Guess where we've been

Well, we came back last night, from an adventurous vacation. It actually was not going to be too adventurous, but I got the "nosebleed from hell," and we were waylaid for two days, as I gradually got my strength back after losing a liter of blood, and discovering the available medical care in rural Canada.
Anyway, we're happy to be back.
See if you can guess the location of these photographs - some of the hints I dropped before taking off can get you there.
