Fantastic tour! Seeing the sunset at Mauna Kea is breathtaking. They take you to the visitor's center for acclimation for about an hour (sandwiches they provided were delicious!), then drive you to the summit with a couple of short photo stops in between. They take pictures of you and your group and then send them to you at the end of the tour. On the way down, you stop at the visitor's center again for stargazing (and they give you hot chocolate and cookies!). They set the telescope on the moon the night that we went. I wished they would have also set the telescope on some of the stars. There's one telescope for the whole group to share (for us, there were 6 on the tour that night). My teens and I loved it. They gave us coats, gloves, and offered ski pants (unnecessary).
