Bouldering has been booming. According to data from CBJ’s 2025 Gyms & Trends report, 95% of the roughly 270 bouldering-focused gyms in the United States opened in just the past 15 years. Bouldering gym builds—as opposed to climbing gym builds where roped climbing is the focus—have been on an upward trajectory since practically the start of the century, but especially of late. In both 2025 and 2024, 73% of the new climbing gyms in the U.S. were bouldering gyms—an all-time high for a calendar year.
Last year, Bouldering Project opened the largest new bouldering gym, in Minnesota. But where in the country are the largest bouldering gyms of all-time that are still in operation today? We checked with the gym operators to determine which bouldering gyms are offering the most climbing, compiling a list of the top 10. Below are the 10 largest bouldering gyms in the U.S., based on total square feet of climbing wall surface.
