About Us

Located south of downtown Orlando, Obstacle Ninja Academy (ONA) aims to provide a destination for locals and tourists alike.  With rainstorms and humidity a constant reality, the space was designed to take advantage of a dry, air-conditioned facility.

ONA is open 7 days a week to provide members and guests a safe and entertaining environment in which to challenge their abilities and improve their skills.  Our staff members have competed in American Ninja Warrior, providing useful and authentic insight to help you improve.
