Sliding Sands Trail, Halemau'u Trail, and Kaupo Trail are all fantastic ways to venture into and around the dormant volcano.  As you hike down into the crater, the gentle clouds create a dramatic backdrop to cinder cones and ancient lava flows painted in eye-catching shades and colors. Haleakala is indeed one of the most peaceful places in the world for quiet contemplation.  Though the scenery is breathtaking, don't forget your personal limits when hiking at this high altitude.
