Natural wonders arrest us. Few experiences rival standing toe-to-toe with majestic canyons, vast ice flows, or banded deserts that remind us just how remarkable this planet is. Natural wonders predate humanity and resist human efforts to tame them, leaving their mark on every generation.

The most interesting places in the world are not just pretty pictures. They are homelands, inspirations, and launchpads of adventure. We haven’t completed our circuit around the world yet (still working on it), but we’ve covered five continents and though it was worth the effort to share ten outstanding destinations that challenged us, moved us, and left lasting impressions. Seek them out. We have suggested distinct, engaging and helpful ways to experience each wonder actively and meaningfully.
