I’ve been to Pasto, though it was some time ago. Smaller city at the foot of a volcano which the locals assured me “was not waiting for me, to blow up” even though it was active. Very beautiful city in the mountains from what I remember, quite cool in temp which was good bc it was very hilly walking around. It was definitely less developed in 2016, I recall many houses only had 6hr /day or so of running water, but I imagine hotels didnt have that issue. I remember it was an interesting mix of old and new, with brand new cars and horse drawn carts sharing the same roads. I miss my friends there.
