    It was a great experience and totally worth the drive. Remember that you need a 4x4 to get to the top. And try to get there half an hour before sunset. It was pretty cold in May, so don't depend on your shorts and sandals. Bring a warm jacket and even a pair of gloves. Most people stop at University of Hawaii telescope facility.
