14 Of The Most Unforgettable National Parks In The World

Though there’s much to appreciate about this mountainous park, which forms a large stretch of the border between France and Spain, one unexpected feature stands out: the man-made Petit Train d'Artouste. Considered Europe’s highest railway, it’s reached by cable car and began as a way for workers to access hydroelectric dams in the 1920s. Now it takes visitors on a six-mile journey from the La Sagette peak to Artouste Lake.
