We did the Mountain Safari Adventure. We had a great guide, and did a terrific tour to Waimea Canyon and on land that few people get to see. It was terrific, but it was too long. Worse, it was seven hours in a 4 x 4 van over roads just barely passable. Imagine being tied up and put in a duffel bag and beaten with a ball bat. That’s how we felt after the tour! But I would not have passed it up for anything. We saw so much, and learned a great deal about the island. Our guide was wonderful, and I recommend this tour for the young and those without back problems. For anyone over 40, be careful.  Waimea Canyon is wonderful. Interested in becoming a travel agent?
