Rock climbers from Miami are a lot like surfers from Omaha: shit out of luck. Northern getaways are one thing, but in a city with topography that looks more like a potato latke than a food pyramid, you also need a good gym. Thank God for places like X-treme Rock Climbing, a 14,000-square-foot warehouse with the tallest walls in Miami-Dade. Routes are marked for all levels of expertise, including a cave for the crazy spider monkey set. Employees — who tend to be superlean and full of energy — frequently re-route walls so there's something new for everybody. Equipment is available to rent for reasonable prices ($5 climbing shoes, $3 harness, $1 Balay device), and first-timers can take a class to get comfortable. Members enjoy free yoga, a fitness center, and wireless Internet along with a sense of community. Girls should check out Wednesday ladies' night for $7 — by far the best one-time deal in South Florida — and almost always a lively evening at the gym. Try a seven-visit punch pass for $76 or a monthly membership for $45. It's cheaper than, well, moving to Colorado.
