Why We Love International Mountain Day
They're ever-changing
While mountains don't move much in the course of human lifetimes, their nature dictates that they're always changing, and there's something intangibly intriguing about things that are in a constant state of flux.
They offer an escape
While bird's-eye views are reserved for... well... birds, mountains give people the ability to get closer to the sky without ever leaving the ground. Until the creation of aircrafts, the highest elevations ever reached by humans were made possible by mountains. Even though they've now been surpassed, they still offer an incomparable escape from the doldrums of everyday life.
They're pretty much playgrounds for adults
The kids can keep their jungle gyms — we've got mountains. Between the various rivers, rock faces, and viewing points, mountains are like playgrounds for grown ups!
