Sunset Sailing and Waterfront Evenings

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, casual atmosphere. Both are excellent options for a Friday welcome-to-the-weekend dinner. For a complete list of sunset dining options, see our best waterfront restaurants in Key Largo 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. For those looking for a more spontaneous evening, the Islamorada Morada Way Arts District stays lively on Friday nights with galleries open, boutique shopping, and the Florida Keys Brewing Company tap room serving craft beer in its dog-friendly outdoor courtyard. Note that the official Morada Way Art Walk took place on Thursday, August 20 (the third Thursday of the month), but many galleries and the brewery taproom welcome visitors all weekend long.

Friday Night Live Music

Live music is a Friday night staple across the Keys. In Key Largo, several waterfront venues host local bands playing everything from Jimmy Buffett covers to island rock. Sundowners typically features live music on its deck throughout the evening. In Islamorada, Lorelei Restaurant and Cabana Bar at Mile Marker 82 is a reliable choice for sunset live music with its iconic mermaid statue, tiki bar, and expansive waterfront deck. Marker 88 at Mile Marker 88 also offers live entertainment on Friday evenings with a refined dining menu.

Always confirm music schedules directly with the venue, as lineups can change week to week. Our best happy hours and cocktail bars guide has more on the top spots for evening drinks and entertainment.

Morning: On-the-Water Adventures

For anglers, Saturday morning is prime fishing time. Fishing charters depart early from three major marinas in Islamorada: Caloosa Cove Marina at Mile Marker 73.5, Whale Harbour Marina at Mile Marker 83, and the legendary Bud N' Mary's Marina at Mile Marker 79.5. Bud N' Mary's has been operating since 1945 and is one of the most famous sportfishing marinas in the world, offering everything from backcountry flats fishing for bonefish and permit to offshore trips for sailfish, mahi-mahi, and tuna. August fishing is productive across the reef, with yellowtail snapper and mutton snapper running strong. Our best fishing charters in the Florida Keys guide has details on recommended captains and seasonal targets.

For those who prefer snorkeling, Rainbow Reef in Key Largo offers daily snorkeling trips to the living coral reef formations at Molasses Reef and Grecian Rocks. These are among the most accessible and vibrant reef sites in the continental United States, with water clarity at its peak in late August. Half-day trips typically depart at 9:00 AM and 1:00 PM. John Pennekamp Coral Reef State Park at Mile Marker 102.5 also runs daily snorkeling and glass-bottom boat tours through the protected marine sanctuary. Our diving and snorkeling guide covers the best reef sites and operators.

Paddleboard and kayak rentals are available at John Pennekamp Coral Reef State Park, Curry Hammock State Park near Marathon, and Long Key State Park. The mangrove tunnels at all three parks provide a peaceful paddling experience through shaded waterways, with opportunities to spot wading birds, rays, and small sea turtles. Early morning is the best time to paddle before the heat and afternoon thunderstorms build.

Afternoon and Evening: Live Music and Family Fun

Saturday afternoon brings live music at multiple waterfront venues across the Keys. Sundowners in Key Largo and Lorelei in Islamorada both feature live bands on Saturday afternoons, often starting around 2:00 PM and continuing through the evening. The atmosphere is relaxed and family-friendly during the day before shifting to a more lively evening scene.

For families, Founders Park in Islamorada offers a community pool, a small beach area, a playground, and sports fields. It is a great option for keeping kids entertained while parents relax in the shade. The park is open to the public and has restroom facilities.

Saturday evening, the sunset dining circuit repeats with a different energy. Many visitors make a full evening of it: happy hour at one venue followed by dinner at another. 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, especially for larger parties.

Sunday, August 23

Morning: Beach Time and Brunch

Sunday morning in the Keys calls for a slow start. Sombrero Beach in Marathon (Mile Marker 50) is one of the finest public beaches in the island chain, with soft white sand, calm shallow water, a playground, picnic pavilions, and restrooms. It faces the Atlantic side and offers a more natural beach experience than many other Keys beaches. Arrive early to claim a good spot, as the parking lot fills up quickly on summer weekends.

Anne's Beach on Lower Matecumbe Key at Mile Marker 73.5 in Islamorada is a smaller, more intimate alternative with a scenic boardwalk through the mangroves and shallow, calm water that is perfect for wading. It is a local favorite for a quiet morning by the water.

Sunday brunch is a tradition at several waterfront restaurants. Sundowners in Key Largo offers a weekend brunch menu with fresh seafood, eggs Benedict, and tropical cocktails. Other restaurants throughout the Upper Keys serve Sunday brunch specials, often featuring local lobster and fresh catch preparations. Call ahead to confirm hours and availability.

Also on Sunday, the Florida Keys Farmers Market runs from 10:00 AM to 3:00 PM at 81001 Overseas Highway. This market features fresh local produce, artisan goods, tropical plants, handmade crafts, and Keys specialties. It is the perfect place to pick up fresh Key lime products, local honey, tropical fruits, and island-made gifts. The market has a genuine community feel and is dog-friendly.

Midday: Exploring and Paddling

Sunday midday is an excellent time to explore local shops and galleries in Key Largo and Islamorada. The Morada Way Arts District in Islamorada is walkable and features galleries, boutiques, and the Florida Keys Brewing Company tap room. Key Largo has several marina-side shops and boutiques worth browsing, particularly around the Holiday Isle and Caribbean Club areas.

Afternoon paddleboarding or kayaking through the mangrove tunnels is a quintessential Keys experience. The mangrove trails at John Pennekamp Coral Reef State Park offer a cool, shaded paddle through dense mangrove forests, with frequent wildlife sightings. Curry Hammock State Park in Marathon also offers excellent kayaking conditions with calm Florida Bay waters and scenic island views. Kayak and paddleboard rentals are available at both parks.

Evening: Final Sunset of the Weekend

Sunday evening calls for one last sunset experience before the weekend ends. 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, while Marker 88 in Islamorada offers a more upscale sunset dining experience. Lorelei Restaurant and Cabana Bar is another classic choice for a casual farewell dinner 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 or Islamorada, 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 45 minutes or more to the return drive.

Featured This Week

Regular spiny lobster season is active through March 2027, meaning fresh local lobster is featured on menus throughout the Keys. This is a highlight of the late summer dining scene, with many restaurants offering lobster specials, lobster bisque, lobster mac and cheese, and classic lobster rolls. For the best dining recommendations, check our best waterfront dining in the Florida Keys guide.

John Pennekamp Coral Reef State Park offers daily snorkeling and diving trips to the only living coral barrier reef in the continental United States. Glass-bottom boat tours are also available for those who prefer to stay dry while viewing the reef. The park is open from 8:00 AM to sunset, and advance reservations for tours are recommended during the summer season.

Curry Hammock State Park in Marathon is an excellent destination for a full beach day with kayaking. The park has a beautiful stretch of Florida Bay shoreline, kayak rentals, a short nature trail, and picnic areas. It is less crowded than Pennekamp on summer weekends and offers a more relaxed atmosphere.
