A small collection of boulders nestled between two prominent cliffs in the "crotch" of twin valley lake. Some classic lines, some only ok. Nice views from the ridge. The bluffs are easily visible from the far east end of twin valley campground.
There is another smaller boulder just south (50ft) with 3 potentially good lines on it. They look fun.
Due east of Twin Valley Campground you can easily see two large rock outcroppings. The boulders are right on the hillside right between these.
Park at campsite 271 in the twin valley campground. Hike 50 paces down the wide trail and you should see a small foot path on the right. Take this footpath down the bluff until you hit the horse trail (5min). Take the horse trail left. This trail splits quickly, take the right path (past a wooden bench). At the next intersection take the right path again. Follow this trail for about 50 feet. When the 4ft burm on the left gets to ground level walk into the woods toward the bluff. The boulders are a very short distance off the trail.
For those who can't follow directions (those who cant find the ABC boulder:) See the obvious bluffs described earlier, aim right between them, and walk straight through the woods until you hit the boulders.
Mountain Project's determination of some of the classic, most popular, highest rated routes for The Complex:
Thin! Stand start and move up a series of small/sharpish pinches. Bump to a good pinch just off the right arete, and move left onto more thin bad holds. Either make a final deadpoint to a minipocket out left, or dyno for the huge jug at the top. Super fun route! ...[more]Browse More Classics in WI
I hiked around the whole bluff, and the rock was either too small or big and chossy. Could be a few other lines in there but would need some work. Well worth the hike in to check it out, the established problems are great. Beware, the deer ticks are out and thirsty.
