Happy 3rd annual National Fitness Day Shanghai! In celebration of everything healthy, today you can go check out the Oriental Sports Center for free, along with 50 other public stadiums and gymnasiums around the city. But it gets better! The Oriental Sport’s Center’s outdoor diving pool will be open to the public not only today, but all month long! Go mess around in the water for free until September 7. Since this offer managed to combine two things that are both screamingly popular in China (swimming and free stuff) they suggest you call ahead and reserve time at the pool if you’re interested. They only allow 200-300 people in per 90 minute session, but you can call ahead to reserve (call 20238305 or 20238316, or send an SMS to 106 573 000 168.) Opening hours are from 9:30 – 12:30 (two sessions) and from 13:30 to 17:00 (three sessions.) Weekday morning sessions are probably your best bet. If you do call/text ahead, they ask that you include name, number, how many people (up to three) and session time.
