This is the day the trip changes register entirely. After weeks of long, largely flat transit across the Argentine steppe, the pampas of Tierra del Fuego, and the Magallanic coast, Torres del Paine announces itself as something different — a massif thrust sideways out of the Andes rather than aligned with it, geologically independent, visually unprecedented. The day begins with a prehistoric detour and ends beneath granite towers that have been eroding for roughly twelve million years.
The Drive
Departure from Puerto Natales is at 8:00 am, with a quick fuel stop at the Petrobras station before leaving town — there is no petrol inside the park, and the next opportunity would be many kilometres away. The route follows Route Y-290, a gravel road also known locally as the Lago Porteño road, well-graded for most of its length, passing through open Patagonian steppe as the low hills gather and the first peaks of the Cordillera del Paine appear on the horizon. The Monumento Natural Cueva del Milodón comes roughly 24 kilometres out, before the park boundary. From there the road continues another 56 kilometres to the Guardería Serrano checkpoint, where entry permits are verified and the internal park road begins.
