Just a few short hours across the Texas-Mexico border lies Monterrey, Nuevo Leon. A modern industrial city with a thriving economy, Monterrey also happens to be surrounded by the rugged Sierra Madre Occidental mountains, reaching over 12,000 feet high. Just to the south of the city lies Los Cumbres de Monterrey, a national park with hundreds of miles of roads and dirt tracks that snake through the deep canyons and gorges.
