Unfortunately, it was voggy (fog + volcanic stuff) when we arrived at the foot of the drive up to the observatory -- which is a mile or so before the drive up to Mauna Kea on the other side of the road when going East...More

The drive to the top of Mauna Kea is long and bumpy; parts of it not paved, but it is so worth it. The views along the drive of the clouds below are remarkable. It is extremely windy at the top, so we took some...More

Star gazing at it's finest. Bundle up because it gets extremely cold when the sun sets but so worth the temps.

long winding drive on poorly maintained road to reach observation area and found view that was less rewarding than what you will find at other locations. if you're into extreme hiking, there's a trail that you can reach at the observation level.

Mauna Kea is where tours take you to the multiple observatory area. Mauna Loa is a paved one lane, 20 MPH access road to a weather obsevatory. I took the drive just to do it. It's a good condition roller coaster road that tricks you...More

There are tours by appointment only. We did not do a tour. There are plenty of state park volunteers who are very knowledgeable. There are telescopes set up to see planets and stars. It varies during the year.
