We booked this trip the day after we landed in Hawaii. I consider ourselves lucky because they were booked out about a week and a half and we had a party of 6. Trip advisor said that there was no availability for that many people so we tried through the actual website and we got the last 6 spots for a Saturday tour.
It was amazing and our tour guide Zachary was exceptional. He knew his stuff. No matter what questions were thrown at him he had the answered. Very knowledgeable about the island, plants, trees, geography, volcanoes, everything. Very personable as well and funny. The guy even sat in the sand with my 10 year old to explain how some of the volcanic hills were formed on the island. He always kept us on schedule so we had enough time for an extra stop or 2. No shortage of food, snacks, drinks or anything like that. Can’t say enough good things about the tour.
