A rock climber, like a social climber, needs to navigate various pitfalls and obstacles in order to make it to the top and secure a piglet play-date with Paris Hilton. Don a harness in the name of hierarchy with today's Groupon: for $39, you get an indoor rock-climbing beginner lesson and one-month membership at Peaks Indoor Rock Climbing (up to a $105 value).

Peaks' indoor rock-climbing playground boasts 60 climbing routes, overhangs, a climbing cave, and leading walls for crack- and crevice-loving climbers, as well as brag-worthy bouldering to challenge climbers of all experience levels. During a one-hour beginner lesson with all rental equipment included, prospective peakspersons learn the techniques of climbing, belaying, and safety to get them rock ready for one month of climbing time. Membership includes harness rental only, but indoor rock climbing presents a safe and exciting mental and physical challenge that, like Scrabble, also offers a great workout.
