San Andrés Zautla, Oaxaca
From Oaxaca City colectivos (MX$15), displaying Zautla on the front windows, depart frequently for San Andrés Zautla from the sitio on Trujano, west of Periférico Sur and north of the Abastos market. Tell the driver you're visiting the church and he'll drop off you off one block west of the church. Alternatively, buses leave frequently from the Central, the second-class bus station, north of the Abastos market. The church is visible from the bus stop. It is usually open in the afternoons.
To return to the city, head back to where the colectivo driver dropped you off and turn left. The colectivo and bus stand is two blocks away, straight ahead. If you took the bus, you know where to go. If a colectivo or bus isn't waiting there, be patient, one should be along soon.
