Tennis Day Camp - Beginner and Intermediate, Kids aged 7-16. Every camper learns stroke basics, game strategy, footwork, sportsmanship and receives an ONEC day camp tshirt. The camp is run in a safe and structured environment by responsible and mature tennis instructors. Even Rafael Nadal and Serena Williams don’t play tennis all the day long. At ONEC, we offer structured off-court activities that complement the tennis program every morning and afternoon. Activities include Frisbee golf, capture the flag, and other forms of active and quiet play.
