We went on the Sunrise Tour. We were picked up at our hotel at 2am. The van proceeded to their home base, where we had a choice of bagel and muffins and were given windgear. Then we took a van to the top of Mount Haleakala, where our tour guide took us to the top of the crater to see the sunrise. 10,000 feet above see level can get a bit cold (40 degrees) and windy, so definitely dress accordingly. After the beautiful sunrise, we retrieved our bikes and were given a quick tutorial. Basically, you just glide down winding roads, at midpoint you stop for picture-taking, and at the bottom of the volcano you have breakfast at a small restaurant. After breakfast, you follow your tour guide to a small church where you can take pictures and conclude your tour. The bus takes everyone back to their hotels and/or resorts. The overall experience will stay with us forever - how often do you get to glide down a volcano? The tour guides were friendly and helpful. They never hesitated to take a picture for you. For those who do not want the sunrise tour, you can do an afternoon tour. Hopefully this will be of help to you.
