The track below shows two routes linking Oaxaca and the charming hill town of San Agustin Etla. The outbound route, which uses the unfinished highway of the Libramiento Norte and a patchwork of back roads, is certainly the more scenic and charming – as well as the more difficult option. The return to Oaxaca, by contrast, follows main roads which are much more crowded and less attractive, but have the virtue of being much more level. The rider is certainly entitled to ride the loop in either direction, or to choose either leg as an out-and-back ride. Any way you slice it, this is a significant urban ride, amounting to 31+ miles (45+ km).
