- 2**Drive to Argentine Side:** After clearing Chilean customs, drive approximately 1 km (less than a mile) to the Argentine border post.

- Have pens handy to fill out any forms.
- Declare all food items honestly or dispose of them to avoid fines.

Wait Times
Peak Season
During the peak summer months (December to February), wait times can range from 1 to 2 hours, especially during mid-day.
Off-Season
In the off-season, wait times are generally minimal, often less than 30-60 minutes.
Best Time to Cross
To minimize wait times, aim to cross early in the morning (shortly after opening) or late in the afternoon, avoiding midday rushes.
Car Rental Considerations
Crossing international borders with a rental car requires specific authorization from the rental company. This 'permiso de salida' or 'autorización para cruzar la frontera' is mandatory and must be obtained well in advance, often incurring an additional fee. It includes notarized letters, vehicle registration copies, and proof of cross-border insurance. Most major rental agencies in Chile (like Avis, Hertz, Europcar) can arrange this, but it typically takes several days to process, so factor this into your planning. Without this explicit authorization, you will be denied entry into Argentina, making it critical to confirm this requirement and obtain all necessary paperwork from your rental provider before beginning your journey.
Road Conditions
The road conditions approaching Paso Coyhaique (Río Encuentro Alto) are characterized by gravel on both sides. From Coyhaique, Chile, Ruta 240 is a well-maintained gravel road but can be dusty in summer and slippery or muddy in wet conditions. While generally manageable for 2WD vehicles, higher clearance is beneficial, especially if traveling during less favorable weather. From Río Mayo, Argentina, RP 20 is also a gravel road, similarly requiring caution. Both routes are scenic but remote, with limited services. Always check local road conditions and weather forecasts before setting out, particularly in winter when snow and ice can make driving challenging and potentially lead to temporary closures. Drive defensively and be aware of wildlife.
