Six Mile Cypress Slough Preserve — in Fort Myers, FL

The Six Mile Cypress Slough is one of many preserved and pristine swamplands spread throughout southwest Florida. The highlight of the preserve is the 1.2-mile (1.9 kilometer) boardwalk, a wood-planked corridor that runs through the 2,200-acre (890 hectare) wetland, where guests can see alligators, wild boar, otters and much more. During the dry season (October to June), birds like herons and egrets flock to the flag ponds which make it a perfect place for birders. There are guided tours year-round, and self-guided tour brochures in the LEED-certified interpretive center.
