Trione-Annadel State Park is a state park of California in the United States. It is situated at the northern edge of Sonoma Valley and is adjacent to Spring Lake Regional Park in Santa Rosa. It offers many recreational activities within its 5092acre property.
The rock formations of Trione-Annadel have played central role in its history: its volcanic origins, the Native American use of obsidian, the early 1900s mining of cobblestones, and modern hikers' appreciation of its volcanic rock outcrops.
These lands were occupied by the Wappo and Pomo people in prehistoric times, who would have primarily inhabited the riparian zones and the marsh perimeter. Annadel includes what some biologists consider the best example of undisturbed northern oak woodlands in existence. Visitors can enjoy the park's diverse wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom.

  • I have hiked and biked all over this park. Wonderful place left for all of us to enjoy by the Trioni family.  more »
  • 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.  more »
