Iron Creek to Grandjean is a 29.3-mile out-and-back through the Sawtooth Wilderness located west of Stanley, Idaho. In this route, you follow Iron Creek - Stanley Lake Trail #640, ascend Observation Peak, then take Trail Creek Trail #453 to reach Grandjean Trailhead. 

The route passes through fragrant pine forests, peaceful meadows, scenic valleys, flowing creeks, and sparkling alpine lakes. It can be completed as a long day hike or (most commonly) as an overnight backpacking trip. Scenic backcountry campsites are plentiful along the route and permits (though required) are free and available at the trailhead. 

Additionally, the route intersects multiple trails in the wilderness, making it easy to adjust the distance based on your needs.

DESCRIPTION

The trail begins in a forested area and follows Iron Creek for about a mile before starting a climb up several switchbacks towards Alpine Lake. Here the trail becomes rocky and exposed, but filled with rewarding scenery and views of the Sawtooth Mountains.

After 4 miles, you will reach a junction on the left that leads to Alpine Lake. To remain on the Iron Creek - Stanley Lake Trail, stay straight. About ½ mile later you will reach Sawtooth Lake, one of the largest and most spectacular in the region! The lake offers plenty of camping space, but it is popular and tends to fill up on weekends. 

At the next junction stay straight to ascend Observation Peak (or skip this part to shorten the distance) and then take the Trail Creek Trail south and then west to the Grandjean Trailhead. 

Return to the Iron Creek Trailhead by retracing your steps (a second summit of Observation Peak is optional and not included in the overall distance of this trek).

IRON CREEK TRAILHEAD

This route begins at the Iron Creek Trailhead, 5.5 miles west of Stanley, Idaho via Forest Road 619, and runs east to west. Parking is plentiful, but does fill up on the weekends. You can also complete the route from west to east and park at the Grandjean Trailhead.
