Im lucky enough that this is my second time staying here! Sad to say that both times there were empty sites even though they were all reserved.   There is a nice sheltered area for a wind break for dinner, potable water and pit toilets with hand washing station. Plan for chilly and windy weather in the winter and spring.  We stayed here once to save drive time to see the sunrise and the second time after hiking into the crater. Great location for both.  The short hike connected to the campground to see all the tree varieties is cool!
