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.
1. The mighty Excalibur
Where: Bjoeks, The Netherlands
What's special: A climbing tower that's just over 120 feet high with a 36-foot overhang. There's even a competition going at the moment —climbing champ Jorg Verhoeven set a 9a route on the wall and the first person to redpoint it wins €1,000.
2. The dam route
What: A huge dam
Where: Diga di Luzzone dam, Blenio, Switzerland
What's special: This 540-foot dam has been turned into a climbing wall. Climbers need to use a ladder to get up the first 20 feet to the holds, but after making it to the top they can catch spectacular views of the Alps.
3. Indoor ice climbing
What: Indoor ice wall
Where: Ice Factor, Kinlochleven, Scotland
What's special: Climbers can practice their technique indoors all year round on this 39-foot-high wall. It's the biggest indoor ice wall in the world, based on the famous West Highland Way trekking route.
4. The fairytale wall
What: Designer wall
Where: Tokyo, Japan
What's special: This wall blends the high fashion of Tokyo with outdoor activities. It's based in the Illoiha fitness club and uses interior design elements to create the wall, allowing people to try out the sport easily.
5. Frozen grain silo
What: Ice-covered grain silo
Where: Cedar Falls, Iowa
What's special: These grain silos have been converted into awesome ice-climbing routes. The idea came from Don Briggs in 2001, who worked to perfect a way to rig hoses in order to make ice in cold weather.
6. Color climb
What: Colorful climbing walls
Where: Extreme Edge, Auckland, NZ
What's special: Climbzone is perfect for kids — it's a riot of color. The complex has walls for adults too, though!
7. Against the grain
What: Grain silo climbing
Where: Upper Limits, Bloomington, Illinois
What's special: Enjoy a unique climb inside 65-foot-high grain silos. There are three round silos, and two interestingly shaped ones that allow chimney climbs. The center also has an outdoor wall, bouldering cave and main area with loads of routes.
8. Cathedral climb
What: Climbing inside a remodeled cathedral
Where: Manchester, UK
What's special: Nestled into a former victorian cathedral, these walls really do soar to the sky. And they're bathed in the lovely multi-colored light from the stained glass, too.
9. Go psicobloc
What: Deep water soloing
Where: Utah Olympic Park
What's special: Dreaming of deep water soloing in lush locations, but can't get there? Here's a way to give it a go, artificially. Routes at the Utah Olympic Park hang over water — pretty awesome.
