This trailhead is used to access both Argentine Pass and Horseshoe Basin. Take U.S. 6 to the west end of Keystone. If you are driving east on U.S. 6, take the exit for Montezuma Road before U.S. 6 begins its climb to Loveland Pass. If you are driving west (from Loveland Pass), turn left into the River Run area of the Keystone Ski Resort. Take another quick left and drive a bit to get to the Montezuma Road.

Drive ~4.3 miles on the Montezuma road and turn left on the 260 (dirt) road. There is a large parking area at the start of this road. From the parking area, drive 4.5 miles along Peru Creek to the Argentine Pass trailhead at 11,050', just below the Shoe Basin Mine. The road is gated beyond the trailhead.


From the parking area, walk northeast a short distance up the road and pass the gate, near the Shoe Basin mine - 1. Continue less than 0.5 mile and turn right onto the marked Argentine Pass trail - 2. Cross Peru Creek ( 3 but now there's a bridge, I think) and continue southeast on the great trail. After weaving through willows, traverse a slope ( 4) and exit the trees, near 11,600' - 5. Above 11,800', turn sharply left and continue north along Argentine's west slopes - 6. Cross a large gully ( 7) and another, more-rugged one, near 12,800' - 8. Ascend a long stretch ( 9) to reach Argentine Pass at 13,200' - 10.

Argentine Pass is near the center of the long ridge between 14ers Mt. Edwards (north) and Argentine Peak (south). Turn right and hike along the Continental Divide, towards Argentine - 11. Descend about 150' to the lowest point and follow faint trail segments along the ridge - 12 and 13. From a 13,449-foot point ( 14), descend a short, steep pitch and continue along the ridge to reach the summit - 15, 16, 17 and 18.
