When you are visiting the volcano, definitely make sure to bring water and good hiking shoes. There are a lot of hiking opportunities around to get to the good views, both moderate and easy. From the parking lot beside the volcano, there are some steps that are a fairly easy climb if you're in any kind of shape, from which there is a great view. There is also a hiking path leading up to some other views, but this is a more strenuous ascent and in the hot climate, water is a must. Also make sure to bring sun screen and avoid visiting between 11AM-2PM, when the sun is unrelenting.
