This reply is about 6 months after the original post, but I'd like to share some experiences with those interested in heading into Mexico from Presidio, Texas. I am a resident of Presidio, so my travels across the border have been numerous.

First of all, entering Mexico at Ojinaga is usually quick. Avoid major holidays, though, as even this smaller crossing can get really busy. Mexican insurance is available on both sides of the border. Presidio also has three motels and Ojinaga has several.

Once you clear customs and immigration (getting all the necessary paperwork taken care of) you can go on into town to grab a quick bite to eat, or to change money. Several banks and ATMs are located in or near downtown.

When you are ready to hit the highway, you'll have two route choices, soon to be three (kind of). At present you may go on Hwy 16 to Chihuahua City, which is about 145 miles. This route goes through Coyame which is a nice rest/fuel stop a little over an hour past Ojinaga. Another route is to leave Ojinaga and head towards Camargo at the last traffic light, leaving Ojinaga. Going to Camargo is faster and less travelled, but there are no other towns for 150 miles. The Camargo road will very soon have a junction that leads (over a non-mountainous route, following the railroad)to Hwy 16, leading to Chihuahua. I recommend going to Chihuahua City if you want to take your time (things to do/see in Chihuahua, Sta. Eulalia, Cuahutemoc, and Copper Canyon further west). If time is of the essence and 150 mile is no range problem, take the Camargo road.

Eventually both routes will lead to Parral in southern Chihuahua. Getting to Parral will take at least four hours (from Ojinaga). Parral itself is an interesting town. Its biggest claim to fame is where Mexican revolutionary, Panch Villa was assasinated.

At the end of a full day of riding, you should end up in Durango. Don't try to go on to Mazatlan in the same day you left Ojinaga. You will be way too tired and you will end up riding some demanding roadway way after dark.

The road between Durango and Mazatlan is called El Espinazo del Devil (The Devil's Backbone). The road is aptly named with countless curvy and hilly spots. Taken at a reasonable pace, though, this roadway is a motorcyclist's dream. It should take you about 6-8 hours to make the ride from Durango to Mazatlan.

Once in Mazatlan, there are many, many hotels to choose from. The Presidio contingent (a bunch of Presidio school teachers) usually likes to stay at the Hotel Belmar, where you can park your bike just a few feet away from the front desk.

Happy travels!
