This was a once in a lifetime experience with a fantastic guide, Wes. He was informative about all things Hawaii, brought great energy to the experience, made sure we felt safe and comfortable at all times, and added some humour! They bring you up to the visitor station at 9000ft to acclimatize (everyone has to do this) for 30mins, we ate our provided sandwiches, then drove up another 30mins to the top. We were up at the top for about an hour, Wes took great pictures of each of the individual groups on our tour (10 people), watched the sunset then went down to a slightly lower mini parking lot to stargaze. Wes gave us hot chocolate and we got to see Jupiter through a telescope (not great definition but you could see a white circle and its 4 moons), and he used a lazer pointer to show us different constellations. We finished with photos in front of the stars, then he drove us back to our initial pickup locations. Overall fantastic experience with awesome guide - HIGHLY RECOMMEND.
