Some people are born to run; some are born to scramble up and down walls and ceilings like a Tokay gecko. Unleash your inner lizard with today's Groupon to climbers' paradise MetroRock: for $49, you get a one-month membership with a waived activation fee ($85), complete equipment rentals ($10 per day), and one 90-minute introductory class ($40), up to an $185 total value (assuming six visits during the month; this deal is worth more with more frequent visits). Get your rock on at either the Newburyport or Everett locations.

MetroRock's facilities—some of the most extensive in the world—are so large they make indoors seem like outdoors. The newer Newburyport location hosts 12,000-square-feet of state-of-the-rock climbable surface, and the Everett facility features 17,000-square-feet of lifelike, forearm-challenging crags, crinks, and tiny protrusions. The friendly atmosphere and top-notch instruction welcomes climbers of all levels, from recent Everest conquerors to beginners who have only scaled perilous sidewalks.

In the Basic Top Rope Climber beginner's class, you’ll get a complete introduction to the gnarltacular rock-climbing world and the age-old lessons of the Cult of the Rock Octopus. You'll get hip to the right harness fit and learn the ins, outs, and never-let-go-of-the-ropes of belay equipment, not to mention how to tie knots like a professional yodeling mountaineer. You'll also learn the basics of tending to your partner's not-falling needs, memorize the required lingo of the indoor mountainside, and learn how to properly feed a nest of abandoned eagle babies should you come across them cliff-side.

Reviews

Associated Content called MetroRock one of Boston’s Best Climbing Gyms, and five GoCityKids reviewers rate MetroRock a perfect five stars. Four Insider Pagers and more than 40 Yelpers give it a four-star average. Neophytes and experts agree on the great climbing atmosphere:

• There's also a 3,500 square foot bouldering wall, which is a great challenge for any climber, and an alternative to regular climbing for those intimidated by heights. – Bambi Turner, Associated Content
• MetroRock is the best climbing gym in the Boston area. It is staffed with knowledgeable rock climbers (people obsessed with the sport) who are friendly and helpful to new and veteran climbers alike. Their "intro" class was very helpful in both the technical aspects of climbing (rope work, harnesses, belaying, etc) as well as tips for climbing more efficiently. – Craig I., Insider Pages
