American Cruise Line offers "Great Rivers of Florida" cruises in the winter and spring months. The 7-night small ship cruises are round-trip from Jacksonville to Palatka (Florida), Ocala National Forest, Green Cove Springs (Florida), the Tolomato River, St Augustine (Florida) and Amelia Island (Florida).
The St Johns River is the longest in Florida (310 miles long) and is an important part of the natural history of Florida. It's a very slow moving "lazy" river. Ocala National Forest is located between the St Johns and Ocklawaha rivers. It protects the world's largest sand pine scrub forest. Water resources include more than 600 lakes, rivers and springs. Visitors can swim, snorkel and dive in the clear springs year-round.
