In addition to its northern border with California, Mexico also has a southern border with Guatemala, which stretches thousands of miles along the Pacific coast. Tourists began arriving on this coast in the 1920s, when most of the coast was inhabited by small fishing villages. This part of the world is full of things to do, particularly for active types. Scuba diving and snorkeling are among the water activities available, and there are countless beaches nearby. Culture seekers should consider Mazatlan’s historic center, while foodies should check out Puerto Vallarta’s food culture. The Baja Desert even offers camel rides.
