8 miles of rocky descent. This trail can be ridden from the top if you start at the Upper Sisson Callahan, however many riders shuttle to the halfway point using 41N53 road. This trail has some flowy sections, but the majority is one big rock garden. Your hands will be hurting.

Top Half: The top starts out flowy with several unexpected switchbacks before it mellows out and follows the river. There are a few straight smooth sections in the middle and then the trail gets rockier as you get closer to the second half.

Lower Half: Many people shuttle this and some ride the road to the second half. This half starts out flowy with some rock gardens. About halfway down it gets really close to the river with some exposure. The rest of the trail is rocky all the way to the bottom.
-----
The trail ends in the middle of nowhere. If you want to ride to the North Shore side of the Lake, stop near the bottom at the little turn marked with rocks. Then, climb through the river to the road on the other side. Follow this road and you will at the North Shore. If you want to ride to the WA Barr Road, keep on, passed the rock turn, and cross the river on your left. This is kind of a free for all and there isn't a spot that's better for crossing. So pick a spot before the trail ends and cross the river. Once you have crossed, ride through the trees until you reach a road(s) and follow that road to WA Barr Road.

Access Info

If you want to ride the whole thing, you can ride the Upper Sisson Callahan. Shasta Gravity offers shuttles to the Upper Sisson Callahan. Once you have made it to the top of Upper Sisson Callahan, you take the trail down the other side of the hill. It should be obvious and there should be a sign that says Lake Siskiyou. (You could also shuttle to the lower half and hike up to the top of the upper half).

If you want to ride the lower half, drive/ride West A Barr Road past Lake Siskiyou until you reach a small, narrow bridge over the creek. Then, take a right, right after the bridge and stay right at the fork onto 41N53 road. Follow the main road until you reach the second ford across the creek. The trailhead (going down) is on the right a few hundred feet before the creek crossing. The bottom of the upper half is on the left, right before the creek crossing. Note: 41N53 is a bumpy and rocky road.
