Once in a lifetime experience - Amazing experience. The top of Mauna Kea feels like you’re on Mars and the night sky is dazzling. Our guide Donna was awesome (get her to take your picture —... read more the woman should have been a photographer!). A must-do if you’re on the Big Island.

  Best tour for Mona Kea  - Andres was the best guide ever! He was flexible with our family needs and got to know us personally. Take the offer of the jackets and bring hats... read more and gloves!! We made stops along the way to the top that Andres showed us all the key sights and helped us acclimate to the elevation. He had so much interesting information about the environment, local culture, and the observatories that he shared. He made sure we had plenty of time at the top and had a great stargazing session after. Highly recommend!

  Best horseback riding trip ever!  - Amazing guide and very long tour. Definitely got our money's worth with this excursion. Many memories made today!!! Do this with Margo you won't regret it!

  Amazing Mauna Kea Tour!!! Thank you to Guide Donna  - We just got back from our trip of a lifetime to visit Hawaii as a couple - long delayed honeymoon by many years A dream was to see the... read more observatories and so glad we found Arnott's Lodge & Hiking Adventure. I had lots of questions, plus we wanted to try a day tour which is less common and everyone who answered phone was super nice & patient with my many questions. We ended up being the only couple on the tour with a fabulous guide Donna who knew so much and gave us a great tour for hours. We started by visiting the rainbow falls - cloudy - drizzly - didn't matter - still gorgeous. Note: If blue skies are important to you, the weather in Hilo area unpredictable and often cloudy/rainy so plan accordingly . Then up Mauna Kea - broke through clouds & drizzle to blue skies - like being on another planet. We stopped at the different telescopes - yes, after reading & watching 3 Body Problem had to pose in front of the giant radio telescope. Donna was amazing not only gave tour but took lots of pictures of us and pointed out areas of interest and local recent history. Keck visitor gallery -small hall with photos - an actual bathroom (!!!) and glass wall for viewing telescope is open again limited hours. At first we were debating this due to cost but so glad we splurged and had the experience of a lifetime we will always treasure. Views stunning beyond belief. Donna, was a a rockstar tourguide and driver. Thank you Donna for your time & expertise & hospitality!!!
