Having just one night to spend in El Paso, I was keen to see the border crossing over to Mexico. I woke early on the Sunday morning and took a walk from the Camino Real down S Santa Fe Street about 9 blocks to where the high fences of the border pass under the road bridge which brings approved traffic over the border to/from Mexico.
The official border runs along the middle of the Rio Grande River here but it is little more than a storm-water drain and not really visible from the roadside.
I turn left onto Cesar E Chavez Border Highway, shortly after which a vehicle from the US Border Patrol pulled up and enquired as to my activities; quickly showing my camera and offering access to my British passport (along with my accent) convinced the officer that I was nothing more than a tourist.
A little later, the bridge was a mass of people crossing the border as they headed to El Paso ready for the shops opening.
Crossing into Mexico is a must but there are many things to do in the area. The trolley from the civic center crosses into Mexico and drops off passengers at several stops. The price allows reboarding and allows the visitor so see several part of Juarez with out having to walk too far or risk driving in a very different world.
Bargaining is something many Amereicans have never done but it is a fun experience with a little practice. Don't but the first time you see something you like. Look at several places and then start by asking for the best price. It may be close but it usually won't be the best one. Don't worry you cheat the vendor. They've had lots of experience. You'll have fun if you think of it as a game.
Crossing the border into Mexico... I strongly recommend using the walk-over bridge. It's quite a walk, but you'll find a lot more interesting stuff.
This is where all the good shops are. You'll find authentic Mexican goodies as well as touristy stuff.
