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

The stars are stunning here. But, there are SO MANY TOURISTS that it takes away from the experience. Car headlights are blinding while waiting in lines to look at telescopes. There was someone "pointing out the constellations" with a laser but it was more uninteresting...More

Be sure to "Get Involved" with the gorgeous area of Hilo. Plan on hiking and walking a little at each site. Incredible, just incredible. :)

We were lucky enough to see the lava erupting. They had several rangers available to answer questions and had camera's set up so you could get a close up view. Many interesting displays set up.

The Mauna Loa observatory on the Big island of Hawaii is something you should not miss! It offers great views a different perspective and scale of the island. I suggest driving up before sunset, and staying at the visitors centre after for some stargazing.

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.
What are the hours of operation and how much does it cost to get in?
