Spend your fourth day getting up close and personal with Florida's gentle giants at the Manatee Observation Center. Located on the Indian River Lagoon, this center offers a chance to learn about manatees and their habitat. Take a guided tour, watch manatees in their natural environment, and explore the interactive exhibits. Afterward, take a boat tour or rent a kayak to further explore the lagoon and its diverse wildlife. End your day with a sunset dinner cruise along the river.
