Welcome to Rio Vista

Rio Vista is an early California city, nestled on the banks of the Sacramento River. A warm small town atmosphere yet close to all major highways. Only one hour to the Bay Area and one hour to Sacramento. Some says it’s the best kept secret in California. It’s a great place to raise children and retire too!

Rio Vista is home to Trilogy—a stunning Shea Homes active adult community just 2 miles from downtown. The peaceful tranquility of Trilogy is just what you’ve been looking for. Live in a gated community with people who share your interests, and see why this place is fast becoming one of the most sought after active adult communities in Northern California.
