My friend and I thoroughly enjoyed this tour. Our guide Steven was very personable and knowledgeable about Maui/Hawaii and was happy to answer everyone's questions. The views are beautiful and we loved learning more about the history and significance of the place (plus, I wasn't about to get up at 2 am for a sunrise tour). They provide backpacks and jackets, which is very convenient. My only slight criticism is how much they stressed the difficulty of the hikes, which almost made me cancel. If you are reasonably fit and walk a lot (or even hike regularly), you will be fine. The terrain is not very difficult (but it was dry when we were there). Decent running shoes are fine. The "difficult" aspect is, that you start the hikes by walking down and then, naturally, the way back is all uphill. However, we weren't rushed and people could choose their own pace.

This was great tour. Did two longer hikes had lunch then a shorter hike. Our guide was very knowledgeable about Haleakala. One thing to keep in mind: not all of us visitors are accustomed to the high altitude, and while we did not get sick, a few more short breaks would have been appreciated!
