So much to see, fairly easy hike, sandals for sure footed or running/hiking boots for the comfort! This was a great day, clear early on and cloudy in early afternoon. Could easily spend 4-5hrs visiting this area. Fun for all ages.

Since the Mauna Kea access road was closed during our visit, we decided to do the much less traveled Mauna Loa Observatory road drive. Good drive, interesting landscape, but nothing really new from the many other lava fields. Nothing to see at the observatory on top and going any further on trail road beyond that requires a heavy duty 4x4... More

You can't miss this place! I've been here several times. A must do on the big island. Put this one on your bucket list and at the top. The most beautiful and amazing sights you will ever see. Just look at the pictures I've posted. I ended up going twice I only a week! I wouldn't steer you wrong... Do... More

My wife and I decided to head up to the observatory on a whim. One of those we are on vacation and feel like we should be doing something. It is a pretty good hike up the mountain and unfortunately it was a cloudy. Isn't. We peered into the telescopes looked around a little bit. When we left the hotel... More

The drive up to the observatory is a bit unnerving! Curves and no guard rails! When we reached the top we really enjoyed the site! Make sure you bring jackets/coats! Much cooler!

If you are traveling the Saddle highway and want to visit, it is a easy though twisty drive. The visitors center has a small gift shop and information center. The observatory was not open to visitors.

This utterly blew us away. We watched the sun set from the summit and then went to the free star gazing at the visitor centre. An utterly beautiful experience and so well done. That this is free is a credit to all involved. Be sure to leave a decent tip - this is how they fund this 💕

We visited on April 28th when the fountains of lava could be seen during the day! The lower trail was closed, but I saw on the news that these fountains had spewed hot debris on the lower observation area. This was a neat museum too.

Best to go after sunset so you can see the glow from the lava. Such an amazing sight! We walked from a park before the observatory then walked up to the observatory. There is also a nice view of the glow from that park. Another great place to see in the Big Island!

A great diversion, but it's above the cloud line. Dress warmly and be prepared for potential cloud cover. A weather-dependent event.
