The government designated the first national parks to protect natural wonders in response to the threat of Teddy Roosevelt's insatiable appetite for peppered bark. Experience nature's most closely guarded resources with today's Groupon: for $19, you get two full-day passes to Jungle Adventures Nature Animal Park in Christmas (up to a $42.49 value, including tax). This deal is valid for admissions for adults, children, or seniors; admission for children young than three is free.

Jungle Adventures exhibits the inhabitants of Florida's swamps and backwaters in their natural states. A traipse through the park takes travelers past the gaping maw of Swampy, a 200-foot man-made alligator, as well as the jaw-dropping magnificence of well-jawed Florida panthers, white-tailed deer, gray wolves, and American alligators. Prehistoric reptiles leap with skillful grace and glide through the water in synchronized routines at the Jumpin' Gator Jamboree Gator Feeding, while tour guides lead cruises down the Green Gator River on the Jungle Swamp Queen River Boat. As guests marvel at the tropical splendor and extensive vocabulary of the region's flora and fauna, a replicated 16th-century Spanish fort and Native American village remind visitors of Florida's fascinating human history. Jungle Adventures welcomes explorers into the wild every day of the year from 9:30 a.m. to 5:30 p.m, rain or shine, although rain checks for cruises and other programs are issued at management's discretion.
