The view at the top of the crater is beautiful!! Please, PLEASE be aware that this is not an easy hike. Even for people who are in good shape, the stairs are very steep. The distance seems much longer than it is, simply because each step is challenging. Be sure to bring water, sunglasses, and sunscreen, wear clothing you don't mind getting sweaty in, and for goodness sakes wear tennis shoes!
Being said, there are amazing 360 degree views at the top, and there is quite a sense of accomplishment once you get there! I went around 7:30 in the morning, and I'm so glad I did, as the temperature got much warmer as I was finishing the hike.
