It's worth every bump you hit! In our last visit we were…read moreunaware we needed four wheel drive and didn't attempt with 2 wheel. This time we made sure to take 4 wheel drive up to the observatory. Please bring warm clothes including earmuffs and mitts. You will be thankful to yourself for getting it. It may be cloudy when you drive up with ring of clouds around both Mauna Kea and Mauna Loa but many a times sky above at 13k is clear. You would also see Haleakala in west in distance if its clear. - BONUS! At 9k visitor center there is a restroom and then there are porta potties where observatories are. The road is 25% grade so be kind to your breaks and use 4L with m2 to drive up and 4L +drive while coming down. The rangers checked tank plus if the car is 4wheel and have instructions. Mind you! They also checked break after we reached down. That's good for you and your car! Now up at the summit you might be lucky to see the observatories rotating and opening for their nightly duties. They used to allow admissions in the past and sky gazing program at visitor center but not anymore. So you might have to check with them. No drones allowed - fyi! The rangers will also be everywhere and make everyone leave 10 minutes after sunset. Key point- bring enough water for all the members with you. Water has oxygen which helps you breathe and keeps you hydrated. Coming back to experience... The views are ethereal. This was one of the topmost points in my list ( pun intended) in big island. Sunset hues are out of the world. If you go on moonless nights and clear days you might get to see more stars and planets.

Being in Hawaii on the tallest mountain in frigid conditions is not what I want in a Hawaiian vacation. You have been warned, come prepared. It was pretty but if you're not prepared you will not like it. Bring snow pants and a parka with thick gloves. I could have skipped this excursion entirely but my husband wanted to go and he can wear shorts in a blizzard. The drive up and drive down is tedious. I had no idea that this would take 5 to 6 hours. You can only go up in all wheel drive or four wheel drive. If your brakes are too hot on the way down you have to pull over at the visitors center and wait over 30 minutes to leave. It was one of the worst times I've had on vacation. I may have a bad attitude but people should know the reality of it. I'm a big fan of looking at pictures of this place rather than actually going.

Catching sundown on the way up was absolutely beautiful. Some conversations heard inside: "You can pay someone $20 per person to go up, up to $200. But you get what you pay for, and the more expensive ones will drive, clothe, and feed you, and it's totally worth the price." Chilling at the visitor center - the staff was crazy knowledgeable about the stars, the area, their books - and made great recommendations (and prevented me from buying the wrong star chart for the wrong location and the wrong language!) - so be sure to ask them questions if you have them! Managed to catch some constellation discussion outside (he used a green laser pointer which made it easy to follow along!) But for the love of Superman - please don't turn in your BRIGHT LED LIGHTS at night when people are trying to enjoy the darkness and look up. They have red light flashlights there, or maybe let your eyes adjust and go slow - there's no reason to run!

Oh well, have a great day and keep on Yelping Oh darn, it won't let me post unless it's longer. Hmmmm, I used the app Waze to find my Sons Workplace and it was right on point. The landscaping is beautiful and simple. As I texted him that I was in front. There he was. Ready to go and so off we went. But before leaving he noticed that I had a sensor light on for my tire and told me where to drive and he went ahead and brought me to something like a mechanic shop on the premises to blow up my tire and guess what! The light went off lol and off we went. What? All I had to do was give it some stars and now it'll let me post my review. Au-we! Lol

Look - you won't be visiting this place unless you are a professional astronomer. But if that's…read moreyou, and you do visit, it's about as nice of an astronomical facility that you'll find. Lots of parking - visitor parking is just outside the front door. Facilities are large, and very, very quiet. Remote (Subaru) observing capability, and lots and lots of outstanding support. Washrooms have a bidet - a nice "touch". 'Imiloa is a 2 min walk down the hill, with a great cafe and gift shop (7am - 4pm + dinner Thurs-Sun) and wonderful overall facility.

Tip2: Need an all-wheel drive vehicle to go up to the Mauna Kea summit beyond this point. If don't have all-wheel drive vehicle, one can hike up the Sunset Hill to watch sunset and/or stargaze.
