Casta del Sol is Mission Viejo's premier 55-plus active adult community, a gated enclave with its own amenity infrastructure including two recreation centers, pools, tennis courts, and a full calendar of organized social programming. The median price here runs approximately $955,000, making it the most accessible tier in the Mission Viejo market. The buyer profile is entirely distinct from the rest of the city: retirees, downsizers, and active adults who want community structure, security, and maintenance-reduced living within one of Orange County's safest cities.
