Looking for vacation ideas? National Geographic released its annual list of the Top Tours of a Lifetime, which highlights the best guided trips around the world. Okay, so doing ALL of these trips would take quite a few years and a whole lot of money, but the slideshow above is a great way to spark your wanderlust.

National Geographic editors chose 50 expeditions as the best in their class, plus added another five journeys from the company's own guided adventures. Immersive, authentic travel experiences top the list: "In the ten years we've curated our annual roundup of the best guided trips, sustainable tours that reflect the National Geographic Society's mission to inspire, illuminate, and teach have proliferated," write the editors.
