Cascade Pass from the trailhead outside out of Marblemount at the end the road at Johanisburg Campground, one way, to High Bridge just outside of Stehekin at the north(west) end of Lake Chelan: Great Hike, lots of Marmots in the high country and bears down in the Stehekin valley. Bear wires or Bear boxes at every desgnated campground. Be sure and use them for food and anything else that has an oder(soap, deoderant, toothpaste, etc) because the bears are out there. We sighted about six bears but had no problem.
Thetrail up to Cascade pass from Johanisburg is steep but not bad because of nicely spaced switchbacks. Highly recommend an early start and plan on camping at the Sahale Glacier campground at the high end of Sahale Arm, instead of Pelton Basin Campground. Its an incredible camp sight situated on a ledge on the side of the mountain. You won't forget it. 2nd day, Skip Pelton basin and drop down to Basin Creek Campground for your second night. This hike down to Basin Creek is a classic series of high altitude valley views with a marvelous lunch stop at the doubtful Creek water falls. (check out the pool above the lowest cascade for a chilling but zesty plunge. The 3rd night is best taken at Parker Creek campground or one of the lower campsights, then hike out the fourth day to High Bridge where you can catch a bus back to Stehekin at 12:00 noon every day (check with the ranger station on the bus schedule in the event of schedule change. You have to hike to High Bridge because the Stehekin River has severely washed out the road above High Bridge.
Enjoy this opportunity to experience the high Country then visit the Golden West Ranger Station in Stehekin on your way home to see the early Native American, homesteading, and mining history of the Pass and Valley.
