Medellin is a beautiful city located in the Antioquia region of Colombia. It is the only city in Colombia with a metro system (train & cablecars and we rode both today)! For us it was a day of firsts. We set out to visit Park Arvi. Park Arvi can only be reached through Medellin’s cable car system, which is connected to their metro system…which is connected to one of the poorest neighborhoods in Medellin. It was an interesting ride.
