Don’t confuse this dull town with the jaw-dropping national park of the same name or the glacier near El Calafate – the only tourist attraction here is cruising the strip on Saturday night. A brief stopover en route to the more inviting Andean oasis of Los Antiguos, Perito Moreno does have a good range of services for a town on RN40, though area mining means hotels are often booked. Attractions Cueva de las Manos and Parque Nacional Perito Moreno are not far off.
The town’s glory came in 1898, when explorer Perito Moreno challenged Chile’s border definition of ‘divortum aquarum continental’ (which claimed the headwaters of Pacific-flowing rivers as Chilean territory) by rerouting the Río Fénix, which flows through town, to Atlantic-bound Río Deseado. The river and the area remained Argentine, and the town took his name. The main drag, San Martín, leads north to RP 43 and south to RN 40; it’s 128km south to Bajo Caracoles and 135km north of Río Mayo.
