For everybody traveling in June to Guadalajara or surrounding area come and visit Tlaquepaque.
Every year they celebrate San Pedro with all kinds of activities during the whole month of June. Tlaquepaque is a part of Guadalajara and you can take a bus from the center of GDL (Bus 275, 647, TUR) that takes you directly to the center of TLQ or take a taxi that will cost you around 70 pesos.
