San Antonio is a working port city 100 km southwest of Santiago on Chile’s Pacific coast. It’s one of Chile’s busiest cargo ports, a local beach town for Santiaguinos, and a largely overlooked base for expats who want Pacific access without Viña del Mar’s prices or Valparaíso’s tourist crowds. It’s not glamorous, but it’s functional, cheap, and strikingly close to the capital.
Population: ~100,000 | Region: Valparaíso | Getting there: 100 km southwest of Santiago, 1.5 hours by bus

Thevibe
San Antonio is a working city that happens to have beaches. The port dominates the northern part of town; the southern beach areas are more residential and relaxed. The Mercado Municipal is good for fresh seafood — this is a port city, and the fish and shellfish are excellent and cheap. Cartagena, a short drive or bus ride south, has more expat and tourist infrastructure and a nicer beach scene.
In summer (December–March), the coastal area fills with Chilean families from Santiago. The rest of the year it’s quiet — very quiet in some areas. The climate is cool and often foggy, typical of the Chilean Pacific coast.
Whereissanan to Nio
San Antonio sits on the Pacific coast at the mouth of the Maipo River, in the southern part of the Valparaíso region. It’s closer to Santiago than Viña del Mar but far less developed as a tourist or expat destination. The surrounding area includes several beach communities — Cartagena, El Quisco, El Tabo, and Algarrobo — that together form a popular summer coast for Chileans.
Getting there: Regular buses from Santiago’s Alameda terminal, about 1.5 hours. Very cheap (~$5 USD). No commercial airport — use Santiago (SCL).
