Biologists estimate that water makes up 65% of the human body, 71% of the planet's surface, and 0% of the R & B group Earth, Wind & Fire. Conquer the planet’s most prevalent liquid with today’s Groupon: for $17, you get a four-hour single kayak rental from Charleston Outdoor Adventures (a $35 value).

Nestled along the creek leading to picturesque Folly Beach, Charleston Outdoor Adventures guides aquatic explorers through serene estuary waters in new kayaks with hands-free steering. After a how-not-to-crash course on paddling, boatswains climb aboard kayaks fitted to each rider’s skill level and wardrobe themselves in a life vest before propelling into the drink on four-hour jaunts across the Lowcountry. Navigate the surroundings with a detailed map of the area bequeathed by COA, glimpsing local sights such as seagulls diving for fish or Atlantic bottlenose dolphins cracking open craft brews with their snouts after a long day at work.
