18

Marker 18 sits along an Everglades observation route where the landscape shifts between dense mangrove edges and open freshwater sloughs. Numbered stops like this one guide visitors through the ecosystem at a manageable pace, highlighting the biodiversity packed into each short stretch. The Everglades is best experienced slowly, and stop 18 is a good reminder of that — the subtle movements of fish just below the surface or a roseate spoonbill wading nearby can make for an unforgettable pause in the journey.
