Medellín spreads across the Aburrá Valley with the Metrocable cable cars climbing barrios formerly off-limits, Comuna 13's transformed graffiti district, and Guatapé's painted village with El Peñol monolith two hours east.
Drier season (Medellín runs eternal-spring around 22°C), Feria de las Flores in early August aside, and the city's terrazas full along Provenza and Parque Lleras.
Feria de las Flores ten days of August fills Medellín with flower carriage parades (silleteros), antique-car parade, and Orchestra Festival the city's defining event.
First wet season brings afternoon storms but the mountain valley stays around 22°C year-round, and the Comuna 13 walking tours reliable.
Second wet season with afternoon storms, Festival Internacional de Tango late June aside, and the Christmas lights of Medellín (Alumbrados Navideños) along the river from December.
