First Time in Hawaii - This is our first time in Waikoloa and I have to say that this is the best tour I’ve ever experienced. You have a great guide by the name of David Human, who does a great job of narrating as he drove us from one end of big island to the other. From the coffee farms, the volcanoes, and rainbow falls. I give this tour a 10 out of 10 and is a must for all who travel to Waikoloa.

Fantastic Trip! - David gave us an amazing day around Big Island. He was so informative and went out of his way to make sure we had a memorable experience. We loved the turtles at the Black Sand Beach. Having lunch on the rim of a volcano was really cool and the food was great! I highly recommend this tour. It’s a great way to to see a large part of the island and experience all the climates in one day.

Adventure Packed Day - Every adventure was perfect. Pickup was on time, van very comfortable & David’s descriptions & historical connections to each stop added to the day. My favorite was Volcano National Park views & lunch at crater’s edge. Also walking through the lava tube was awesome! Wear comfortable walking shoes for variable terrain. Distances are short - moderate in length. Overall, best part was David & that he drove so I could enjoy myself!! Yes, I recommend this tour!

Memorable tour - This tour was wonderful, well worth the money spent. We visited most of the highlights of the island in a small amicable group of 7. The most memorable was the view of the Kilauea caldera in the Volcano National park and the lava tube. Our guide, David, was very knowledgeable and friendly. He made several stops to point out some highlights along the way and made sure we were all comfortable. Thank you!

Wonderful tour - we saw so many beautiful places! - We had a great time on this tour! David was our tour guide and he was awesome! It is a long day (nearly 11 hours), but great fun and you will get to see so much of the island. You won't want the day to end! Sit back and enjoy the beautiful views as you go from place to place. We went to a coffee farm, Punalu'u Black Sand Beach, Volcanoes National Park (saw Kilauea, went down Chain of Craters Road to the lava cliffs, walked through Nahuku Lava Tube), Big Island Candies, Rainbow Falls, and back to Waikoloa via Saddle Road. Our lunch was at Volcano House and we got to choose what we wanted for lunch. There are restroom breaks along the way. David kept us entertained with stories and made everyone feel welcome. The van is very comfortable. I'm so glad I chose this tour - it was a fantastic day!

Nice day trip - Chances of seeing " active "lava flows are extremely low, but they can't control that . There is walking on uneven surfaces , so take note if you are unsteady in your feet. Nice to be picked up from hotel and not have to worry about going to a random pickup spot in a town I've never been to . Dave was an enthusiastic and great guide.

Spend your money elsewhere. - The views from inside Volcanoes National Park are the ONLY reason this tour got 2 stars. Our tour guide, Zane, talked about millionaires and billionaires and how much everything cost for the majority of the first hour. He loved mentioning his girlfriend, who he knows on the island, how much things cost inside the van and pointing out where wealthy people live and go on the island. My family booked this tour because we wanted to learn about Big Island. I will admit, this was my mistake, because we weren’t interested in a geological tour. We wanted to learn about big island culture and history. However, all that being said.. My parents could not hear much from the back of the bus, and after we asked Zane the first time.. he checked in with us to see if we could hear better. We could for a little while, but after about 20-30 minutes we couldn’t hear very well. We asked him 3 more times during the course of the day to speak louder or adjust the mic and there was no difference and he never checked in with us again. Things got a little better once we were in Volcanoes National Park. He spoke more about the history of the volcanoes, how they were formed, the different types of lava flow and the craters. But as I said before, my parents couldn’t hear much from the back. So when my mom asked a question about the differences in lava and why they looked different, she was met with a snarky attitude of “well don’t you remember the video?” Which wasn’t the last time during the day that we were met with snarky behavior or an attempt to be funny that just missed the mark. Not long after that, my mom slipped on some loose rocks out on the lava formations where he took us. The fall wasn’t bad, and she bruises easily so it looks worse than it is. But instead of being met with concern by our tour guide, like anyone would expect, Zane told her in a sarcastic tone that she couldn’t walk back by herself. He didn’t check in with her until after he got back to the van, a bit later. A very nice woman on our tour helped escort her back until I could reach her. Once Zane made it the van, one of the first things he said was “oh that’s not bad,” as I’m trying to clean up blood from where she fell. Luckily the woman who helped my mom back had bandaids, because Zane and Hawaii Geo Tours have no sort of first aid. He said they had to stop during Covid, but we’re past that now. Carry bandaids (even if you can’t administer first aid), just do better and be prepared. The rest of the tour had some pretty and cool views. We walked through a lava tube, stopped in Hilo for a farmers market and to see Banyan trees. Overall, I would skip this tour, save your money and a headache from hearing a bunch of “I did this, my girlfriend does that and this cost $xxxxx.” There were also a couple points in the tour where it felt like he was digging on the Hawaiian people. And after having an amazing tour in Maui with someone who’s connected to Hawaiian culture, I felt offended on behalf of the Hawaiian people with the way he spoke a few times.
