According to the Pinellas County website, 400-acre Sawgrass Lake Park in St. Petersburg features “one of the largest maple swamps on the Gulf Coast of Florida.” We strolled along the mile-long boardwalk at Sawgrass Lake Park on a sunny Sunday morning and viewed an alligator, some turtles and even a yellow-crowned night heron. Sawgrass Lake Park also offers an observation tower, picnic shelter, restroom. Admission is free.
