Annadel State Park, Santa Rosa

4.7
#4 of 14 in Parks in Santa Rosa
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’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.  more »
  • Nice place to hike - get away from it all! Seems like a good place to mountain bike too. Trails are well marked and easy to manage.  more »
