Rocky Point is just over 4 hours by car from either Phoenix or Tucson. It is a free zone so no car permits or visas are needed. However, it is required by law that foreigners have Mexican insurance on their cars. This can be purchased at the AAA or in Ajo, Why, or Lukeville.
Mexican border guards conduct routine spot checks of vehicles. They are looking for expensive items like TVs or merchandise to be sold in Mexico plus large amounts of beer and alcohol. (Guns and/or ammunition are forbidden.)
On your return to the US, you will be stopped by US Customs and Immigration at the border who will ask all adults for their passports and to give the vehicle a security check. Children under the age of 16 do not need passports, but do sometimes need birth certificates for ID
From Phoenix: Take I-10 to the state route 85 exit (near Buckeye) and head South to Lukeville (at the border). Continue on 85 through Gila Bend, Ajo and Why (where State Route 86 intersects 85) on your way to Lukeville. You will be driving through the beautifully scenic Organ Pipe National Monument.
From Tucson: Take state route 86 on the West side of Tucson to Why, AZ and then go south to Lukeville through Organ Pipe National Monument on state route 85.
Continuing from Lukeville: Cross through the border and head South through Sonoyta. This is Mexican route 8, but is not marked.You will come to an intersection with another highway which goes East and West. (This is route 2 to Mexicali. Do not turn right.) Turn left at the stop sign and bear right after the bridge and go through town past the Vasquez store on route 8. There are signs pointing to Puerto Penasco (Rocky Point). It is 60 miles of good highway. You will be passing through the Pinacate Biopreserve.
In Rocky Point: Go through town to the municipal building at the 5th traffic light. Turn left (East) on the road to Caborca. There is a sign pointing to Las Conchas where we are. Go about 1 mile to the second Pemex gas station and turn right on the dirt road to Las Conchas. Pass the high school on the right and go through a guard gate for Las Conchas. Click here to view a map of the Las Conchas area. Go 3 miles to the place where the road takes a sharp right around 3 houses and then a gradual left. Our house is Lot 1 in Section 5 and is the 6th house on the right after an open space of 2 lots on the beach. We have a sign on the wall that says: Familia Libby. Welcome.
