Inside a silo climbing wall

9 of the World's Most Unique Climbing Walls

From indoor ice to empty grain silos, these are the coolest artificial climbing walls in the world.

When it comes to artificial climbing walls, the sky is (literally) the limit in terms of creativity and design. You could take the easy route (an approach not common in the climbing community) and just build a static wall, or you could think outside the box and run the holds up the inside of a grain silo or even freeze the whole silo to create an awesome ice climbing training spot. How about the dry side of a dam? It's just sitting there, taunting you.

The walls featured below are definitely some of the most unique climbing walls to be found. So get your chalk bag ready, you're going to want to climb after seeing them.
