We are huge astronomy fans and we really wanted to drive to the top to visit the W.M. Keck Observatory telescopes. We rented a 4x4 to be safe and were pleased that we did. At the visitor center at 9000 feet you feel the high altitude. At the top at over 14,000 feet I really was feeling the altitude. Be... More

There are numerous signs warning that the road up from the visitors center is dangerous and they recommend that you take a commercial tour mini-bus from that point up. I was skeptical that the warning was just to help the tourism business, but my wife was spooked and opted to wait at the center. I drove up in my rental... More

It was very nice to at least go inside one of the observatories while we were atop Mauna Kea. While you didn't go up to any of the telescopes, you were able to see all the vast equipment inside. And some nice restrooms as well.

We weren't able to go to the mountaintop and see the actual mirrors/lenses. But the visitors area in Waimea had amazing photos and the guide there showed us some of the most amazing work the Keck Telescopes did. It is worth 30 minutes to see the awesome science happening in Hawaii

Was not able to drive to the top of Mauna Kea, but visited the Keck Observatory Offices lobby in downtown Waimea which had many displays and gifts and lobby host Liz gave us a complete run down on activities current and past. We were thrilled with all the information. Next time we will get a 4WD for the drive to... More

read desp4vacay information regarding the observatory it is very informative. My additional comments are:- the road across to the observatory has been resurfaced so it is in reasonable condition. Make sure you have trainers on your feet as the walk up the hill to see the sunset is not a smooth path - take a torch/flashlight to light your way... More

Be sure to have a full tank of gas before you head up to the observatory. There are no places to stop once you start up the mountain. We headed up around 5pm, and went to the observatory. They had a little gift shop there along with an informative video about the hiking and summit and some projects that their... More

As my son said. Its great to see so much money devoted to peaceful science! This is a great and literal window into another universe - in a beautifully rugged and remote place. The public viewing enclosure at the telescope is worth a look. The top of the mountain with its gleaming silver and white domes set against the reds... More

I Believe this is out of everything I have ever done, see on vacation. This is # 1. The space you are in, you feel you are touching the stars. To be that high up and not in airplain, is out of this world. You can touch the clouds, see snow in Hawaii and the darkest black that you would... More

If you can get up there and it's clear, and it's not snowing you are in for a treat! When I first went up there we felt like we were in a different world! The view is of the entire island and some of the other islands. Construction of multiple observatories is ongoing and they are spectacular .you should remember... More
