Sunset Sail or Waterfront Dinner in Key Largo and Islamorada

Friday evening in the Florida Keys is all about sunset and the water. Sunset sailing charters depart from marinas throughout Key Largo and Islamorada, offering a memorable way to watch the sun sink into Florida Bay. Many operators run two-hour cruises with drinks and light snacks included. Book in advance, as Friday night charters fill up quickly during the summer season.

If you prefer to stay on land, waterfront restaurants across the Upper Keys serve dinner with front-row sunset views. Sundowners in Key Largo at Mile Marker 103.9 offers a sprawling outdoor deck with direct sunset sightlines over Florida Bay, a full raw bar, and a lively happy hour crowd. Sharkey's at Mile Marker 93.7 is a classic Keys dock-and-dine spot with fresh seafood, cold drinks, and a relaxed atmosphere. For a complete list of sunset dining options, see our best waterfront dining in the Florida Keys guide.

Dinner cruises also operate from several marinas, combining a multi-course meal with a sunset sail. These typically run from 5:30 to 7:30 PM and require advance reservations.

Fresh Seafood at a Keys Fish Shack

No Friday in the Keys is complete without fresh seafood from one of the legendary fish shacks scattered along the Overseas Highway. Whether you are after a casual lobster roll, stone crab claws (in season), or a fresh catch-of-the-day sandwich, the fish shacks of Key Largo, Islamorada, and Marathon serve up the real taste of island living. For a curated list of the best spots, check our guide to waterfront dining in the Florida Keys.

Saturday, August 29

Morning: Marinelife Rally Key West

Saturday morning features the Marinelife Rally Key West, running from 9:00 AM to 11:00 AM. The demonstration starts at Mallory Square and features a police-escorted march down Duval Street, finishing at the Southernmost Point Buoy plaza. The rally demands restored Endangered Species Act protections for Gulf marine life, urging Congress to pass the Protect Gulf Life Act and reinstate safeguards for sea turtles, corals, and marine mammals. The event is organized alongside the Endangered Species Coalition. Both Mallory Square and the Southernmost Point Buoy plaza remain open to the general public during the gathering. Expect rolling street closures along the Duval Street route with KWPD escort.

Midday: Snorkeling at John Pennekamp and Diving the Spiegel Grove

For those spending Saturday in the Upper Keys, the water conditions are ideal for snorkeling and diving. John Pennekamp Coral Reef State Park at Mile Marker 102.5 in Key Largo offers daily snorkeling trips and glass-bottom boat tours through the protected marine sanctuary. The park is the only living coral barrier reef in the continental United States, and late August water clarity is at its peak. Half-day trips typically depart at 9:00 AM and 1:00 PM.

Advanced divers should consider a trip to the Spiegel Grove wreck off Key Largo. This 510-foot former Navy landing ship dock was intentionally sunk in 2002 and has become one of the most famous wreck dives in the country. It sits upright in 130 feet of water and is home to abundant marine life, including goliath grouper, barracuda, and schools of tropical fish. Several dive operators in Key Largo run Spiegel Grove trips daily. For a full guide to reef sites and operators, see our diving and snorkeling guide.

Afternoon and Evening: Live Music at the Key West Theater

Saturday evening brings a special performance by Reggae Lou & The Kind Budz at the Key West Theater. Known for their infectious island rhythms and high-energy live shows, this is a must-see for reggae fans and anyone looking for a fun evening out in Key West. The Key West Theater is located at 512 Eaton Street in the heart of Old Town. Tickets and show times are available through the venue.

For those staying in the Upper Keys, Saturday evening sunset dining is a tradition. Sundowners and Sharkey's in Key Largo, Marker 88 and Lazy Days in Islamorada, and Castaway Waterfront Restaurant in Marathon all draw crowds for Saturday night dinners with sunset views. Reservations are strongly recommended.

Sunday, August 30

Morning: Islamorada Farmers Market

Sunday morning calls for a slow start at the Islamorada Farmers Market, running from 10:00 AM to 3:00 PM at Mile Marker 81 (Oceanside). This market features fresh local produce, artisan goods, tropical plants, handmade crafts, and Keys specialties. Browse stalls for fresh Key lime products, local honey, tropical fruits, and island-made gifts. Parking is free, and the market has a genuine community feel. It is the perfect place to pick up souvenirs, ingredients for a beach picnic, or a tropical plant for your vacation rental.

The Morada Way Arts and Cultural District in Islamorada is also worth a visit on Sunday, with galleries, boutique shops, and the Florida Keys Brewing Company tap room open for afternoon visits.

Midday: Lazy Paddle Through the Mangroves

Sunday afternoon is ideal for a lazy paddle through the mangrove tunnels. The mangrove trails at John Pennekamp Coral Reef State Park in Key Largo, Long Key State Park, and Curry Hammock State Park near Marathon offer peaceful, shaded waterways through dense mangrove forests. Early morning or late afternoon is the best time to paddle before the heat peaks, with frequent wildlife sightings including wading birds, rays, and small sea turtles. Kayak and paddleboard rentals are available at all three parks.

Backcountry Fishing Trip

For anglers, a Sunday backcountry fishing trip is a quintessential Keys experience. Backcountry fishing targets bonefish, permit, and redfish in the shallow flats and mangrove creeks of Florida Bay. Several experienced guides operate out of Key Largo and Islamorada, offering half-day and full-day trips suitable for all skill levels. August conditions are generally excellent for flats fishing, with clear water and active fish. For recommendations on captains and seasonal targets, see our best fishing charters in the Florida Keys guide.

A lazy paddle through the mangroves or a backcountry fishing trip rounds out the weekend before the final sunset.

Evening: Final Sunset of the Weekend

Sunday evening calls for one last sunset experience before the weekend ends. For a quieter farewell to the weekend, any bayside restaurant or beach with a westward view serves as a perfect vantage point. In the Upper Keys, Sundowners remains a go-to farewell spot. In Islamorada, Marker 88 and Lorelei Restaurant and Cabana Bar offer classic sunset dining experiences with live music.

A note on traffic: Sunday afternoon and evening northbound traffic on US-1 builds significantly as weekend visitors return to the mainland. If you are driving north from Marathon, Islamorada, or Key West, plan to leave by early afternoon or wait until after 7:00 PM to avoid the heaviest congestion. The Overseas Highway is the only road in and out of the Keys, and summer weekend traffic can add an hour or more to the return drive.
