Mauna Kea Tour
It was great! She did a wonderful job narrating along the way sharing HI history. We didn't get to see the stars due to the weather but she didn't let it slow her down.
via Viator
One of a kind experience.
This tour was fantastic and the view even before sunset is unmatched. And that's not it, if you're the type to be interested it's amazing to see the change from sea level then through the clouds where visibility seems to be near 0 and finally up above the clouds with an unobstructed view all the way to the horizon. Our tour guide was a fountain of knowledge for not just of matters of the tour but also for the area and Hawaii in general. He was very kind and kept checking on our wellbeing for any altitude related ailments. All in all an excellent tour for the price.

The tour was paced well...
The tour was paced well with a stop at the visitor center to make sure that everyone adjusted the altitude. Warm jackets were provided on the top of the mountain.

Going to the observatories was great, guide could be more personable
Going to the top of Mauna Kea has long been on my bucket list. Went with this tour because it was relatively inexpensive and I didn't need dinner included. The guide, Andres, was very knowledgeable but could be a bit brusque, almost to the point of being rude. From reading the other reviews, it looks like Donna is the guide you'd want.

Starry Night, Mauna Kea Style
Mr. Arnott conducted a very organized and informative tour. The Mauna Kea summit experience was really fun and beautiful. I am so glad we accepted the offer to wear the freely-provided parkas; it was quite windy and cold at the summit, with freshly-fallen snow to add to the dramatic sights we saw ar sunset. The stars were beautiful and seemed so nearby that I imaged I could touch them.

Why this scores 71
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Mauna Kea Arnott's Adventures: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Hilo.
How much does Mauna Kea Arnott's Adventures cost?
+
Prices start at $255 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Hilo usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Mauna Kea Arnott's Adventures take?
+
Plan for about 7 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Hilo is not rushed.
Is Mauna Kea Arnott's Adventures worth it?
+
It holds an Outty Ranking of 71 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.8/5 across 156 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable culture & history in Hilo, and how flexible the cancellation terms are.
Can I cancel or reschedule Mauna Kea Arnott's Adventures?
+
No. This experience is sold on a non-refundable basis, so only book a date you are confident about. Similar experiences in the city do offer free cancellation if flexibility matters more than price.
Is Mauna Kea Arnott's Adventures suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 7-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Mauna Kea Arnott's Adventures?
+
Around 55 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Hilo can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Hilo and add a light layer if any part of the 7-hour experience runs outdoors or after sunset.
Where does Mauna Kea Arnott's Adventures start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Hilo within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Hilo?
+
On Outty we rank every Hilo experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Hawaii Volcanoes, Waterfalls, Beaches & Hilo Highlights Day Tour, Hilo Shore Excursion: Active Volcano, Lava Tube, Waterfall and Gardens, Hilo Shore Excursion: Volcano Safari Lava Caves & Black Sand. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Hilo?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Hilo?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
