GTA 6 Leonida Keys: The Islands Chain, Explained

The Leonida Keys is one of the most-shown districts of GTA 6's Leonida state — a chain of small island communities running south of the mainland, mirroring the real-world Florida Keys. Both trailers feature the Keys prominently, with multiple aerial passes and the implication that boating mechanics will be central to gameplay here in a way no previous GTA has attempted.

Below: what the Keys is, what's confirmed about it, and what to expect.

The geographical reality

The Leonida Keys is modelled on the real Florida Keys — the chain of islands extending south from the southern tip of the state. Geographically it's:

• A long causeway connecting multiple islands
• Mangrove patches between the islands
• Working marinas at multiple stops
• Tourist communities in the larger islands
• A mix of weather — clear-blue waters in calm conditions, dramatic storm-cloud potential

The trailers consistently show the Keys at dawn and dusk — Rockstar's marketing focus on the iconic golden-hour Florida lighting.

What's confirmed

From Trailer 1, Trailer 2, and the official Newswire posts:

• A chain of named islands including a "Gator Keys" reference
• Multiple causeways connecting the islands to the mainland
• At least one marina with boat-buying mechanics implied
• Wildlife — pelicans, alligators, fish (visible in trailer footage)
• Brian Heder's Boat Works & Marina — a confirmed business / location

Brian Heder's Boat Works

The named marina business in the Keys. Brian Heder is one of the named GTA 6 characters (his press-kit screenshots are part of the official Newswire library), and his Boat Works & Marina is a confirmed location.

Implications:

• Boat purchasing / customisation — the Boat Works likely functions like the Auto Shop or Bunker, a player-purchasable business that sells / customises boats
• Boating side missions — the Keys's geography essentially requires boating-as-mission-content
• Cross-game lineage — Brian Heder is similar in narrative function to the Cliffford brothers in GTA V; the Boat Works similar in business function to GTA V's car-dealership properties

Boating mechanics

Both trailers show multiple distinct boats — from small skiffs to luxury yachts. The implication is a deeper boat catalog than any previous GTA. Expect:

• Multiple boat classes (skiff, sport boat, yacht, jet-ski, sailboat, etc.)
• Boating skill in the CJ-stats tradition
• Marina-based safehouses with multi-boat storage
• Open-water side activities (fishing, diving, water-sports)

The 2022 leak referenced fishing mechanics specifically — likely playable in the Keys with rod-and-reel mechanics.

The Keys vs Vice Beach

The Keys and Vice Beach (the urban beach district of Vice City) are distinct districts. Players will likely:

• Spend the early campaign in Vice Beach urban content
• Transition to the Keys for boating-heavy mid-game arcs
• The Brian Heder Boat Works is the bridge between the two — a Keys business that ties the two districts narratively

Real-world templates

Specific Florida Keys real-world references:

• Key Largo (the largest island) — likely the analog for the largest Leonida Keys
• Key West (the southernmost point) — likely a culturally distinct sub-district
• The Seven Mile Bridge — the iconic causeway connecting Marathon to the Lower Keys; almost certainly an in-game equivalent

Wildlife

The Keys are confirmed to have:

• American alligators in the mangroves and brackish water
• Pelicans flying in flock formation along the coast
• Fish in the open water (implied by trailer aquatic footage)
• Manatees referenced in marketing / leaks but not yet confirmed visually

The hurricane question

Both trailers have shown storm-cell formations that suggest dynamic weather, and leaks have referenced hurricane events that flood low-lying Leonida districts. The Keys are the most-vulnerable to hurricane content given their geography.

If hurricanes are dynamic, the Keys will see periodic flooding events that change traversal options and create gameplay opportunities unique to the district.

What it adds to the GTA experience

The Leonida Keys gives GTA 6:

• Genuine boating-led traversal — for the first time, large parts of the map can only be efficiently reached by boat
• Florida Keys cultural specificity — Rockstar leans into the Margaritaville / boating-culture aesthetic
• A counterpoint to Vice City — the Keys are slower, nature-focused, less neon-driven
• Marina business mechanics — extending the asset-property loop established in San Andreas
