its all about location and you will shoot there,
Before leaving anywhere I study the city,area,place,location as much as I can to figure out what I will do there. A lot has to do with shooting preferences and many other personal points....
Tripod / Flash / triggers and other accessories are given
+1, I usually do tones of research before deciding on gear, but it's hard for me to leave without a D600 kit so everything else are usually build around it.
Tripod is a given even IF I decided to leave my DSLR at home . Flash and triggers are not so much for me, I usually wouldn't bring them for backpacking.
