What's New in the Florida Keys: Fall 2026 Edition

The Florida Keys continues to evolve, with new dining spots, renovated resorts, improved airport facilities and fresh attractions appearing throughout the island chain.

From Key Largo and Islamorada to Marathon and Key West, the latest developments offer new reasons to explore the Keys, and new ways to experience life in the islands.

Whether you're a longtime resident, planning a visit, considering a second home or researching a move to the Florida Keys, here's what's new and worth watching this fall.

1. Marathon Airport Is Expanding Its Private-Aviation Facilities

One of the Middle Keys' notable infrastructure projects is taking place at Florida Keys Marathon International Airport.

Million Air Florida Keys is investing $4 million in a new 5,460-square-foot passenger facility. The two-story building is targeting completion by late December 2026.

The expansion follows the completion of a separate $5 million fuel farm earlier this year.

Million Air serves private-aviation customers, offering services such as catering, vehicle rentals, pilot facilities and conference space.

Why it matters: The project represents a significant investment in Marathon's private-aviation infrastructure and could improve the experience for business travelers and private aircraft passengers.

The December completion date is a target, so confirm the latest construction status before making plans around the opening.

2. Key Largo Has New Luxury Suites at Baker's Cay Resort

Baker's Cay Resort, Curio Collection by Hilton, has introduced 12 new luxury suites at its 15-acre waterfront property in Key Largo.

The approximately 700-square-foot suites feature private balconies, coastal-inspired interiors and water or partial-water views.

Guests in the new Palm and Paradise suites also have access to a dedicated concierge service for dining reservations and personalized experiences.

Located along Florida Bay, Baker's Cay is an option for travelers seeking a resort experience in the Upper Keys.

Why it matters: The new suites add to the area's luxury accommodation options without requiring an entirely new resort development.

3. Cheeca Lodge & Spa Has a New Owner

Islamorada's iconic Cheeca Lodge & Spa has been acquired by Bass Pro Shops through its nature-based corporate division.

Founded in 1946, the 254-room resort is known for its fishing heritage, long Atlantic pier and golf course designed by Jack Nicklaus.

As of the September 2026 tourism update, the property's conversion plans and timeline had not been announced.

For now, it is best described as a major ownership change rather than a confirmed renovation or redevelopment project.

Why it matters: Cheeca is one of Islamorada's best-known resort properties. Any future changes to its facilities or guest experience will be worth monitoring.

4. Islander Resort Celebrates 75 Years in Islamorada

Islander Resort is celebrating its 75th anniversary in 2026 with redesigned accommodations and expanded recreational amenities.

The oceanfront resort has introduced 114 newly designed bungalows and suites and renovated 25 Bayside Villas.

Its expanded two-acre Seaside Sports area includes a nine-hole putting course, pickleball courts, basketball, volleyball and bocce facilities, alongside equipment for water activities.

The property also offers several dining venues, including Drift on the Beach and Tides Beachside Bar.

Why it matters: The improvements give visitors more recreation and accommodation options while adding to Islamorada's established resort offerings.

5. Hawks Cay Is Preparing to Open Coral Cay Adventure Park

Hawks Cay Resort on Duck Key is preparing to open Coral Cay Adventure Park on December 1, 2026.

The planned 2.5-acre park is designed for resort guests and will feature a 32-foot launch tower, three waterslides, including one approximately 330 feet long, and a splash zone for younger visitors.

Plans also include a sports lawn, climate-controlled arcade, children's activity area and casual dining.

The project is part of a broader resort refresh that includes marina improvements, spa upgrades and the Salt + Ash restaurant from chef Jeremy Ford.

Why it matters: The new attraction could make Duck Key more appealing to families looking for a resort-centered Florida Keys vacation.

The opening date is currently planned rather than guaranteed.

6. Hilton Key West Resort & Marina Has Debuted on Stock Island

Formerly known as Oceans Edge Resort & Marina, Hilton Key West Resort & Marina has joined Hilton's portfolio.

The waterfront property features 175 guest rooms, including 86 suites, along with marina access, six saltwater pools, dining venues and recreational activities.

The resort also provides shuttle service to Key West's Old Town and Historic Seaport.

This is a brand transition and property enhancement rather than a completely new ground-up hotel.

Why it matters: The change adds another established hospitality brand to the Lower Keys and gives visitors an additional waterfront accommodation option.

7. Ocean Key Resort & Spa Unveils a Major Renovation

Ocean Key Resort & Spa in Key West has completed a property-wide renovation.

10. A New Bar Called Misfit Is Targeting a Key West Opening

Misfit, a bar and light-bites concept, is targeting a mid-October 2026 opening at 504 Angela Street in Key West.

The concept is designed as a casual place for drinks and smaller dishes rather than a full-service dinner restaurant.

The owner confirmed the planned opening to What Now Miami in September.

Why it matters: It adds another small independent concept to Key West's walkable historic-district dining scene.

Check current opening information before visiting.

11. John Pennekamp Coral Reef State Park Has a Rebuilt Mangrove Boardwalk

In Key Largo, John Pennekamp Coral Reef State Park has unveiled a rebuilt mangrove boardwalk that winds across the mangrove canopy.

The park is also planning a Discovery Center and Aquarium featuring interactive exhibits and seven saltwater tanks, including a 23,000-gallon centerpiece focused on Florida's Coral Reef.

The project is supported by a $50 million state investment and $2 million from Visit Florida Keys, with completion targeted for late 2028.

Why it matters: The boardwalk provides a new way to experience the mangrove environment, while the planned center represents a larger future investment in marine education.

12. The Turtle Hospital Is Planning a New Medical and Research Facility

Marathon's Turtle Hospital is planning a new facility for treating injured and ill sea turtles.

The proposed facility is located just west of the existing hospital, with a target opening in late 2027.

The organization, which is celebrating its 40th anniversary in 2026, continues its rescue, rehabilitation and educational work.

Its gift shop, which opened in 2025, also provides turtle-themed gifts, books, clothing and souvenirs.

Why it matters: The planned facility could expand the organization's capacity to support sea turtle care and research.

13. Key West's Tennessee Williams Museum Is Preparing to Move

The Tennessee Williams Museum is expected to unveil a new permanent location at 604 Whitehead Street by late fall 2026.

The new location is planned to offer expanded galleries, additional artifacts and photographs highlighting the playwright's life and connection to Key West.

The museum is operated by the Key West Art & Historical Society.

Why it matters: The move would add another cultural attraction to the historic district and provide additional space to tell the story of one of Key West's notable literary figures.

14. Key West's Historic Shrimpboat Sound Studio Has a New Future

Shrimpboat Sound Studio, where Jimmy Buffett recorded for nearly four decades, is planned to become a working recording studio, museum, event space and outdoor drinks bar.

The city-approved concept involves a 10-year lease for the small building in the Historic Seaport District.

The project is targeting an opening by summer 2027.

Why it matters: The plan would preserve a piece of Key West's music history while creating a new cultural destination.

15. October Is Bringing New Food and Cultural Experiences

Not every new development is a building. Seasonal events and culinary experiences are also part of what makes the Keys different in fall.

Taste the Keys, Through October 31

The Upper Keys culinary celebration features participating restaurants offering specially priced lunch and dinner menus.

Two trolley food tours are scheduled for October 15 and October 29.

Details: Taste the Keys

Fantasy Fest, October 16–25

Key West's annual costuming festival returns with the 2026 theme “Musical Icons and Iconic Musicals.”

The event includes themed parties, parades, performances and community celebrations.

Details: Fantasy Fest

REEF Fest, October 15–18

Key Largo hosts REEF Fest, a marine-conservation event combining educational programming, outdoor activities and opportunities to learn about the underwater environment.

Details: Reef Environmental Education Foundation

These events can be useful additions to a travel itinerary, but check official schedules for any changes.

What These Changes Mean for People Considering a Move to the Florida Keys

New restaurants, resort upgrades, attractions and infrastructure projects can provide useful insight into the lifestyle of each community.

Key Largo combines Upper Keys access with marine attractions and luxury resort options.

Islamorada is known for its fishing culture, established resorts and waterfront lifestyle.

Marathon offers a central Keys location, boating access, family-oriented activities and growing aviation facilities.

Key West has the greatest concentration of historic attractions, dining, nightlife and cultural experiences.

These developments do not automatically increase nearby property values. Buyers should evaluate real estate based on comparable sales, property condition, insurance, flood exposure and local market conditions.

However, understanding what is changing in each community can help buyers decide which part of the Keys best fits their lifestyle.

Steve's Bottom Line

The Florida Keys has several developments worth following in fall 2026, from Million Air's airport expansion in Marathon and new luxury suites at Baker's Cay to resort improvements, new coffee shops, dining concepts and planned cultural attractions.

Some projects are already complete. Others have announced target opening dates in late 2026 or 2027, and those schedules may change.

For residents, visitors and prospective homebuyers, the most useful approach is to distinguish what's open today from what's still planned.

The Keys is more than a vacation destination. Its evolving restaurants, hospitality offerings, public attractions and infrastructure help shape what daily life and future visits can look like across the island chain.
