Two to three daily buses from Salta (AR$208, 5½ hours) and the Tren a las Nubes stop here. You can also join a shared remise for AR$225 per person. Ask at the main plaza. Precious little transportation crosses the Paso de Sico to Chile; ask around town for trucks. From San Antonio, a good ripio (gravel) road runs 97km north, skirting the Salinas Grandes to intersect with paved RP 52.
