GPS Coordinates to the entrance to the Road to San Pedro Martir:
From Ensenada: Take Mexican Highway 1 south, at km 243 Ensenada until you come to the small village of San Telmo. Turn left when you get to the signs for the Observatorio Astronomico Nacionale and the Parque Nacionale Sierra San Pedro Martir. Drive 50 km east on a paved road until you get to the Rancho Meling entrance – along the roadway there are several signs similar to the one below.
NOTE: It’s very important that you gas up at the PEMEX Station in San Telmo before you start driving up to Rancho Meling – it’s also a good place to stop for a cold drink and use the restrooms.
