If you go to Mauna Kea, AND have a 4 wheel drive unit and lots of warm clothing you can drive to the top of the mountain--but you still can't see the telescopes. If you want to see how those pieces of technology work you need to drive to Waimea, and just off the city center there is an official... More

was excellent. We did not have a four wheel drive vehicle nor the time to visit the observatory on top of the volcano. But the Visitor Centre in Waimea, where the astronomers work on the data from the mountain top observatory was fascinating. A knowledgeable and helpful guide called Ed told us so much about the work done there. There... More

It's not Disneyland, it a real observatory, and deserves both more funding, and respect for what it is, a great experience that is volunteer based. It's worth the drive, as the views are amazing!

If you are interested in the telescopes this is a great stop. The visitor center isn't large but the lady at the desk took us around and explained the telescopes and other astronomical devices they are using. She was great with my 12 year old too. Asked him questions and got him thinking. She also gave us some take away... More

Takes a bit of effort to get to the top of the mountain, every afternoon the park rangers take folks with 4-wheel drive vehicles (only those are permitted to drive to the 14,000-foot summit of Mauna Kea) if the weather allows-up tot he top. Its a bit safer that way in a caravan as the roads are dirt and can... More

We were lucky enough to get a private tour of Keck #1's telescope. This is an incredible facility with extremely devoted scientists and support personnel. The trip to the almost 14,000 feet (4,300 meters) was very fast and with incredible scenery along the way. The 8+ meter telescope was nothing short of amazing! Although it is not easy to get...

The visitor center in Waimea is separate from the mountain top observatory tour. The Visitor Center is an embarrassment to such a prestigious enterprise. I was in and out in five minutes after reading every photo cation and staring at the static displays. Souvenirs were limited to coffee mugs, postcards, and a couple of t-shirts. Clearly some new direction and... More

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.
