MPHC Climbing Gym spans 5,000 square feet of climbing surfaces, challenging newcomers and experienced climbers alike with a variety of walls. One-hour lessons imbue beginners with basic summiting skills, such as how to don the included harness and climbing shoes and tips for communicating with a belayer using a series of winks. Afterward, students are free to explore the more than 60 top-roping routes available throughout the gym, which are redesigned monthly. A massive skylight welcomes the sun’s rays upon the cave area, complete with a 40-foot multistepped lead roof. A 160-foot bouldering route snakes through the gym, underlined by thick crash pads, and two 20-foot squeeze chimneys act as practice grounds for wannabe Santas. Those toting a one-month membership gain unfettered access to the gym and equipment rental, which is open seven days a week.
