Cache is not at posted coords. Please follow the detailed steps to reach levels and finally the showdown with the final boss to win & find the cache.
Level One - From parking proceed , on foot or by horse, to the yellow & black diamond sign. At this sign you'll find a brown wooden barrier. Find your way around or over the barrier to access the next level
Level Two - Good work. Now that you have made your way past the barrier start to look for a trail. Trail access is the next level.
