Located in Devils Lake State Park, Wisconsin

Apex Adventure Alliance has been climbing rocks and cracking jokes since the early days—founded by local legend Tom Grieder in the late 90s and carried on today by a crew of passionate, chalk-covered guides who call Devil’s Lake home. We’ve been helping folks of all ages and abilities get vertical for decades, and we’re still just as psyched to share this place as we were on day one (possibly more, thanks to coffee and better shoes).

Our mission? To make climbing fun, safe, and just the right amount of challenging. Whether you’re brand new to the sport or working on your 5.12 head game, our professional, certified guides are here to show you the ropes—literally. We offer private full- and half-day adventures, anchor-building clinics, trad climbing courses, open group climbs, rappelling excursions, and custom programs for non-profit groups.

With over 2,000 routes snaking up Devil’s Lake’s iconic purple quartzite cliffs, this park isn’t just a climbing area—it’s a Midwest treasure (and our favorite playground). And while there’s no sport climbing here, there’s no shortage of bold moves, bomber gear placements, and unforgettable views.

So if you’re looking to tie in, level up, or just spend a day doing something epic—let’s make it happen. We can’t wait to welcome you to the gem of the Midwest and show you why Apex has been the go-to guiding service at Devil’s Lake for generations.
