To my knowledge, this route has never been ridden in full length. Be the first riders to ride this genuinely epic route.

Possibly the longest near continuous singletrack routes in the Cascades, spanning from the very edge of the Alpine Wilderness to the West, to the last bit of singletrack to the East, this route ranks among one of the hardest and LONGEST available without snaking around. This is a West to East, point to point route, terminating on highway 97 (Blewett Pass)

Over half of the Cascades in width, this route provides you with some of the highest alpine trails in Washington cascades available to ride a mountain bike on. Multiple passes and massive amount of climbing and descending.

This route is so tremendously long and arduous, consider having a sag wagon drop supplies or bike packing this route. There is water along this route in places, provided you filter. Speaking of water, numerous creek or river crossings are necessary. Do not ride during high water / storms.

Loose and dry but clear. Minimal horse poop and some moto ruts. After the intersection with De Roux spur the horse hoof prints have literally created a "washboard" trail feel in the sand.

Instead of starting the ride from the Salmon La Sac campground, we parked on the far end of Cooper lake, and first rode out to the Pete Lake trail. Pete lake trail was a lot of fun, although we passed many hikers on a Saturday. Next time I would reccomend a midweek ride, but all hikers were friendly. I dont think this trails sees many bikers. It was easy/intermediate technical XC riding, with small creek crossings, and some punchy climbs with root and rock obstacles. Pete Lake trail was a short out and back, as bikes are not allowed past a certain point, about 2 miles away from Pete lake. Next we headed down Cooper River trail, but right away we came across many down trees and overgrown brush, before reaching the campround area. We weaved through the campsites, and eventually came out to a road crossing at the lower end/base of the lake. Next time around, we should have started Cooper river trail at this point, since the upper portion was full of down trees and campsites and wasn't fun. Perhaps the trailforks map of this trails isn't accurate? From then on down to Salmon la Sac, the trail itself was in good shape, with good views of the river. More challenging than Pete Lake trail with more elevation change, and plenty of tight turns and punchy ups and downs. The ride finished at Salmon La Sac campground, and there is a rad swimming hole with rope-swing right at the bottom of the trail. We hitched a ride from a friend up to cooper lake to retrieve the car. Overall these trails were worth riding, since we were camping close by. But, I dont think they are quite exciting enough to justify if you travelling to ride them.
