Easy 4WD (good-clearance recommended) up to the gate closure near Shoe Basin mine.

Driving Directions

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.

Winter Access

The Peru Creek (260) road is closed at the start.

Info: 4wd road is clear of snow all the way to the waldorf mine, but the rest of Argentine pass is mostly buried in steep snow. Road is doable in a subaru outback, although a handful of small trenches across the road had me scraping underneath the front of the car. No major damage but higher clearence would have helped. Traction needed for climbing or descending the steep snow drifts over the road past the mine.

Info: Just spoke with the Dillon Ranger District office. Said the Peru Creek road to the Argentine Pass trailhead is closed. Ironically, maintenance vehicle traffic to make repairs damaged the road. They are just now discussing repair options so it will be a long while before it opens again. There’s a possibility that the road might be closed all summer. Said the way to get status on the effort would be to call them. (970) 468-5400

Info: Rough 2WD the entire way to the trailhead. One area of standing water about two miles in but can be drove around. I wouldnt take a sedan up but if you have some clearance you will be fine.

Info: Road was in good condition this morning, just a few holes that were easily avoidable and the occasional water crossing. Made it up pretty easily in an AWD SUV with decent clearance - took about 50 minutes from to cover the 4.5 miles of dirt road. It was totally worth it, with tons of wildflowers and only a few other hikers on the trail (that is, until Grays).

Info: Road is dry all the way to the parking area except for a short section where the road is right next to the creek. Lots of potholes but anything higher than a passenger car will be fine as long as you don’t rush.

Info: A few large puddles around a mile past the start of 206. Otherwise, lots of potholes, but overall I’d put this more in the category of "rough 2wd", maybe comparable to 4th of July access road.

On a separate note: saw a few vehicles make it all the way up to Argentine Pass from the Waldorf Mine side. Also saw some genius 4-wheeling right over the tundra. Seriously people?

Info: Peru Creek road opened 6/22. Overall road is in good shape. Some avalanche debris covers the road about 1/4 mile from the Argentine Pass parking area. A couple vehicles plowed through but there is also room to park about 6 cars at the debris field.

Info: The gate at start of Peru Creek Road is still closed. Today I went there to check the status of the road.
Posted By: BillMiddlebrook
Info: Still open and dry. I called the USFS office in Dillon and they said they plan on closing the Peru Creek road on November 22nd, but I suspect it may close earlier if we get a snow storm.

Info: I climbed Mt. Edwards today from the west side (Horseshoe Basin / Peru Creek) via the Argentine Pass route. The only thing different from Bill Middlebrooks Southwest Ridge route description is that a good quality new footbridge has been placed over Peru Creek.

Info: Made it to the gate with my Elantra (2WD), but was a rough ride. Should be pretty easy with a 4WD.

Info: Peru Creek road gate is open and road is mostly dry and in good shape until you get close to the Argentine Pass TH. Some large puddles and small run-off streams before snow blocks passage within maybe 200 yards of the true trailhead. Wide shoulder just below this drift with room for 2-3 cars provides parking at the moment.

Info: Called Dillon Ranger district, and they said it will likely be a couple weeks until the gate at Montezuma Rd is opened.
Posted By: BillMiddlebrook
Info: Still closed/gated at the lower parking area, at the junction with the Montezuma road.

Info: The road is in good shape and is clear of all snow. 2wd accessible with decent clearance.

Info: Summit County Media Release:

A new 70-foot-span permanent bridge will be placed over the Snake River at the site of the washout, restoring vehicle travel along Montezuma Road in its pre-washout route.

the bridge and abutments to the site in eight pieces and are tentatively scheduled set them on Wednesday and Thursday,Aug. 27 and 28. Montezuma Road will be closed to through traffic for extended periods on these two days, to allow crane operators to efficiently install the structures.

Info: Access to Peru Creek, Chihuahua Gulch, Horseshoe Basin, and Argentine Pass is closed until further notice. Last week the Snake River washed out a 45-foot length of road just west of the Peru Creek Trailhead, 0.6 miles west of the entrance to the town of Montezuma. The flooding caused severe road damage to a half-mile stretch of road west of the washout site, with the entire south lane destroyed in many spots. Road & Bridge will work throughout the summer to rebuild the washed-out section of road. Access for the general public may remain closed throughout the summer. Summit County officials announced they have closed Montezuma Road until further notice, prohibiting access to trailheads, trails and roads on national forest lands east of the flood site. The closure applies to skiers, snowmobilers, hikers, bikers, off-roaders and all other recreationalists looking to access Peru Creek Trailhead/Peru Creek Road, Chihuahua Gulch Road, Chihuahua Lake Trail, Sts. John Road, Webster Pass Road, Deer Creek Trailhead and Deer Creek Road, Morgan Gulch Road, Cinnamon Gulch Road, Argentine Pass Trail, Lenawee Trail, Warden Gulch Road, access to Grays and Torreys peaks, and the Continental Divide Trail from Grays Peak to Whale Peak. The easternmost turnaround location for vehicles with trailers is at a roadblock 3.12 miles east of the intersection of Highway 6 and Montezuma Road. Recreation-specific updates can be found at the White River National Forest website (, by navigating to the Alerts and Notices page using the button in the website’s upper right column. More information is available by calling the Dillon Ranger District at 970-468-5400.

Info: The slide has been cleared. Easy 4WD now.

Info: Peru Creek Rd is closed after the Cinnamon Pass junction due to a big landslide. The road crew working down lower said it happened Wed, and they don‘t have an estimated time to reopen the road.
Posted By: BillMiddlebrook
Info: Road open and dry to the trailhead. It‘s a bit rough this year but good-clearance vehicles should be OK.
Posted By: TravelingMatt
Info: Still gated. Snowfields start past the first creek crossing and become continuous above the turnoff near the Pennsylvania Mine. Still a ways to go.
Posted By: TravelingMatt
Info: Gated at Montezuma Road. Wouldn‘t count on it opening by Memorial Day.
Posted By: BillMiddlebrook
Info: Still open (4WD) to the upper trailhead. The road had some icy patches and packed snow, but I had no problem driving all the way to the Argentine Pass trailhead in my 4WD pickup. I doubt it will be open after the next major snowfall.
Posted By: TravelingMatt
Info: Still open and passable to TH, upper half is 4wd/clearance as always. About 60% dry with the remainder mud/snow/ice. Does not impede driving too much but watch the road and take it slowly where necessary. Last mile or so to parking area is almost completely dry.

Info: Trek to the Waldorf Mine may be quite an experience for you. The road is rough but passable with a standard SUV with high clearance and 4WD. I drove in my Chevy Blazer in 4WD from the pavement to the mine. Make sure to stay on FS248-1 NOT 1B this will lead you to a creek bed. I would do the drive in the daylight for the first time to prevent navigation issues like I had. Lots of traffic on the weekend 30+ vehicles, be prepared on the narrows.
