When driving to Puerto Peñasco from spots west, some travelers opt to stay on I-8 to Gila Bend, AZ and then south to the traditional Lukeville/Sonoyta border crossing. Another option is to cross into Mexico via Mexicali/Calexico or the San Luis port of entry and take the “Coastal Highway” to Puerto Peñasco. NOTE: Spring 2024 – periodic roadwork projects in spots along coastal route
San Luis Port of Entry: After crossing the San Luis Port of Entry, remain on MEX-2 east toward Sonoyta, exiting shortly outside of San Luis Rio Colorado at the sign toward El Golfo. This leads to the “Coastal Highway” connecting El Golfo to Puerto Peñasco and includes a short toll-road (approximately 110 pesos). Please note: The Coastal Highway may present drifting sand and spots of rough road conditions due to erosion. As a second option, if driving to Sonoyta, continue on MEX-2 and then take MEX-8 south to Puerto Peñasco.
