We drove up to the visitors center to have time to see the sunset. After sunset we were able to look through several telescopes to see the moons of Jupiter, the rings of Saturn and a close up view of the moon. In addition while waiting in line for the telescopes we saw satellites cross the sky, shooting stars and... More

This was exciting. We drove to the top of Mauna Loa. It is a nicely paved one lane road, windy, curvy, and up and down. Fun and the views at the top are nice. This isn't for people who get car sick. The elevation at the top is about 11,500 feet.

People write here drive to LOA-not so easy.To MAUNA KEA-YES,but to Mauna Loa-HUGE DIFFERENCE. There is one car black top road to sign for hiking trail-nice scenic drive. From there is "road" almost to the top (500 yards),but even in Wrangler-you will damage undercarriage and it will take you over 3 hours each way once you get on this "road".Also... More

Travelling along the Saddle Road we took the detour to the visitors centre at 9300 feet. A step climb, and decent, in areas but well worth the visit. The tourist centre runs a video about the planets which was very interesting although it seemed to escape the attention of many. Views from the centre were excellent, having visited on a... More

When I went to Mauna Loa Observatory, I had no idea how spectacular the evening sky could be. On the drive up, I saw the sun set above the clouds because I was so high up (I missed the turn off and went to the 14.000 ft. level, by accident) ... when I got to the visitor's station, I was... More

We went at night. The stars were brilliant. You could really see the Milky Way with the naked eye. There were also about 10 telescopes setup with knowledgable volunteers there to help you see other celestial sights. My kids loved looking in the telescopes. If you take little ones. Try to teach them not to touch the telescopes before hand.... More

After 21 trips to the Big Island, finally did this tour. WOW! Amazing! The drive was interesting, as the road was steep and difficult, but well worth everything. Cold! Light headed! Who cares-- what a view. So many stars. DO not miss!
