Here is a nice GoPro camera shot video of the Haleakala Skyline trail part 1.
Youtube user 253MTB has a lot of great action videos and this one shows the trail from the start at the Visitors center on Haleakala’s summit. If you go on this trail be warned… lava rock cinder hurts when you fall into it. I rode this trail in the 90′s… all the way to Makena actually. And took a spill close to the beginning. Bikes weren’t as hi-tech then but you can fall on any bike if you go to fast. I had a nice triangle scar where I used my arm to block my face from the cinder. If your careful, you’ll fare much better than I did.
After the cinder, you end up in Poli Poli forest, where a gorgeous set of trails run through the deep woods. After that you end up in Keokea Maui so stop at Grandmas Coffee for a treat!
