[/h][h=6]Taking the coastal highway route (description from Nov 2011 JoinUs):
If crossing the border in Mexicali, there is a short toll road (12 pesos – about $1 US) to San Luis Rio Colorado. On the East side of San Luis Rio Colorado, as you go along Mexico Highway 2 signs begin to point to the Golfo de Santa Clara, which then leads to the Coastal Highway. The toll road down from San Luis RC to just north of Santa Clara was 94 pesos (about $7 US) the day we did this in August (2011), but is well worth the time saved and prevents hitting numerous speed bumps along the free road. Just past the toll booth (or before when heading North) there is sometimes a quick military check-point set up, so don’t be startled. Just before reaching the small town of Santa Clara (with a gas station on the right just as you enter town), the Coastal Highway stretches off to the left and begins its journey to Puerto Peñasco.
The trip along the Coastal Highway to Rocky Point from Santa Clara, El Golfo, takes just over an hour.[/h]
