Named for the dwarf palmetto plants found throughout the park, this 289-acre riparian area resembles the tropics and attracts more than 200 bird species. A historic pump forces artesian water into a 1930s-era cistern and water tower. The San Marcos River flows through the park, making it ideal for canoe trips. The park also features a network of trails and boardwalks.
