Topographic Map: Wentworth Springs

Access: From interstate 80 in Truckee, take Highway 89S and drive to Tahoe City. Continue south on Highway 89 from Tahoe City for another 4.2 miles to Caspian Picnic Area. Turn west on Blackwood Canyon Road. The road follows Blackwood creek for 2.3 miles, crosses the creek and then climbs 4.8 miles to Barker Pass. Pavement ends at the summit. The Powderhorn trailhead is 2.3 miles down the road from where the pavement ends.

Trail Description: From Barker Pass Road, the trail ascends through private land up to a broad saddle where it ties in with a logging road. Follow the road .2 miles to where the trail leaves the road. (It will cross the road a couple of times before reaching the wilderness boundary.) From the boundary, the trail descends through fields of wildflowers following the Powderhorn creek drainage. Volcanic rock of many sizes and textures can also be observed. At the bottom, the trail transects a large flat meadow and crosses Powderhorn Creek (caution is advised during high water). 300 yards past the creek, the trail ends in Diamond Crossing.

Two other trails connect to the Powderhorn here. They are the Hellhole Trail and 5 Lakes Creek Trail. These provide access to areas such as Hellhole Reservoir, Bear Pen, Shanks Cove, Five Lakes, Whisky Creek Camp, and Squaw Valley.
