Area Status: Open

This 3.3 mile trail is within Crooked Creek Trail #3100 (area is unavailable). It is an access trail to the Crooked Creek Canyon. The trail descends 1700' in 3 miles, but it is well graded with many switchbacks.

Three Forks Trail is one of the first trails that opens in the spring. Because of its low elevation and southern slopes, the trail dries out quickly and becomes very dusty, but Crooked Creek at the bottom of the trail awaits to cool down travelers. The view of the Crooked Creek Canyon and the Wenaha-Tucannon Wilderness is breathtaking.

The access roads to the trailhead are graveled.Alert: The trail is notorious for rattlesnakes, so caution is a necessity.
