Mauna Loa is a different Volcano from Mauna Kea or Kīlauea (by Volcano) so many of these reviews are confused. Most tourists do visit Kīlauea and some visit Mauna Kea and few Mauna Loa. That’s a pretty good order of their attraction and ease of...More

This was a hilarious (and sort of dangerous) curvy drive that I would only recommend if you are looking to fill a spare 1.5- 2 hours before or after Mauna Kea. Don't make a special trip here. That being said, we really enjoyed the drive!...More

This is the other summit of the island, at the south of Mauna Kea, and there is a single lane road that gets you there. The ascent is fairly long and we found a few geocaches along the way. It doesn't get to the top...More

We went early for the star gazing and looked around. We did not venture to the top. The look out we hiked to was beautiful. The star gazing was awesome. Definitely worth a visit. It was amazing how many stars we could see.

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.

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.
