Sierra Madre del Sur Pacific Descent - MEX 131
A fierce and mesmerizing mountain run traversing the wild Sierra Madre del Sur from the central valley of Oaxaca down to the legendary Pacific surf breaks of Puerto Escondido. Weaves through Zimatlán, Sola de Vega, and San Gabriel Mixtepec, plunging through distinct microclimates from arid agave fields to misty cloud forests, coffee fincas, and coastal jungle. Road Quality: Highly technical, narrow two-lane asphalt punctuated by sharp topes, sudden landslides with packed dirt detours, and occasional cattle around blind turns. Safety & Military Checkpoints: Community security checkpoints and municipal police stops; strictly daylight riding only; during the rainy season (June to October), flash slides can temporarily block sections; exercise patience. Fuel Range: Pemex in Oaxaca City, Zimatlán, Sola de Vega, and Puerto Escondido; top off in Sola de Vega to easily bridge the 65-mile remote mountain stretch.
