Austin Social Tennis helps promote the sport of tennis among young adults by creating a recreational tennis community that welcomes casual, beginner and intermediate tennis players. One of the ways we achieve our mission is through the Capital Area Social Tennis League (CASTL), a fun, social tennis league serving the greater Austin area. CASTL is designed for young adults ages 21-39 to meet people and make new friends through the game of tennis. CASTL offers a mix of fun games, challenges, drills, and team-based doubles match play. After tennis, our league players continue the fun at a nearby restaurant/bar for our weekly social happy hours.
