They are too rough, however, for ten-speed bicycles. Drinking water is available at the park office and the main parking lot at the east end of Channel Drive. There are a few rattle snakes in the park. Be alert for them as well as poison oak. Hitching posts have been placed alongside the trails.
Closures serve to prevent erosion and user conflicts.
Please contact the park staff in advance of arrival if your horsemen's group is planning to visit the park. Annadel State Park is open daily from sunrise to sunset. For wildflower lovers, Annadel Park offers a great variety of flowers from early Spring until early Summer, especially on a hike around Lake Ilsanjo.
