Directions to the Princesa Condominiums

From Tucson...

Take State Route 86 west from Tucson all the way to "Why", AZ.
Why is a good place to top off the fuel tank before crossing into Mexico. Gas in Mexico is available in most locations but the quality can be inconsistant and not what you are used to stateside. The stop at Why usually has about the best gas prices between Phoenix and the border.
Continue south on SR 85 through Organ Pipe National Monument to the border at Lukeville, AZ. Last stop prior to Mexico. The settlement at Lukeville is called “Gringo Pass” and has all facilities available if there was anything you forgot. There is a well stocked grocery store, etc. but the prices are pretty steep.
Crossing the border at Lukeville, AZ/Sonoita, Sonora, Mexico. you do not need a passport or visa since these towns are located in the Mexican “Free Zone”. You will need a passport or passport card to return to the United States.
Getting through Sonoita.... Once across the border you will continue south into Sonoita. The speed limit here is fairly slow so be careful. Driving in Mexico is not a problem as long as you drive defensively. About 2 miles from the border you will come to a three way intersection. Stay to the left (towards Caborca). Do not take the direction to San Luis. About 1 block south of there the road will split into a “Y”. “Pharmacia San Luis” will be on your right just before the “Y”. Stay to the right and you will be on the road to Rocky Point. You will pass “Vasquez’s” on your left if you have made the correct turn. There is a traffic light soon after “Vasquez’s” that is easy to miss if you don’t know it is there. Continue along the same road all the way to Rocky Point. “Vasquez’s” and the “Pharmacia San Luis” are good places to stop and visit. The pharmacy carries many items over the counter that require prescriptions in the US. “Vasquez’s” has a great selection of all kinds of Mexican curios, pottery, liquors and everything else. You will not be able to haggle prices at these places but may find just what you are looking for.
Sonoita to Puerto Peñasco. The highway from Sonoita to Puerto Peñasco is approximately 50 miles of open range. Being open range you are subject to encountering livestock on the highway on occasion. You will know you are close to Rocky point when you start seeing sand dunes.

From Yuma...

From Yuma there are two main routes available to the Mexican border town of Sonoita where you pick up Mexico Route 8 (MR-8) to Rocky Point. There is an American route and a Mexico route.

Mexico Route

To take the Mexico route from Yuma proceed south on Arizona SR-95 to the town of San Luis. This is a U.S. border town across from the Mexican town of San Luis Rio Colorado. In San Luis Rio Colorado you pick up Mexico Route 2 (MR-2) and follow that to Sonoita. In Sonoita you pick up MR-8 to Rocky Point (Puerto Penasco).
The author has never been over Mexico Route 2. The route was suggested by a visitor from the San Diego area. Being adventurous souls they took the MR2 route on their trip to Rocky Point and were kind enough to share with us their experience.
