Since it’s impossible to see from any major highway, both residents and visitors tend to be blind to Florida’s vast sweep of mangrove forest fringing the tip of the peninsula.
It is largely protected by a string of public lands stretching east to the Florida Keys, with Rookery Bay NERR anchoring the area between Naples and Marco Island.
A dolphin along a mangrove shorelineOnly those who explore by water are marveled by the sheer size of this incredible, largely shallow estuary, made up of tens of thousands of mangrove-topped islands.
Some of the larger islands, such as beautiful Keewaydin, boast extensive sandy strands cradling an incredible array of seashells.
Gulf of Mexico at Keewaydin IslandWildlife abounds, for the estuary provides everything they need: a nursery for fish, a hunting ground for dolphin pods, a nesting ground for massive flocks of birds.
Hiding in plain sight not far from busy US 41 south of Naples, this extraordinary aquatic preserve provides both paddling routes and nature trails to explore.

Given its size and watery nature, much of the reserve can only be explored by boat, either on a tour or on your own. Kayak rentals are available.
Island campsites tempt those who want to disappear into the mangrove maze. See the reserve map for campsite locations.
