Jones Lagoon is a shallow, mangrove-fringed lagoon system located at the southern end of Biscayne National Park in Florida, USA, surrounded by islands including Elliott Key, Adams Key, Old Rhodes Key, and Totten Key. Access for paddlers is unique, as there is no direct launch from the mainland. The primary method is to take a powerboat from the Dante Fascell Visitor Center at Convoy Point, a roughly 30-minute ride across Biscayne Bay, to an anchorage near Hurricane Creek or outside the lagoon itself. From there, paddlers enter the lagoon on their own kayaks or stand-up paddleboards. The lagoon is closed to motorized vessels, creating a quiet paddling environment. The park provides GPS coordinates for suitable anchorage points for private boaters. The water is crystal clear and very shallow, often just inches deep, allowing for excellent visibility of the seafloor and marine life. This shallowness means paddlers must be mindful of tides; on days with high wind, the current can be strong, indicating that tidal flows are a factor to consider. Wind exposure can be significant in the open areas of the bay during the transit and potentially within the lagoon, making conditions more challenging.

The paddling experience is characterized by exploration of a remote network of lagoons, creeks, and channels lined with red mangroves. The area is known for abundant and easily visible marine life, including yellow stingrays, upside-down jellyfish (Cassiopeia), schools of fish, juvenile bonnethead sharks, and loggerhead turtles. It is also listed on the Biscayne Birding Trail, with opportunities to see wading birds, roseate spoonbills, frigate birds, and white-crowned pigeons, though paddlers are cautioned to stay at least 300 feet away from any bird rookeries to avoid disturbance. There are no facilities within the lagoon itself; all trip planning, including bringing food, water, and safety gear, must be completed beforehand. Due to the maze-like nature of the mangrove channels, the park service strongly recommends filing a float plan and, for those without a guide, being prepared with navigational aids to avoid getting lost. The best time of day for paddling is not specified, but guided tours are offered in the morning and afternoon. The overall vibe is one of a secluded, natural wilderness adventure focused on wildlife observation in clear, calm waters, though wind can alter conditions quickly.
