Getting There
The Border

Where the Northern border of Sonora adjoins the southern
border of Arizona, there are four main border crossings:

Nogales, AZ/Nogales, Sonora

Douglas, AZ/Agua Prieta, Sonora

Lukeville, AZ/Sonoyta, Sonora

Yuma, AZ/San Luis Rio Colorado, Sonora

Mexican border towns can be fun places to shop and enjoy a
taste of Mexico.  However, they can also be dangerous.  As a
general rule it's best to travel in groups, and during the day.

Sonora's border towns have generally not had problems with
crime and violence to the extent that border towns in other
states have experienced, but it's always a good idea to check
for travel advisories before entering Mexico.

And while it's easy to get caught up in the "intoxicating"
environment, be careful about drinking too much, stay in
places where there are other tourists, and always be aware of
your surroundings.
