Looks like there is a bouldering gym opening in an empty former bakery on Center and Holton (2678 N. Holton St.). There is a sign in the window suggesting it is currently under construction, with no official opening date announced.
We attempted to contact the organizers for more information, but they have not returned a comment.
Bouldering is a sister activity to top-rope rock climbing, where shorter but more technical routes means ropes aren't necessary. But it is still a fun way to get into shape, think dynamically, and enjoy consistent success (no matter how small).
Solow Bouldering Club could find synergy with Riverwest Strength and Conditioning next door.
Stay tuned to OnMilwaukee as more information arises, or check out the website at solowmke.com.
