We were told hundreds of people trek up each morning to view sunrise atop the crater rim. If you do, dress warm and prepare for traffic. We visited around 11am as part of our bike ride down the mountain. At that time it was warm enough for shorts and t-shirts. It's a pretty easy van ride up the mountain. We were told that riding bikes down as part of the sunrise tour can get a little hairy as there is a great deal of traffic coming off the mountain in the morning.
The views are great and the bike guides provided plenty of information about the crater and the interesting US observatory and "star wars" facility atop the crater. They also told us about the protected silverswords plant and program to replenish the plant around the crater.
I recommend you take the time to see the crater no mater what time of day. It's amazing. It's best described as the surface of Mars. It's a real natural gem on Maui.
