Mankind's feeble climbing skills and inability to digest delicious tin cans are two ways in which evolution left humans inferior to goats. Channel an inner mountain goat with today's Groupon: for $45, you get an Intro to Outdoor Climbing class from California Climbing Company (a $100 value).

California Climbing Company's staff of safety-oriented, First Aid- and CPR-certified instructors imparts sierra-scaling skills to eager climbers. The Intro to Outdoor Climbing class requires no prior experience, so newbies can take the challenge without having scaled plateaus, mesas, or oversize anthills. Classes take place in a number of outdoor locales; students can elect a preferred location, just as they specify their ideal lesson plan. Lasting four to six hours, classes give students thorough instruction, plenty of practice, and a perfect excuse for missing their mailman's piano recital. Though climbing equipment is provided, California Climbing Company asks that all students wear comfortable shoes and long shorts or pants and bring sun protection, snacks, and three or four bottles of water.
