These Incredible Hiking Destinations Should Inspire Your Next Vacation

Ciudad Perdida, or the Lost City, is older than Machu Picchu, and the hike to the ruins is not for the faint of heart. It takes four to six days and is over 27 miles of hilly hikes through hot, humid jungles and mountains. The path even contains several river crossings — but if you're up to it, the Lost City Trek is one of the most spectacular hikes in the world.
