  • The state park in the heart of Santa Rosa is a favorite for hikers and cyclists, offering miles of trails for hiking, mountain biking, and trail riding.

    For wildflower lovers, Trione-Annadel State Park offers a great variety of flowers from early Spring until early Summer, especially on a hike around Lake Ilsanjo. The best months to see the park's wildflowers are April and May, but there are some plants in bloom as early as January and as late as September.

    Open daily from 8 a.m. to sunset

    • Popular with the locals. Watch out for the bikers!

      This is a lovely park, used frequently by locals for hking. But you really, really have to watch out for the mountain bikers. Supposedly bikes should be on designated trails only, but my experience...

    • Great hiking trails

      We hiked around the lake. It was a lovely day, and all of the hikers we met along the trail had excellent pandemic etiquette, keeping their distances and wearing masks.

    • Terrific place to hike

      I’ve been hiking here for many years. There are many trails, some right from Spring Lake Park and many more if going by a map. Lovely Sonoma County landscapes and trees.
