Paso fronterizo Entrada Mayer

Entrada Mayer links Villa O’Higgins in Chile’s Aysén region with the route to Gobernador Gregores in Argentina’s Santa Cruz province. On Argentine maps, look for Río Mayer – Ribera Norte. In June 2026, the municipality of O’Higgins announced the crossing had reopened to 4×4 vehicles. On the Argentine side, the Río Carrera has a ford that can become impassable when the water rises. Check whether vehicles can cross and confirm the hours before you set out. The Argentine border page lists a contact number. Checked on 4 November 2026.
