $5 million or more.

Who Lives at Williams Island?

Williams Island has historically attracted Latin American and European buyers alongside domestic buyers from the northeast and midwest. The community is a mix of year-round residents and seasonal residents who arrive in the fall and stay through spring. Many residents are retirees or semi-retired professionals, though families with children are common particularly in the low-rise communities.

Is Williams Island Right for You?

Williams Island is an exceptional fit if you want: a complete, self-contained luxury residential campus with genuine island seclusion; access to a private club, marina, and resort amenities; a waterfront lifestyle on the Intracoastal; and a range of building types (high-rise towers, low-rise villas, Mediterranean townhomes) within a single gated community.

Williams Island is not the right choice if ocean-front beach access is your primary requirement (Sunny Isles Beach is 2 miles away), or if you prefer the energy of a single boutique building in a walkable urban neighborhood.

For most buyers evaluating luxury condos in Aventura and North Miami Beach, Williams Island deserves serious consideration, and usually turns out to be in a category of its own.
