Clark's Ranch Yellow Post Site
This single remote camp site offers an isolated scenic location ideal for tent and car camping or a relaxing picnic far from the crowds. This site is within a short driving distance of the Santa Ana River and Deer Creek. Other than a fire ring for campfires, this site does NOT contain the amenities found at developed campgrounds. There is no water, no restrooms nearby, and no trash containers. Please pack it in - pack it out and Leave No Trace! Site is first-come, first-served. Campfires may not be allowed certain times of the year. Contact the Mill Creek Visitor Center for current fire restriction information and road conditions. (909) 382-2882 This yellow post site is reached via Forest Road 1N64, approximately 1/2 mile past the junction of 1N54 and 1N64. This is a dirt road and high-clearance vehicles are recommended.
