Since opening in early 2012, Climb So Ill has quickly become a serious competitor to the more-established Upper Limits climbing gym in downtown St. Louis. Climb So Ill is located in the renovated power plant of the former City Hospital complex tucked between Lafayette Square and Soulard. The free, plentiful parking is nice but the complex itself is incredible. Modern colors and architecture blend with the red brick and soaring windows of the original structure to create a bright atmosphere that will make any preservationist proud. The facility itself features a main 55-foot wall with auto belay units, a large bouldering wall and a smaller wall for climbers just starting out. A day pass costs $15 plus gear rental, and a 10-visit pass is $120 (or $180 with gear rental). Memberships are also available for $59 or $75 per month; the more expensive option gets you unlimited equipment rental and access to the 24-hour “training zone” which features various devices to encourage climbing and general fitness. Classes and events such as birthday parties are available, and the mezzanine is a popular place for students to get some studying in during climbing breaks.
