Pick the places you want to see and the things you want to do - there should be something that draws you to a particular location. It seems you enjoy hiking, so that is one activity you can concentrate on. If there is some other interest or interests that could be fulfilled by the places you've mentioned, then you've made the right decision. But if you are going to certain places and aren't clear as to why, then you need to make an adjustment. Either have a reason (and "just because" is as good a reason as any) or alter your plans.
