Turkey Basin is a significant open-water feature within the Florida Keys backcountry, located between Sugarloaf Key and Marvin Key. It is a shallow saltwater basin characterized by extensive flats, coral beds, and clear water. The primary paddling routes involve crossing the basin, often as part of a trip to destinations like Marvin Key or Snipe Keys from launch points such as Sugarloaf Key. A common access point is the Sugarloaf Key KOA campground, from which paddlers proceed under the US-1 bridge into Bow Channel and then out into Turkey Basin. The basin is exposed and can become quite rough on windy days, with a long fetch that builds chop; a sprayskirt is heavily recommended. Tides are a critical planning factor, as they run strong through the narrow channels between keys and shoals. On very low tides, especially when combined with wind, the water can be blown out, exposing the sea bed for miles and making travel impossible. Paddlers must time trips to work with the tides. The area is part of the Great White Heron National Wildlife Refuge, and while some private keys like Marvin allow limited public use, refuge islands are generally off-limits. On weekends and holidays, Marvin Key is a popular destination for boaters, creating a busy "sandbar party" atmosphere. Navigation across the open basin requires a good map and compass; a GPS is recommended. The crossing offers sightings of sea turtles and passes over lush coral beds.
