1 / 2Bouldering Project- Upper Walls
π Wallingford, WA
Upper Walls is Bouldering Project's compact annex gym one block north of the Fremont location, dedicated entirely to bouldering terrain. Known for short, technical, and creative problems that develop grip and technique.
This is hidden gem. Short intense and creative problems. Great for building grip and technique.
π Family Action Verdict
Best for older kids and teens with some bouldering experience who want a quieter, more technical environment than a large gym. The space is compact and problem-focused rather than beginner-orientedβfamilies with young first-timers should start at the main Fremont gym and add Upper Walls once kids are comfortable on the wall.

Overview
Upper Walls sits tucked into a residential block at 3625 Interlake Ave N, operating as a focused bouldering-only space separate from the main Fremont gym. The smaller footprint concentrates the climbing into intense, creatively set problems that reviewers describe as excellent for building grip strength and refining technique. The calmer environment and less crowded walls make it a favorite among regulars seeking quality movement over quantity of terrain.
