We are looking to book a Waipio Valley ATV tour. We are staying in Waikola area and going to drive over. Read reviews for around the rim and Big Island ATV tour- Waipio Valley. The second one comes up as the first tour on the trip advisor page for Waipio Valley. But I can't seem to find who is the actual tour provider for the second tour. You can only book through trip advisor or viator. I prefer to book direct. The reviews and itinerary for the trip advisor tour were preferable for our preferences but I wanted to know if anyone had any experience with either?
