As of 2016, things to do at the Ellie Schiller Homosassa Springs Wildlife State Park include observing the manatees in the main spring and taking part in a Wildlife Encounter program featuring snakes and other native animals. Boat tours from the visitor center to the west entrance provide an overview of the park. Bird watching, hiking, picnicking and geo-seeking are all common activities at the park.
The park offers three manatee programs per day. Visitors can view the West Indian manatees, a protected species, from a special underwater observatory. The boat tours get visitors out into the wilder part of the park. Native Florida animals that live in the area include alligators, crocodiles, black bears, bobcats and white-tailed deer. Guests may also find more manatees swimming in the river.
Bird watchers may want to head for the Pepper Creek Trail, a 3/4-mile paved walkway that is accessible by wheelchair. Each month, the Citrus County Audubon Society leads group bird walks. Covered picnic pavilions are located in the Garden of the Springs, near the main spring and next to the Alligator Lagoon.
Geo-seeking, also known as geocaching, is an activity that uses GPS devices. One person hides a cache, marks it on the GPS, and leaves it for the next person to find. The finder takes a treasure out of the box and replaces it with something else. Each finder signs a logbook inside. Caches are found throughout the park.
