Matlacha to Marathon

Starting from the quaint village of Matlacha, known for its vibrant arts scene and Old Florida charm, you’re about to embark on a scenic journey through the beautiful waters of Southwest Florida down to Marathon in the Florida Keys. This roughly 165-mile trip offers the perfect mix of delightful waterfront stops and essential safety considerations for cruisers who appreciate a balance of exploration and careful navigation.

Setting Sail

As you leave Matlacha, ensure you’re familiar with the Intracoastal Waterway (ICW) buoys and markers. Start by heading southwest toward San Carlos Bay. This stretch of water is relatively straightforward, but do keep an eye on the depth as the channels can be shallow at low tide, particularly near the bridge as you depart Matlacha Pass.

Sanibel and Captiva Islands

Once you reach the open waters of San Carlos Bay, navigate towards the east side of Sanibel Island. Sanibel and Captiva Islands are popular for shelling and wildlife. If conditions allow, consider anchoring off the coast to enjoy the beaches. Pay attention to military exclusion zones and speed restrictions near Sanibel Lighthouse.

Fort Myers Beach and Estero Bay

Continue southeast, skirting Fort Myers Beach. Known for its active resorts and waterfront dining, this lively area provides a good stopping point for resupply and entertainment. Estero Bay, just south, can offer a calm anchorage if you need a break or the weather turns unexpectedly.

Naples and Marco Island

Following the coastline southeast, you’ll approach Naples, with its upscale dining and elegant shoreline. Further south is Marco Island, which lies at the northern edge of the Ten Thousand Islands, an excellent waypoint with its pristine beaches and fishing opportunities.

Ten Thousand Islands and Everglades National Park

This area is a marvel of narrow channels and unique mangrove islands. It’s advised to stay discernibly within designated routes and maintain a watchful eye for wildlife, as it’s part of Everglades National Park. Navigation here can be tricky; carrying reliable charts is essential, and apps like savvy navvy can assist in predicting safe passages. Check the weather meticulously, as sudden storms can pose risks here without much open water for escape.

Flamingo Bay and Florida Bay

Upon exiting the tangled wonderland of the Ten Thousand Islands, skirt the edges of Flamingo Bay. Entering Florida Bay, it’s wise to hug deeper waters, as the area is notorious for its expansive and shallow flats. Anchor in deeper lagoons or strategically placed marinas like Everglades City or Flamingo for overnight rests, especially if the day’s travel is arduous.

Key Largo and John Pennekamp Coral Reef State Park

Approaching the Keys, you’ll find the coral waters of John Pennekamp State Park an alluring stop. The underwater park offers exceptional opportunities to snorkel or dive around coral reefs, but always be alert for changing conditions and marine protected areas to avoid unauthorized anchoring.

Marathon Arrival

The journey culminates in Marathon, centrally located in the Keys, offering both fuel docks and full marina services. While this destination marks the end of your trip, it beckons you with various activities, from visiting the Turtle Hospital to exploring the serene beaches of Bahia Honda State Park.

Navigation and Safety Tips

Throughout your journey, remain aware of the ICW markers and local maritime regulations, always maintaining a safe distance from diver flags and abiding by no-wake zones to protect local wildlife habitats. For a boater who values a blend of thoughtful navigation and the discovery of Florida’s natural coastal beauty, this route offers a truly enriching experience. Make sure your vessel is equipped with up-to-date GPS and nav charts. VHF radio communication, marine weather forecasting through either onboard systems or apps, and up-to-date knowledge of tidal conditions are imperative for a safe and rewarding journey.
