Oso Creek Golf Course (formerly Casta del Sol)
publicOso Creek Golf Course (formerly Casta del Sol) in Mission Viejo is a well-maintained executive-style public course serving South Orange County, winding through the residential hillsides near Lake Mission Viejo. The course plays shorter than a full-length layout but features genuine elevation changes, well-bunkered greens, and a variety of shot demands that make it genuinely engaging. Previously operating as Casta del Sol, the rebrand to Oso Creek reflects the creek that meanders through portions of the layout. It's a popular choice for golfers who want a quality, quicker round without the time commitment of a full 18-hole championship track, and for residents of Mission Viejo's planned community neighborhoods.
The course has served Mission Viejo's master-planned community since the city's development in the 1970s and 1980s, originally operating as Casta del Sol Golf Course. The Casta del Sol name connected the course to the adjacent 55+ retirement community that shares the name. The rebrand to Oso Creek Golf Course was a rebranding effort in the 2010s while retaining the same beloved layout that locals have played for decades.
