"Alley of the Frogs" is among the top things to do for Puebla on TripAdvisor but we had a hard time finding it because there is no street actually called "Calle de Los Sapos". We eventually found a flea market on Calle 6 Sur and realized this was the "Alley of the Frogs". The segment of the street right passed the flea market is one of the prettiest streets we have seen in Puebla.
