Plenty of country clubs. many local parks that my parents took me to as a kid to play. many golf courses that are public and private. There always seems to be people riding their bike or running on nice days. Mercy Hospital in my opinion is the best hospital in Saint Louis, so the hospital here is amazing. I always stayed active by going to friends pools or to a local member pool, or riding our bikes on bike paths in the wooded areas by the golf courses. There are also tons of local health shops nearby, and tons of places like gyms that you could become a member of and use their facilities. These places include the JCCA, MAC, Elks Lodge #9, Bellerive Country Club, Westwood Country Club, Creve Coeur Golf Course, and theres even an ice arena there that has free skate for the public every wednesday night!
