This is a once in a lifetime experience. When do you get to watch the sunrise from the top of a Hawaiian volcano? Go early in your trip when you are still jet lagged. It will make the 2am pick up at your hotel much easier. Dress warmly, it is VERY cold at the top of the volcano. If it is clear you can see other islands in the distance. Once the sun is up the tours start down the mountain. It is a long ride down, but it is very easy. You only go as fast as the slowest person and there is very little actual pedaling involved. You end up at a gorgeous beach and back to your hotel in time for lunch and a nap in the sun. A great way to see Maui.
