It was meant to be a national park, set aside by developer Barron Collier during his push to create the Tamiami Trail across the Everglades.
The Federal government wasn’t interested, so the state of Florida stepped in and created Collier-Seminole State Park, which opened in 1947.

About the Park
When Barron Collier died in March 1939, he was Florida’s largest landowner.
The state had paid him in vast tracts of land for making good on his promise to drain Southwest Florida for development while building the Tamiami Trail.

In addition to viewing the Bay City Walking Dredge, one of the original dredges used by Collier’s workers to build the highway, and several other historic features, this park is about the wilderness.
