We did the all day rainforest hike and had a great time. Our guide Jeremy was extremely knowledgeable about the rainforest, waterfalls, and Maui in general. During our drive on the Hana Highway he was able to speak to the flora and fauna, people, culture, food, etc. It was a great way to go on a non-traditional tour but learn everything you would on a bus site-seeing traditional activity. Lunch and plenty of snacks are provided. In terms of difficulty, the hike was moderately paced and Jeremy was conscience of varied abilities. I'm NOT a hiker and did just fine--my husband is an avid hiker and was able to go ahead and tackle other hills while the group chilled by a waterfall. Definitely worth the money!
