The original Medellín free walking tour, and still the one that fills first. Three hours through the centre — Botero's fat bronzes, the Plaza de las Luces, the parts of downtown most visitors are told to avoid — on a pay-what-you-want basis.
Their separate Escobar tour is called More Than Escobar, which tells you the argument: Medellín is tired of being a crime-tourism destination and this is the version that puts the man in proportion. They also run a Comuna 4 barrio tour, away from the Comuna 13 crowds.
There is no phone number and no WhatsApp. Every seat is booked through their own site, and the popular departures go days ahead.
