Visiting a swamp is like visiting your brother at college, in that it requires a sense of adventure and forces Swamp Thing to wash his socks. Keep swamp-dwelling creatures on their toes with today's Groupon: for $10, you get one admission to the Swamp Kids Summer Fun Festival at Billie Swamp Safari in Clewiston (a $20 value). Choose from the following dates:

• Friday, June 24 from 10 a.m. to 5 p.m.
• Saturday, June 25 from 10 a.m. to 5 p.m.
• Sunday, June 26 from 10 a.m. to 5 p.m.

Situated on 2,200 acres of uncultivated Florida everglades, Billie Swamp Safari slakes swamp curiosities with swamp-buggy tours, airboat rides, and wildlife shows. The Swamp Kids Summer Fun Festival packs a full schedule of kid-friendly activities including alligator shows, a bounce house, rock climbing, and train rides.

Also available for festival-day enjoyment are regular features such as a 30- to 40-minute eco-tour on an elevated swamp buggy. Eco-tourists embark on a half-land, half-water ride, during which they careen through forested thoroughfares lined with lush vegetation and land-loafing bison, then drift down shallow waterways brimming with jovial turtles and befuddled fish. Humans, snakes, and alligators can interact at the animal and reptile shows, reigniting fond memories of childhood romps in Grandma’s basement cellar.
