Blue Canyon Trail is a remote point-to-point route from Crown Valley Trailhead into the canyon country of Kings Canyon. The full one-way line is about 18.8 miles: roughly 7.8 miles of access to the Blue Canyon junction, then about 11 miles on the named canyon trail. That section alone climbs about 3,700 feet, drops about 2,300, and reaches 9,262 feet. Allow around 15 hours of moving time for the full line and plan it as a backpacking trip. The mapped east end has no road access or confirmed pickup, so decide how you will continue or return before leaving. Retracing the same line is about 37.6 miles total. Overnight wilderness permits are required, and the trailhead quota applies year-round.
