St. Clair’s Catholic Mission was at the end of the«Alta Acres» street. There’s a sign off the main highway that says«Catholic Church Sunday Mass 9AM» by Skyline Dr. Follow the sign and it will lead you to the church. We stayed in Three Rivers during our visit to Sequoia National Park. We wanted to go to mass on Sunday but Google/Yelp maps lead us close but not at the exact location. If you follow the sign into Skyline Dr. and make a left on Alta Acres Dr., you will find the church at the end of the street. Was a very nice, friendly, small community. We enjoyed our visit very much!
