California is set to open its first new state park in nearly a decade on June 12, 2023. The park, known as Dos Rios, is located in the San Joaquin Valley near the confluence of the Tuolumne and San Joaquin rivers. The 1,600-acre park will offer visitors a glimpse of the valley’s waterways before agriculture, but many activities and amenities will be added in the future. Visitors can currently enjoy guided hikes and use picnic tables and shade structures, with plans for biking, swimming, fishing, and nonmotorized boating in the works. The park’s name is still to be determined, and an official grand opening is planned for later this year.
