Guide To Chuy / Chui
Quick answer: Chuy (Uruguay) / Chui (Brazil) is a small town split down the middle by the border between Brazil and Uruguay, and most travellers use it as a pit stop between the two countries. This guide to Chuy / Chui covers what the border town is like, what to see (a day is enough), where to stay and how to get in and out by bus.
What Is Chuy / Chui Like?
The town’s main street is “Avenida Internacional”. On the Uruguayan side it is called Avenida Brasil, and on the Brazilian side Avenida Uruguay; many other roads in town are also named after countries. The road, barely wide enough for two trucks to pass, is effectively the border between the two countries.
On one side of the street, signs are in Portuguese and shops take Brazilian reais; on the other, shop names are in Spanish and prices are in Uruguayan pesos.
- Brazilian side: Lined with supermarkets.
- Uruguayan side: Duty-free shops selling almost everything at very low prices.

Very interesting to find a town split between two places! I haven’t been to either Brazil or Uruguay but hope to visit soon. Good to know if we have time to spend here that the neighbourhood is beautiful and that we should explore.
It’s always nice to know about these sort of in between places. They often get ignored in guides, but sometimes they are important to have more information on when you need to stop there. Thanks for sharing!
I’ve never been to Brazil or Uruguay, but would love to visit Chui/Chuy and experience the joint culture. Thx for sharing.
I’ve never seen a feature on a town split by a border, Chui/Chuy looks like an interesting place to wander if you’re passing. Would love to see what the view is like from the fort!
