Sierra de Miahuatlán & San José del Pacífico - MEX 175 South
Acclaimed by global adventure riders as one of the single greatest motorcycle twisty corridors on the planet. Plunges nearly 10,000 vertical feet from the high alpine pine and cloud forests of San José del Pacífico (famed for mountain cabins and magic mushrooms at 9,800 ft) straight down to the tropical Pacific bays of Huatulco and Puerto Ángel. Features nearly 2,000 continuous, rhythmically banked curves carved into lush emerald mountainsides. Road Quality: Paved two-lane asphalt throughout, though tropical rainstorms frequently bring mossy corners, fallen eucalyptus debris, and sudden potholes. Safety & Military Checkpoints: Thick, disorienting fog is routine in the afternoon around San José del Pacífico (reduce speed and track centerline); military checkpoint near Miahuatlán and naval checkpoint near Huatulco; ride strictly during daylight. Fuel Range: Pemex stations in Oaxaca City, Miahuatlán de Porfirio Díaz, San José del Pacífico, Pochutla, and Huatulco; fill up in Miahuatlán before starting the alpine ascent.
