Trek from Argentina to Chile Across the Andes

This trip visits locations at or above 2500m. At this altitude some people may experience symptoms associated with Altitude Sickness, also known as Acute Mountain Sickness (AMS). Previous experience at high altitude is not necessarily an indicator of future performance. Your guide(s) are trained to mitigate the risks associated with altitude, by carefully managing the rate of ascent and the intensity of the activity, and to provide the appropriate support response should someone feel ill during the trip. Should you experience health issues during your trip you should inform your guide immediately so the proper care can be provided. Owing to the nature of this trip, it is essential that your personal travel insurance policy provides cover up to the maximum altitude visited on this trip as well as emergency medical evacuation by helicopter.

This trip visits locations which can be considered to be remote, where the travel time to the nearest medical facility is likely to be above 12 hours, even with outside assistance. Outside communications in some locations may be limited. An evacuation may require a change of route from the originally planned one and the use of a support vehicle, either privately owned or public transport by land, air or water, to reach a point of medical care. Additional consideration should be given by and to those with pre-existing medical conditions with specific care needs and should be raised with your host before the trip. Those with pre-existing medical conditions should also seek guidance from a health professional prior to travelling. Should you experience health issues during your trip you should inform your guide immediately so the proper care can be provided. All travellers should have suitable and adequate travel insurance in place to provide cover for potential additional costs.

Like crossing any other international border, you will have to pass through immigration and customs in both countries. The difference here is that the neighbouring border offices are located on either side of a huge mountain range!

You'll complete the Argentine formalities on Day 2 - shortly after beginning the trek you’ll arrive to a place called Refugio Portinari, a gateway point to the Andes crossing trails where a small border outpost guarded by the 'National Gendarmerie' border force is located. It is here that you’ll pass through the Argentine customs and passport control. Your trekking guide team will of course be on hand to assist with any help or translation needed.

You’ll step foot on Chilean soil for the first time on Day 7, crossing the border line dividing the country's territories. After finishing the trek there is a short vehicle transfer to the nearest Chilean immigration office (run by ‘Los Carabineros de Chile’) which is a roadside office in the small town of San Gabriel. Here your passport will be checked again, stamped for entry into Chile, and you'll be on your way.

Tips for the guiding team are not included in the trip cost. These are entirely at your discretion but there is an expectation to tip for good service. Your guide will help with advice, however we suggest the below as a guideline per person:

• $5-10 (USD) per day, per guide (or equivalent in Argentine pesos)
• $3-5 (USD) per day for 'muleteer' porters

Of course, you are free to tip more or less, and the amount should be reflective of your perception of service and quality – a tip is not compulsory and should only be given when you receive excellent service.

During the trek, safe drinking water can be sourced directly from mountain streams and rivers. The guiding team will have water purification options should you wish to use them.

If bringing your own filter bottle, then check out our guide to the best water filters.

As this is a linear trek, you won't be returning to Mendoza as part of the trip, so should factor this into your packing. We recommend packing lightly without too many unnecessary items. If you plan to return independently to Mendoza after the trip then you can use the option of leaving excess luggage with the host for collection later on. For this service, they charge USD $20 per person, payable locally in cash.

Yes. Our host works only with well-respected local mule handlers known as 'arrieros' who care for the mules throughout the journey. The welfare of the animals is paramount and taken very seriously by the handlers who make a living working with expedition groups. Pack mules are traditionally used in this part of the world for transporting goods slowly over mountainous terrain, using their robust strength and balance. A weight limit of 60kg per mule is strictly observed, which is well below the weight that mules are typically comfortable carrying.

Sure can! Over 70% of our travellers travel solo, it’s a great way to meet like-minded people.
