Park Information

Spring Lake Regional Park in Santa Rosa is one of Sonoma County's most popular parks, featuring trails, boating, camping, picnic areas, the Environmental Discovery Center and a seasonal swimming lagoon, water park and boat rentals.



Spring Lake features nearly 10 miles of trails. The main trail is a 2.3-mile paved loop around the lake with views of forested hillsides. The multi-use trail accommodates walkers, runners and cyclists and is ADA accessible. The trail elevation is mostly flat, with a brief incline to the main dam.

Unpaved trails such as Fisherman’s Trail and the Horse Loop intertwine with the paved trail and offer less-traveled routes around the lake. Trails connect to adjacent Trione-Annadel State Park and the city of Santa Rosa's Howarth Park.  


The Spring Lake swimming lagoon features a water park and recreational swimming from Memorial Day weekend through Labor Day. Lifeguards are on duty daily during the summer. The lagoon area includes a sandy beach, lawns shaded by redwoods and multiple picnic sites.

  • The Water ParkThe Water Park features inflatable, floating play structures on the swimming lagoon. Two daily admission sessions are available from 10:30 a.m.-1:30 p.m. and 2-5 p.m. Admission is $10 per person per session. Online reservations are highly recommended. Children must be 6 or older, at least 42 inches tall and know how to swim. Learn more about the Water Park.
  • Swimming: Swimming hours at the lagoon are 10 a.m.-8 p.m. Admission is free. Life vests are available for free use.    
  • Water quality: Water in the swimming lagoon is chlorinated, filtered and tested to ensure quality exceeds state standards.
  • Water Bark dog swim: The Water Bark is a multi-weekend off-leash dog party where pets are invited to play in the lagoon after the summer swim season ends. Purchase Water Bark tickets. For 2022, the Water Bark will be held:
    • Saturday/Sunday, September 10-11
    • Sunday, September 18
    • Saturday/Sunday, September 24-25


Spring Lake is a 72-acre reservoir for boating (no gas engines) and paddling. All boaters and paddlers must wear a floatation device while on the lake. The lake surface is sometimes marked by azolla, an aquatic fern. Azolla growth varies due to weather conditions, and Regional Parks coordinates treatment to have the most lasting benefit for seasonal boating.

  • Newanga Avenue entrance: A year-round paved boat ramp for boats up to 16 feet is at the end of the Newanga Avenue entrance. Trailered boats (electric motors only), kayaks and paddleboards can launch here.
  • Violetti Road entrance: Kayaks and paddleboards can be rented and launched from the parking area at the end of the Violetti Road entrance from Memorial Day weekend through Labor Day. One-hour rentals are $12 per rental, and online reservations are highly recommended. First rental is at 10:30 a.m. Last rental is at 4:45 p.m.


Spring Lake has 31 campsites set amid an oak woodland above the lake. Tent, trailer, and RV campers are welcome. Three campsites feature sleeping cabins

Reservations are required and can be made up to 12 months in advance online or by calling the reservations office at (707) 565-2267 from 10 a.m.-3 p.m. Monday-Friday.

Spring Lake features wheelchair-accessible trails, picnic areas, campsites, and access to the Environmental Discovery Center. Approximately 1.2 miles of the paved Spring Lake Loop trail between the swimming lagoon parking area to the boat launch ramp area has moderate slopes and provides good accessibility. There are a few areas where cross slopes exceeds standards, but they are short stretches of the trail. In addition, large portions of the Fisherman’s Trail & the Bay Area Ridge Trail are accessible.

All-terrain wheelchairs are available between Memorial Day and Labor Day on a first-come, first-served basis. These wheelchairs can be checked out at the lifeguard station at the swimming lagoon. To ensure access, pre-arrange use in advance by calling (707) 539-8092.
