This is a nice trail, clearly marked most of the way and a gentle incline for the majority of the trail that gets slightly steeper by the end. Observatory at the end is a cool payoff but the accomplishment is a little tempered by the fact that it's possible just drive up. <br><br>There are several dedicated parking spots halfway around the campground loop, do not park in a campground spot unless you want to pay the site fee.
