A regular cab ride from the airport to IMPA will cost up to R$ 150,00 – 180,00. These are yellow cabs and run on a meter.
At the airport other drivers will start to harass you as soon as you leave the inner area. Taxi cars are either yellow or white (or sometimes black) and will be lined up outside the terminal. Few drivers speak English, so you should have ready the name of your destination.
IMPA’s address is Estrada Dona Castorina 110, Rio de Janeiro, RJ. Most drivers will not know IMPA nor this address. If you don’t speak Portuguese you can print and show the driver the following info:
“Vou para o IMPA (Instituto de Matemática) no Horto, perto do ponto final da linha 409. O endereço é Estrada Dona Castorina 110. Para chegar lá: subir a Rua Pacheco Leão como se fosse para a Vista Chinesa.”
