Travel By Road between Oaxaca and Huatulco

"Highway 175, the cross-Sierra connection north with oaxaca, although paved, is narrow and winding, with fews services for the lonely 80-mile stretch between its junction with Hwy 200 at Pochutla and Miahuatlan in the Valley of Oaxaca. The road climbs to 7,000 feet into pineclad, winter-chilly Chatino and Zapotec country. Be prepared for emergencies. Allow eight hours northbound (to Oaxaca), seven hours southbound (from Oaxaca), for the entire 170 mile Huatulco-Oaxaca trip. "
