Tree Hill Nature Center spans 50 acres of lush, natural landscape populated with ample walking trails that introduce visitors to Florida's varied flora and fauna. The landscape comprises hilltop and wetland areas that host three ecosystems—Southern mixed-hardwood forest, mixed-hardwood swamp, and freshwater stream—and a peaceful family of bog creatures. Nature lovers can flit through the hummingbird garden, flutter amid the butterfly pastures, stalk native wildlife as it stalks its native prey, or wander through exhibits at the on-site natural-history museum. Visitors can also attend workshops and classes, led by master naturalists who are comfortable discussing the mating habits of birds and bees.

Those who opt for the individual membership receive advance notice and registration for classes, lectures, and events (which require paid admission), as well as free admission to one member event and Family Saturday programs. Nature-curious packs toting the Family Tree membership score all the aforementioned benefits for up to a total of six family members, plus priority registration for programs, camps, and the rent-a-dodo service.
