Getting across the Uruguay–Argentina border
The route crosses at about mile 194, at the Gualeguaychú–Fray Bentos bridge, from Río Negro into Entre Ríos. Plan on two checks on each side: immigration for your passport and customs for the car.
| Entering Argentina (U.S. citizens) | No visa needed for visits of 90 days or less. Passport: must be valid when you enter; leave a blank page for the entry and exit stamps. |
|---|---|
| Driving in Argentina | A valid U.S. license usually works; an International Driving Permit is recommended. |
| Entering Uruguay (U.S. citizens) | No visa needed for visits of 90 days or less. Passport: must be valid for 6 months beyond your arrival date. |

| The car, entering Argentina | Argentine customs (ARCA) registers the car's temporary entry.

A rental car needs the rental company's MERCOSUR circulation authorization (ACM), and the company must be registered with Argentine customs. |
| Rental car | Cross only if the rental company authorizes it in writing and gives you the papers for the border; ask before you book. |

How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway markers, and "from the route" distances are straight-line, so the real detour depends on access roads. Stops are chosen from parks, natural sites, museums, historic sites and attractions close to the route: at least one strong stop for each stretch of the drive, then the best-known places nearest the road, up to nine in all. Places that are closed, private or not open to visitors are removed. Place descriptions are written by the Wayro team from official park, museum, tourism and government websites and other published sources. Safety levels and entry rules were checked against the U.S. Department of State on October 10, 2026. Conditions change, so check the linked sources before you travel.
