Bahía Blanca to San Martín de los Andes via Choele Choel

Added on 4 Nov 2026
Logged by @fakir27

Across the dry northern edge of Patagonia, from the port of Bahía Blanca along the Río Negro valley to Choele Choel, over the steppe to Piedra del Águila above the Limay river, and up into the Andean lakes at San Martín de los Andes. In January 1952 Guevara and Granado rode this way on La Poderosa II: Ernesto spent several days in hospital in Choele Choel with a fever, and the pair crashed more than once on the gravel and in the wind before reaching San Martín de los Andes on 31 January.

Trail Profile

General Instructions

About 923 km one way; allow two days. Long stretches of steppe have few towns, so fill up whenever you can, especially between Choele Choel and Piedra del Águila. Strong west winds blow across the road for much of the year, which matters on a motorcycle. Best from October to April.

Best time to go

Oct–Apr

October to April is the best time for Patagonia and the Andes, with mild weather and long days. Winter, from June to August, brings snow to the mountains, but it is a good time for riding around Córdoba and Buenos Aires.
