While I'm not familiar with this particular tour, I am familiar with Kauai, and there's not too many places they can take you on land. Didn't they give you a description before you booked, or did you not have that option? Jeep to me would be land, but they do have many helicopters to see the canyon or the North Shore. Not that brave to get on them. There are also various types of boat trips you might take. When they refer to a Jeep Safari, the first thing that comes to my mind is Waimea Canyon. This was our 3rd time on Kauai, and our 3rd time seeing it. Bring lots of film, video camera, and binoculars (We didn't have, but a gentleman had a telescope and letting everyone use it). Many mountain goats, and to me, the most gorgeous site in the world. There's only a road than goes around the island, and heading to the North Shore, you have narrow roads, with 13 1-way bridges, and no guard rails. You would pass Princeville, where Matt LeBlanc just got married. Beautiful, but can be hairy at points. Going the other way towards Waimea Canyon, the road is curvey, with a couple of areas that are like roller coasters. Take some motion sickness pills, close your eyes, and let them drive for you, as it's a sight you'll never forget. The road doesn't go that much beyond the canyon turnoff. There's a military base, and a desolete beach, then the cliffs that you hit if you take it going North. Bring water with you, because when you climb, you dehydrate fast. We're going away, and will be back Sunday if I can answer anymore questions for you about Hawaii. We've been on the 4 main islands at 1 time or another, and this was our 4th trip, so might be able to help you. Have fun, and be sure to take a high number sunscreen, as the sun is very instense, not what you are used to in the 48.
