Argentine Pass Trailhead


Road Difficulty

Easy 4WD, good clearance recommended. 3   (0=Paved, 6=Very Difficult 4WD)
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

Closed at the start of the Peru Creek road.

Info: I was the last spot around 1-2PM. 2wd capable, I personally wouldn’t. Limited dispersed camping & easy in a truck

Info: A lot of holes to dodge, and a tad rocky at times, but nothing terrible. Easily done in a crossover-type vehicle, and there were even a couple mid-clearance sedans at/near the TH that made it fine.

Info: Road is in summer conditions, no notable issues. It’s even Subaru-able if so desired!

Info: was able to drive to the Leavenworth Mine without issue, but did not attempt past there, as the east faces of Edwards and Argentine are still holding snowfields.

Info: Drove a bit past Chihuahua Gulch, then turned around. In a Subaru Outback it was a bit scary because the road was very icy and we were sliding quite a bit. Tires were not new but not bald either. Not sure when they close the gate at the winter TH but based on conditions expect it to be soon.

Info: Snow sticking and prevalent in parts. Acura SUV did just fine all the way to the parking lot/mine area. Saw an older Outback up there as we were leaving. Good traction is all you should need for now though.

Info: As of sunday snow is sticking on about 50% of the road. Still okay in a passenger vehicle as long as you have good traction, next storm will definitely change this

Info: Dry, summer conditions. Some dips but nothing major. Made it all the way to top of th in a Honda HRV, 2wd manual transmission.

Info: All clear and ready to go! The last mile up to Argentine Pass TH proper is the roughest - any car with clearance will make it just fine but I’d be worried about a sedan, however it’s all about the driver, so go at your own risk. The rest of the road is a typical dirt road but in pretty good condition. Some large puddles to go through but nothing too deep.

Info: The road is now open all of the way to the trailhead at the gate. Avalanche areas all cleared. 4WD with clearance makes it easy drive. Rains yesterday made it a bit more bumpy with exposed rocks on the way down compared to the way up earlier that day.

Info: To give an update from CheapCigarMan’s post on 6/11 - I called the Dillon Ranger District office (970-468-5400) today, and the road is closed and will be for some time. It’s in the plans to fix it but there’s all sorts of damage - avalanche debris, power lines down, road cracks, etc - that will take a lot of time to fix. They’re still working on the plans. If you want to get up there, you’ll have to park below and add the extra mileage.

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.
