Coming from Brazil

Coming from Brazil is the simplest entry of all. The border town is Chuy — Chuí on the Brazilian side, the same place spelled two ways — and the frontier is its main avenue: you ride across it. The immigration post sits out on the highway past the last houses, so you stop there for your stamp and carry on.

From Chuy the road south is Route 9, which has for years been the way touring cyclists first thread into the country, down through the wide ranching country and lagoons of Rocha. Where the land meets the sea, the smaller Route 10 runs nearer the coast, past a string of small Atlantic towns — slower, quieter, and for many riders the better way to take the first days.

If you'd rather skip that opening stretch, the coach comes down from Porto Alegre — and, in season, Florianópolis — crossing at the same Chuy post. Count on roughly twelve hours, and the same rule as everywhere on these routes: call ahead about the bike, because no company publishes a policy.

At the border the formalities are light. Uruguayan customs treats a personal bicycle as sports equipment, nothing to declare. If you've come through Argentina earlier in the trip, the contrast is sharp — here it's just a street, a stamp, and the road opening south.
