A wonderful trail that can be ridden in either direction and connects the Uplands and Hummocks trails to Ousel Falls and the Yellowmule trails. Riding from town, head east on Aspen Leaf Dr, dropping down to the South Fork of the Gallatin, and climb a hundred yards to the Uplands and Hummocks trailhead. Ascend the Uplands trail to the apex of the climb where you'll find the signed intersection with Ralphs Pass. Jump on Ralphs pass and enjoy. in about 3/4 of a mile, take caution as you enter the switchback section that will test balance. The cruise continues with occasional winding boardwalks and a few bridges as you pass through shaded forests. The ride concludes with short little climb to Ousel Falls trail, where you can continue up to the Yellow Mule trails or take a right back up to the Ousel Falls parking lot.
Reverse the directions for an equally challenging back to Uplands.

Access Info

Access is either via Uplands Trail or Ousel Falls trail.
Uplands: From town center take Aspen Leaf Dr east, past the community stage, across the South Fork of the Gallatin River and up to Uplands and Hummocks trailhead. Ascend Uplands to the top where you will find the intersection with Ralph's Pass
Ousel falls: From Town Center, head up Ousel Falls Rd, or jump on the trail paralleling Ousel Falls rd, for nearly two miles and turn left into Ousel Falls Trailhead parking lot. Descend gravel trail down to river, cross bridge and Ralphs pass on the left 100 yards past the bridge.

 Those switchbacks! A good challenge to clean them all going uphill. I would recommend going the other way so the switchbacks are downhill (from Upland to Ousel).
