The 210,000 square-foot campus, which sprawls across forty-five acres, accommodates the facilities to make experiences at OMHS the best that it can be. Students can conduct experiments in any four of the science labs or take computer classes in the two computer labs. They can watch plays in the state-of-the-art auditorium which seats 1,000 people, and eat lunch in the "Eagles Landing Cafe," featuring four different cuisine lines.

Sports facilities on campus include a practice gymnasium, a competition gym seating 2,000 fans, baseball and softball stadiums, a band practice field, and soccer practice fields. A multi-purpose stadium, seating 5,000 spectators, was also built on Hwy. 119 to house the football, soccer, and track and field events. Each of these facilities allow Oak Mountain High School students the opportunities to practice and compete on their own "turf".
