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

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

Info: Road is passable by 2wd but there are a lot of pot holes and one snow packed area but 4wd not needed. Most pot holes can be driven more easily by utilizing the edges of the road.

Info: Pretty much same as last updates. Adding pics.
Potholes and bumps. No steep sections.
Some places where a bit of clearance might be recommended but my RWD F-150 made it fine.
Saw a sedan at the trailhead (that car may have still scrapped somewhere?)

Info: The usual pothole and washboard conditions. IMHO 2/6.

Info: Definitely a "3" with some mild pot holes, rocks, and few spots you better slow down on. 2WD can make it easily if you just pay attention.
Best part was only 5 cars in the parking lot at 7am on a Saturday.
Note: The road ends at the parking lot. Save yourself the 5-point turn and don’t explore around the corner. A couple guys in a Ford Escape messed up the turn and had to be towed out today.

Info: This road shouldn’t be ranked a 3 imo... definitely don’t need 4WD and clearance isn’t all that critical either. A "2" feels right based on other similar rated roads I’ve driven. Based on my experience here last year I had no qualms driving my ~6" clearance 2WD wagon all the way to the parking lot. A Mini Cooper pulled in shortly after me... Most other vehicles there today were your usual AWD crossovers, trucks, etc. The road is bumpy with rocks and small potholes all over, the last stretch from the road fork (for Penn. Mine) to the TH is the worst. You’re going to go slow no matter what vehicle you drive, but moderate clearance is sufficient as long as you know how to pick a line here and there.

Info: Pesky snowdrift 0.25 miles from TH. It has big tracks but easy for most vehicles to get stuck. Not worth it, parked fine just before it.

Info: One can drive right up to ~0.25 miles from the Argentine Pass trailhead. You can see the Shoe Basin Mine from the first snow patch on the road. By the tracks, some vehicles got through this short one. There is a second, longer snow patch on the road with no evidence of anyone having driven through it. It isnt worth going up the first snow patch to park slightly closer. Also consider that as the day warms up, the snow gets really slushy. I saw a truck attempt to go up the first snow patch & with the slush, it was like the truck had zero traction as the wheels spun in place. The snow will likely not last past June.

Info: Peru Creek Rd is dry/passable till 4.3 miles from the gate. After that a significant snowfield crosses the meadow. Dont go beyond the split with 262 if uncomfortable with a 3 pt turn, or have the clearance to back up for a long ways. Had to convince a Jeep Wrangler to turn around, since I wasnt backing the Subi down the rough road! Theres enough room for it right at the start of the snow. Will likely melt more before the next weekend.

Info: Dry to parking area, AWD accessible.

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.
Posted By: E_A_Marcus_949
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
