How about a volcano you can climb in under an hour. This popular hike has a nice trail up the side of the mountain, then an easy rim walk around the entire crater rim. Views are nice in all directions and you can check off another volcano summit under your belt. I easily did this hike while my wife was at the nearby thermal hot springs.

The one and only plant I saw on the entire crater rim was hiding under a boulder for protection.
