Walden Bouldering

Do you have a membership or a 10-session pass at Walden?
Share your love for bouldering and introduce a friend who is new to the sport!
On Thursday August 20, your friend’s entry is on us—no fee, just fun.

This promotion is exclusively for first-time visitors to Walden. We’ll confirm this at check-in, as the free entry isn’t valid for current or former Walden card holders.
Please arrive together with your friend so we can keep everything running smoothly.

In our Walden Sessions, we invite talented DJs to set the mood while you climb, hang out, or enjoy a drink at the bar.

This edition, we’re welcoming back Heavy Tuna. He has played at our competitions and other Walden Sessions before, so he already knows exactly how to create the right atmosphere.

With more than 15 years behind the decks, Heavy Tuna blends house, funk, UK garage and drum & bass into his own distinctive style. From nights at Charlatan to sessions at Fonkel, he’s built a reputation for getting every crowd moving.

Get a few friends together for a nice evening of climbing, music and drinks!
