The Oleta River State Park is a 1,043-acre (4.22 square kilometer) Florida State Park on Biscayne Bay in the municipal suburb of North Miami in Metropolitan Miami, Florida. Adjoining the Biscayne Bay Campus of Florida International University, the park contains one of the largest concentrations of Casuarina trees, an invasive species in the state park system.
The river itself no longer flows to the Everglades, but remains a popular area for canoeing. The park also boasts some of the best wilderness bike trails in the country, and is a frequent host for triathlons and other extreme sports events. There is a beach on Biscayne Bay, kayak rentals, and primitive cabins. Oleta River State Park is also the headquarters to one of the state's five AmeriCorps Florida State Parks chapters.
