This is the best swim facility in all of Orange County, hands down, and it is one of the top aquatic centers in Southern California. Try this on for size: two 50-meter competitive pools and one 25-yard instructional pool, four hours of lap swimming each day, a master's group from 5:45am to 7am daily, and, long course is run throughout the summer months.
M-F 6am-8am, 10am-2pm, 6pm-8pm Sat & Sun 8am-10am
Many competitions are held here, including a few Nationals. Plenty of parking tops it all off, we just wish it was closer to the Orange County hotels (but, it's worth the trip).
