Showcasing the topography of the lower Suwannee River, Manatee Springs State Park has trails leading around deep sinkholes, walks through ancient forests, and a spring run so clear you can see schools of fish racing down it to the river.

Details
Look into the brilliant boil of Manatee Springs, and step back into the past. Although the popular state park that surrounds it has campgrounds, concessions, and trails, the spring and the spring run are timeless, as crystalline as when William Bartram first paddled across its surface in 1774. “The ebullition is astonishing, and continual,” Bartram wrote, “…a lucid sea green color…throwing up small particles or pieces of white shells, which subside with the waters…”
The aquamarine hue of the spring is from microscopic limestone particles suspended in the water, much like the tint of a glacial lake from “rock flour.”
A deeply shaded campground, trail system, and picnic areas make this a welcome retreat, especially in spring and fall. Do use insect repellent, however: forests along the Suwannee tend to have more than their fair share of ticks.

Any hikes just outside of Marco Island? Or natural springs we can visit without traveling more then 1hr??
Check our Naples page for suggested hikes that are within easy reach of Marco Island as well. As for springs, not in your part of Florida. They simply didn’t form there. The closest spring to you would be in North Port, north of Charlotte Harbor along US 41: Warm Mineral Springs.
