Choo Choo Diving and Aquatic Center, Chattanooga

Whether certifying scuba divers or teaching kids how to swim, Choo Choo Diving and Aquatic Center's small class sizes ensure students get the most out of their courses. New divers can enroll in the discover scuba class, while more advanced divers can get certifications to become open-water instructors. Meanwhile, at the swim school, kids as young as 6 months old splash in the pool with their parents, whereas older children are separated by age and experience level.
