The park, 60 miles north of San Francisco on the eastern edge of Santa Rosa offers trails for hiking, mountain biking, trail riding, fishing, picnic areas, learning/visitors center and guided tours. For wildflower lovers, Annadel Park offers a great variety of flowers from early Spring until early Summer, especially on a hike around Lake Ilsanjo.
