Had an absolute amazing time doing the Kohala/Hamakua coast helicopter tour with Sunshine Helicopters.
We were lucky to book it at all, since they were full during the dates we were free. Luckily they were able to put us on a waitlist and contacted us about an opening. I was so eager that I called in to reserve the spots while my flight to Hawaii was about to take off! A+ for communication.
The flight itself was great too. After a brief safety instruction, we were taken to the helicopter, got our photo taken (printed version available for purchase for $15 USD), and were seated based on our weight.
Don't fret, because there is no bad seat in the helicopter! I sat in the back middle seat and I was able to see everything the pilot pointed out. Not only that, but he flew in a way so that one side saw the landmarks, and then turned around so that the other side could see it.
We were lucky to catch some whales during our flight, and he spent a good 3 minutes circling over them so everyone could get some great views!
Plus the flight path itself was great! We flew up the coast and then through a valley to cut across the Big Island itself. Tons of waterfalls that you wouldn't be able to see otherwise. Also gave another perspective on locations that we hiked before, such as Pololu Valley and Waipio Valley.
I'd recommend everyone to take this tour! Sunshine is definitely one of the more affordable options, and it was definitely worth the price!
Only nitpick is that I wish digital copies of our photo were provided when we purchased them. They said a digital copy would be on the USB drive if we purchased the video recording of our flight, but I personally didn't find that one worth the price.
