Paso Mamuil Malal (Tromen) Border Crossing
Experience a breathtaking Patagonian border crossing at Paso Mamuil Malal (Tromen), nestled between the majestic Lanín and Villarrica volcanoes. This route offers unparalleled scenic beauty, leading adventurers from the serene landscapes of Argentina to the vibrant Pucón region of Chile. While the journey is stunning, it traverses a significant stretch of gravel road and is known for its seasonal closure during winter, making proper planning essential for a smooth passage.
Paso Mamuil Malal, also known as Tromen, is a picturesque and vital border crossing connecting Argentina's Neuquén Province with Chile's Araucanía Region. This high-altitude pass (approximately 1,200 meters or 3,900 feet above sea level) is renowned for its stunning panoramic views of the Lanín and Villarrica volcanoes, offering travelers a truly immersive Patagonian experience. Unlike some more heavily transited crossings, Mamuil Malal offers a more rustic adventure due to its gravel road conditions and seasonal accessibility. It serves as a key route for those wishing to travel between San Martín de los Andes and Pucón, providing a direct, albeit adventurous, link through the Andean Cordillera. Travelers should prepare for changing weather, potential delays, and ensure all necessary documentation is in order, especially if driving a rental vehicle.

Car Rental Considerations
Renting a car in one country and crossing into another requires specific permissions and documentation from the rental company. It is absolutely crucial to arrange this in advance, usually at least 7-10 days prior to your pick-up date. Most major rental agencies (Hertz, Avis, Europcar) offer cross-border permits for an additional fee, which includes necessary paperwork like a notarized authorization letter and international insurance. Confirm that the rental agreement allows travel on gravel roads like RP62 and Ruta 199, as some policies might void coverage for off-pavement driving. Failure to secure the correct documentation will result in being denied entry at the border, potentially spoiling your travel plans and incurring significant costs.
Road Conditions
Approaching from Argentina, Route Provincial 62 is predominantly a well-maintained gravel road that winds through stunning Patagonian forests and volcanic landscapes, leading directly to the border post. While generally navigable for most vehicles, higher clearance vehicles are recommended for comfort and safety. From the Chilean side, Ruta 199 is also primarily a gravel road for a significant portion, particularly as it ascends towards the border. It can be rougher in sections and may feature washboards or potholes, especially after heavy rains. The pass itself is at an elevation of 1,200 meters, so expect winding roads and be prepared for potential changes in weather, even in summer. Always drive with caution, especially on curves and when encountering other vehicles.
