Fabulous tour and well worth the time! David was a wealth of information regarding the history, geological formations, flora & fauna, customs, environmental impacts, etc. of the island. We even got a mini language lesson which really helped me during my stay! I loved learning about the culture and all the many settlers that have made Hawaii the diverse place it is today. It is a long day, but I knew I would never get the indepth view of island without a tour. I am so happy I picked Wasabi. They provided rain jackets, lunch comfortable ride, plenty of water/snacks and great customer service. We saw amazing sites, Honu, goats, sheep, birds, and enjoyed a local cofee plantation and Hawaiian bakery.
