I took the bus from México City to Oaxaca on 11 February 2019, a beautiful trip through forests, mountains, and deserts. Not far from México City there are views of the volcanoes Iztacchuatl and Popocatepetl.
Oaxaca is wonderful. Locals and visitors stroll the pedestrian only streets near the Zócalo in the evenings, watching street performers, looking at artisanal goods in street stalls, and eating in the cafes and restaurants. There is live music every night in the Zócalo near the cathedral.
