This is the best spot to cross into Mexico if you’re just looking to do a short day trip. You can park on the US-side for $4 (as of 5/11/24) and walk across to the MX-side for another $1/person. You walk across the bridge, over the Rio Grande and you’re there. There is a bag scanning area as you get to Mexico but it’s not like TSA, it’s more like a going-to-a-concert type of check. Be ready for the onslaught of vendors offering dental work, optometry appointments, laser hair removal, medications, etc, etc… I just “estoy bien” my way through it. On the way back there’s a small fee… it’s 30¢ that you put into a little turn-dial thing, so you will need change. There’s a kiosk there for people who need to convert $ to ¢ but it’s chaos… much easier if you have it on you already. (Side note: It’s been 30¢ for a few years, don’t know if that changes as frequently as the parking prices). This last time I went (5/11/24) they had A LOT of homeless people on the bridge MX-to-US side… I don’t know why they were up there, (it was past the 30¢ fee area too which had me wondering if they’re paying to be on that side IDK). They weren’t begging or doing anything wrong it was just surprising and hard to walk past.
