In a spa-like setting by a lagoon, Harbor Bay Club offers a panoply of sports and workout options. The 25-meter heated pool is open for free swim, laps, lessons and classes such as water aerobics. The gym features a bountiful array of cardio and strength equipment. Pursue your own routine, work with a personal trainer or take a class – such as spin, zumba, kick boxing, yoga, Pilates or Tai Chi. With 19 courts, tennis rules at Harbor Bay Club. Improve your backhand with lessons from their tennis pros. Sign up the kids for basic instruction or tennis camp and who knows? They may be interested in competing in the East Bay Junior League. Harbor Bay Club is decidedly kid friendly. For daily fun, register for after-school kids club and summer camp. Childcare is available for infants (six weeks) through preschoolers. Ready to relax? Treat yourself to a massage or a facial; get a body wax or a pedicure with non-toxic nail polish. The Clubhouse fits 200 seated and can be rented for special events.
