This was a free trip for us, arranged through our timeshare. We had a great time. Larry was terrific, very accommodating and super knowledgeable. He shared Hawaiian myths, history, and was familiar with most of the plants along the way--I never knew there were so many types of gingers and that even the non-edible gingers had their uses. The highpoint for me was seeing the sea turtles on the "blue roof beach" and the black sand beach and lava tube. We had expected to drive the road ourselves and it was so much more relaxing to have someone else drive so we could enjoy the scenery. Larry's expertise enriched the entire day. If you can afford this, I highly recommend it. And it was a full day!
