AYSO Region 100 is the American Youth Soccer Organization region that covers Kailua and Waimanalo, running a recreational Fall Core season with age divisions from 6U through 19U. Waimanalo District Park is listed among the region’s fields, so Waimanalo families have a league option without driving into town. Registration is handled online, with on-site sign-up events and early-registration discounts in the spring.
