I've crossed into Mexico through this border crossing several times, but I have never used it to…read morecross back into the United States. I usually crossed at the San Luis border crossing, so these five stars are for my experience heading south only. Driving from LA to Mexicali is an adventure... a 4-hour adventure to be exact. Two hours south on the 405/5/805, and then two more hours on the 8/98 west. Crossing into Mexico is a breeze, as long as you have nothing to declare, nor look like a trouble maker. Once across, you'll find yourself in downtown Mexicali. Coming back to the US at this border station would benefit you most if you have Sentri. If you don't then you will only have a limited window to cross using the Ready Lane. Else, it's the general lane for you. I have my passport card, but I am still in the process of getting my Sentri, so I don't use this border crossing. There is a sister station: the east crossing. But much like this border station, the eastern crossing also has a small window in which all its lanes are open. This is all surprising, because San Luis Rio Colorado is a far smaller town than Mexicali, yet the San Luis border crossing has all three lanes open 24-hours a day. Keep all this in mind when you plan your trip.

Waste of time Way too slow passing cars through…read more Unnecessary stops and long waits in between cars. Stopped all lanes to smash the cars together, open all the trunks, wasting even more time. No one is moving, no direction at all.

This may be the busiest post office in a small town. Super huge PO Box section (accessible 24…read morehours a day). Many people who live in Baja Norte keep PO Boxes here (this is literally about 10 minutes walk from the border). It is always busy, the parking lot can be a little cramped at times. Personnel are very nice and helpful but speak only limited English (some are fluent in both languages). It is much easier to just speak Spanish here but be forewarned if you don't speak Spanish may be a little harder to find someone to help you. The only thing that sucks is it doesn't have one of those machines where you can buy postage and prep your own package for mailing.
