Getting there & away
Many of the Valles Centrales’ most interesting places are visited by daily tours run by Oaxaca travel agencies.
There’s also plenty of public transportation. An alternative to traveling by bus, costing about twice as much (but still cheap!), is to take a colectivo (shared) taxi. These run to places north of Oaxaca in the Valle de Etla from Trujano on the north side of the 2nd-class bus station; and to places east and south, in the Valles de Tlacolula and Zimatlán, from Prolongación Victoria just southeast of the Central de Abastos market.
They leave when they’re full (five or six people).
