Santa Rosa - Annadel State Park

6201 Channel Drive

The park, 60 miles north of San Francisco on the eastern edge of Santa Rosa offers miles of trails for hiking, mountain biking, and trail riding.

For wildflower lovers, Annadel 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.

Beautiful park! Awesome views! Unfortunately not a whole lot of camping. WATCH OUT FOR MOUNTAIN BIKES!!! Pretty sure that this park is where 90% of the bad reputation comes from. Every last disrespectful rider on the west coast seems to ride here! Had to lunge to grab my 4 year old out of the way of bikers speeding downhill more than once. Had them come speeding up from behind without warning!

Excellent mountain biking destination! I regularly drive up from Vallejo to ride here. The trails are a good mix of mellow flow and chunky gnar. It's a beautiful park with spacious meadows and mature forests. I'm glad to see it slowly opening back up after the wildfires.

Beautiful state park in Santa Rosa. It's great for hiking, MTB, and even horseback riding. I've been coming here since the 80s. It's still a wonderful getaway. The October 2017 fires impacted about 60% of the park, but the recovery is well underway (*April 2018).

Massive local park. Plenty of great trails and off road space to explore. Seemed like a popular mountain biking destination. Surprisingly not crowded. Would recommend for any level of hiker

Have fun walking around this little lake. Almost every time you'll see deer and maybe even a fox. There's more than one way to get here and they all have great views.
