Seeing the Black sand and the turtles. And seeing the shoreline in the volcanic landscape. See the difference between the two sides of the island.

Very informative and fun. David Human - our tour guide - was exceptional. Apart from being very professional and courteous, he knew the Big Island very well and took us to spots that were 'unthinkably brilliant'. Very punctual - picked us up from the hotel on the dot of time and dropped us off at the hotel. David was very sensitive of the diverse needs of all the tour participants. Overall, a day with David on this tour has been fantastic. I encourage everyone who is visiting Big Islands to try this guided tour. You will not be disappointed.

Excellent and informative tour. Interesting itinerary with great stops at the national park. Tour guide Dave was very personable and knew so many facts. Highly recommend.

Our guide, David Human, was exceptional. Very knowledgable and a great story teller! He made everything very interesting for us.

We had the pleasure of taking a tour today to Hawaii Volcano National Park with Zane Smith, owner and operator of Hawaii Geo tours. We have been to the park many times, as we are frequent visitors of the Big Island, but never on a guided tour and I must say, being with Zane was the MOST WONDERFUL way to visit the park!! We rode in a luxury van, with only 12 participants. Zane was absolutely the best person to be with for this adventure. He was engaging, funny, inclusive and so full of information. The day was very long and included stops that we had not seen previously, including walking in a lava field and going to where the park meets the ocean. He made everyone feel welcome from the start as he shared his expertise as a geologist with the group. Thanks, Zane, for a fantastic tour and thanks for generously sharing your wonderful photos with the group I HIGHLY recommend Hawaii Geo tours for your visit to Volcano National Park. You won't be sorry!!!

An incredible tour with our geologist guide, Zane. We’ve been to the Volcanoes National Park before, but Zane and Eric gave us more insight into the history, geology and culture of the Big Island.

We ere a group of 4, so very enjoyable. David was knowledgeable and knew to entertain us. Lunch is provided, snacks and drinks are available throughout the day. Will do again next time!

Looking down into the volcano charter. Dave was an absolutely superb guide who made the whole day come alive.

It was a wonderful tour. David, our tour operator, was extremely knowledgable, and knew exactly what information would be the most interesting and fascinating for us. Within 11 hours, we covered most of the big island, and it never felt exhausting. Additonally, David created a lovely atmosphere in the group, where we got along really well, and ended up going for other activities too with people we met in this group. I will highly recommend this tour, especially if you are visiting the big island for the first time.

Don't think twice, book this tour! David was amazing and very knowledgeable about the island. It’s an incredible experience and would definitely do it again if given the chance. It’s a long day but there’s so much to see and experience.

David was an excellent guide to our trip to the Hawaii Volcano National Park. He was extremely knowledgeable about everything to do with lava, rocks and how the area formed. I highly recommend this small group tour.

Zane was an amazing tour guide! He is so intelligent and knowledgeable about the island. After visiting the National park he stopped on Satellite Rd since it was a new moon and we got to experience the most incredible night sky! This was probably the best experience on the Big Island! I highly recommend!

One of the best tours I have ever taken. Our guide, Dave, was awesome. Extremely professional and knowledgeable across many subjects. We saw so many different things on the tour and Dave’s narration really added to experience. Would recommend as a must do. Be prepared for a long but worthwhile full day.

Went on tour Dec 3rd, cannot remember the three tour guides an drivers. Tour was fantastic and guides were great in all phases, demeanor, knowledge and driving. Thanks

It's hard to pick the most memorable part of our tour because it was a day filled with extraordinary sites and experiences. Overall, it was our Tour Guide Dave who really made our 11 hours especially fun and informative. Dave really knows the island, the history, the people, the sites, etc. We feel so lucky that Dave was our guide that day. We truly will never forget the tour or him!

David was a fabulous tour guide! He was SO knowledgeable, had a great sense of humor and was so polite and kind. We learned so much from him-plant and animal life, types of lava and their flow and geological history of the island. I would highly recommend this adventure! We also had a great lunch and very nice couples and singles to travel with- friendly and kind. (We just wish we could have had water in the van- we all followed the rules.)

The adventure was amazing! Saw so many wonderful things like lava tube, volcano crater, black sand beach, turtles and so much more! David our tour guide was so knowledgeable and had lots of stories to share. I’d recommend this excursion to anyone.

Our guide, David, was amazing. So friendly and interactive with everyone on the tour. He was very knowledgeable about the volcanos, mountains, wildlife and Hawaii in general. I learned a lot while having a great time. We saw a lot of sites and we had plenty of time at each one. Totally recommend this tour….especially with David.

Absolutely fabulous tour! Zane was so knowledgeable, fun and just such a great teacher. I highly recommend Zane for the best tour experience.

An incredible day packed with lots of stops all over the island. Amazing views and the tour guide was so knowledgeable about the island and it’s history.
