Six Mile Cypress Slough Preserve in Ft. Myers, FL is a must-see haven. A walk through the mile long boardwalk can offer sightings of many of Florida's wildlife in multiple ecosystems.
I visited in the late mornings and saw some amazing wildlife activity. However, after speaking with the volunteers that give tours and station themselves along the boardwalk, sightings of otters, wild boars, birds, snakes & gators, occur throughout the morning and all day.
A new visitor center offers a good place to learn about the preserve, cool off, and share stories with the staff.
