A lthough the highway system is not up to American and Canadian standards, many excellent highways can be found in Mexico, and many other roads only require a little patience to take you to marvelous sights. Volcanoes, vast deserts, tropical jungles, miles of deserted beaches, ancient ruins, modern cities, quaint villages, and posh resorts, can all be found in Mexico. Check Driving Distances. Mexico has an excellent bus system. First class buses are a preferred way to travel for many North Americans.
Trains also are available, but the standards do vary.
For many people, air travel is the way to go. There are many excellent airports in the country. All resort areas are served by airports, and many people cruise by boat to coastal destinations. If you have Mexican insurance, that is proof enough, and you won't be held unless a death or serious injury occurred. You can purchase Mexican insurance in the United States near the border crossings, or over the Internet.
