Setting sail from Marco Island, your journey towards Marathon promises an exciting blend of serene cruising and captivating coastal sights. This route, popular among seasoned boaters, offers a taste of Florida’s maritime charm while prioritizing safety and comfort.

Departure from Marco Island: Begin your adventure by leaving from Caxambas Pass, the southern gateway of Marco Island. As you proceed, remember to patiently navigate through the narrow channel markers, maintaining a keen eye on the well-placed aids to navigation.

Navigation and Hazards: While the Gulf waters can be tranquil, look out for sudden changes in weather, especially during the hurricane season. The most prominent hazards in this area include shallow sandbars and shifting channels, so keep a vigilant eye on your depth sounder. Modern boating apps like savvy navvy, Navionics, and AquaMap can be invaluable tools, providing real-time updates and navigational data.
