Aconcagua Day 5: Trek to Plaza Argentina Base Camp

Posted on February 10, 2025February 12, 2026 by Backcountry Fever

It was only our third day on the trail but after today, we will arrive at Plaza Argentina Base Camp.  The day began with a frigid river crossing that involved several strands to navigate.

river crossing early morning

The river wasn’t more then knee-deep.  However, the water was pretty cold at 7 in the morning with its glacial headwaters only 10 miles upstream!

The option to ride across on a mule was offered, but the majority of us wanted the full experience.

These gentle animals were so strong, they made the job they performed look so easy.

Looking back towards our last camp, we slowly and steadily worked our way up Relincho Canyon.

Filling our water along the way — so far so good with it still all unfiltered.

Peeking views of Aconcagua started to appear not long after.

In 9 more days, I hope to be taking a similar picture from up there!

A second river crossing at 11,800′ was much easier and refreshing now in the warmth of the sun.

My feet were doing great after the first 20 miles, thanks to my favorite Injini socks!

More guanacos at these higher elevations.

What a good group to be doing this expedition with — something that could easily make or break an expedition of this kind.

The mules were already on their way down after making their final trip to deliver our gear to base camp.

Very pleasant temps today above 12,000 feet.

Onward and upward with hopes for weather like this on our summit day!

onward and upward

Soon after, we reach the top of Relincho Canyon and arrive at Plaza Argentina, Aconcagua’s base camp on 360° Traverse side.

We made it… and feeling great!

Welcome to Plaza Argentina

Today’s stats from my phone (since the track on my watch accidentally ended early!): 3,255′ of elevation in 7.5 miles.

Here are some totals for this lower portion of the 360° Traverse thus far:

LOWER TREK TOTAL 25.35 mi (40.80 km) 6,546 ft (1,995 m)

Couldn`t have asked for a better day to climb Mount Adams. The conditions today (6/4) were absolutely perfect!

These 6 miles were waaaay different from the last six I did in LA. This 6-mile climb to the summit packed in 6,700 feet of elevation and took 6 hours 45 minutes (one-way).

Spent the weekend in California for a wedding and managed to squeeze in a quick hike, L.A.-style.

After reaching Mount Lee behind the Hollywood Sign, I couldn`t resist tagging two other peaks along the Aileen Getty Ridge Trail: Cahuenga Peak, the highest point in Griffith Park, and Burbank Peak, home to the famous Wisdom Tree.

The hike came in at 6 miles with just 1,000 feet of elevation gain and took only 2 hours.

Still chasing snow! Took my brother-in-law on his first-ever mountaineering experience. We went up Temple Couloir, over to Deseret Peak, and then slid down West Twin Couloir. Hard to beat spring days like this.

This was my 6th summit of Deseret Peak.

One of my favorite things to do between ski season and hiking season: kicking steps up a steep slope toward some snow-capped summit!

Another moderate day of mountaineering up the north slope of Mt. Superior, known as Cardiac Bowl. I`ve only been to this peak once before, from the typical summer trail, so it was way fun to get there from this direction.

With such good coverage and a big storm rolling in, I think Alta should stay open for at least another week!

It`s been a minute since I`ve had anything other than ski boots or hockey skates on my feet this winter. Gotta switch gears before the mountaineering season melts away here in Utah!

On this day last year—February 18—my team and I reached the summit of Aconcagua, the tallest peak in Argentina and the highest mountain in the Western Hemisphere at 22,837 feet.

I’ve enjoyed looking back on that expedition by rereading my day-by-day trip report from our climb.

👉 Link in bio: an 18-part guide covering the entire climb, plus pre-trip planning tips and post-expedition things to see and do around Mendoza.

Whether this is your first high-altitude objective or you’re adding Aconcagua to your mountaineering résumé, the guide will help you see why I chose the 360° Traverse, how to plan for your expedition, and what to expect each day on the mountain.

Winter is my favorite season, and cold weather camping is one of my favorite winter activities.
