San Diego's first and only competitive American Ninja Warrior gym for kids, KidWonder Pacific Beach occupies a family-friendly training space at 929 Garnet Ave, 92109. This Black-owned, women-owned business acquired the former G3Kids Pacific Beach location and filled it with AAI beams, trampolines, a Tumbl Trak, a foam pit, uneven bars, and a spring floor. Younger siblings not yet ready for the ninja course can start their early learning journey at Seaside Preschool elsewhere in Pacific Beach. Classes cover ninja warrior obstacle training, gymnastics separated by age group, Pre-K prep, after-school programs, and seasonal camps that emphasize five character pillars: Honor, Integrity, Responsibility, Perseverance, and Courage. Camp Director Kim Bryant, recognized as a Pioneer in Fitness by San Diego Magazine, and coach Staci Wildman, a former LSU gymnast and four-time Level 10 National Championships qualifier, lead the instruction alongside a staff of trained coaches. The Pacific Beach facility is one of three KidWonder locations, with additional gyms in Linda Vista and Encinitas. Open gym sessions, birthday party packages, and family discount pricing make the space accessible for drop-in visits as well as committed athletes. After a high-energy class, families often walk along Garnet for a sweet reward at Pacific Beach Ice Cream Co. nearby. Nike Gymnastics Camp has also partnered with KidWonder to host intensive training sessions at this Garnet Ave location.
