Spring Lake Regional Park is a 320-acre recreation area featuring a 72-acre lake fed by local runoff and an interconnected trail network. The park is situated between the Santa Rosa Creek and the foothills of the Mayacamas Mountains. It features a designated swimming lagoon with seasonal lifeguards and a sandy beach area. The park encompasses a mix of oak woodland, grasslands, and riparian habitats. An Environmental Discovery Center offers interactive exhibits on local flora and fauna. Facilities include a multi-loop campground, dedicated equestrian trails, and a boat launch for non-motorized vessels. The park is part of a larger interconnected regional park system, linking directly to Howarth Park and Trione-Annadel State Park. It serves as a primary hub for mountain biking, birdwatching, and regional trail connectivity in Sonoma County.
