The Biggest Climbing gyms in USA and EUROPE

We’ve never had the goal to set records of this kind. However, while doing our job completing projects for our clients, it turned out that the biggest climbing gyms in many countries are actually designed and built by us. Here some of them:

The biggest climbing gym designed and built at once

With its 6377 sq.m (68,641 sq. ft) plywood panels, Kletterzentrum Innsbruck is the biggest climbing gym in the world that was designed and built in one push at this size. There is another climbing facility, DAV Munich Sud, that features the largest total climbing surface but it was designed in a much smaller scale in 1989 and had multiple extensions added throughout the years.

Kletterzentrum Innsbruck’s design takes about 8 months of constant collaboration between Reinhold Sherer, Austria’s national team coach and gym manager and the Walltopia architect. They discuss the wall design with professional athletes like Killian Fischuber and Jacob Schubert, in order to create walls that fully correspond to the expectations for a training facility and competition arena in the same time.

Walltopia team took about 6 months to assemble over 112 tons of steel structure and plywood panels at height of up to 17 m (55 ft). To date the climbing facility is being used for training camps for national climbing teams from all over the world, it has hosted many European and world championships. The gym has indoor and outdoor sections offering over 800 routes for casual climbers and professionals alike.


“I must acknowledge that the collaboration with Walltopia was very successful. It is remarkable how professionally they finished the job of such a huge scale making it what it is today.”

The biggest climbing gym in the usa

With its 3995 sq. m (43 000 sq.ft) climbing surface, Earth Treks climbing gym in Englewood, CO is the biggest climbing gym in the USA to date. Part of a gym chain with 16 locations in the states of Oregon, Colorado, California, Virginia and Maryland, this gym was completed in 2018. Interesting fact is that the building that hosts the facility was not high enough to feature the desired climbing facility. Instead of compromising with the climbing wall height, the owners decided to raise the roof with a few additional meters costing them significant constructional effort but allowing them to have the climbing gym they are dreaming of.

The climbing wall design is created by Jason Kehl, a famous figure in the climibing industry with whom Walltopia collaborates for many projects.


“In the last 6 years we have actually built 7 locations with Walltopia. Their ability to faithfully provide a wall design that is cutting edge, on time and enriching to the community, is truly a step above all their competitors.”
