I have visited Haleakala only once. My aunt, uncle, some friends, and I arrived at the summit very early in the morning to watch the sun rise. It was CHILLY (really really really cold)!! The wind was blowing and both locals and tourists alike were all bundled up. If you go, bring warm clothes. The sunrise was beautiful. I even saw the green flash. After watching the sun rise, we had a great time hiking in the crater. You most likely will not need warm clothes if you go hiking. For more information on hiking in the crater, visit the Haleakala National Park Hiking Page. Haleakala is very unique. It is another one of my choices for the 7 wonders of Hawaii. (Check out my previous post if you missed the first 3 wonders)
I searched and searched for a great video which would show the sunrise at Haleakala. Many of the YouTube videos had an irritating wind sound throughout the sunrise. It is very windy at the top and these videos were not edited for sound. I did not think that would be too enjoyable. Others were pretty shakey video clips. Some were photo videos. After looking through six pages of videos, I finally settled on the videos below.
