Arrival information

IMPA is located near the Botanical Gardens in the city of Rio de Janeiro, Brazil.

The address is:

Instituto Nacional de Matemática Pura e Aplicada – IMPA

Estrada Dona Castorina, 110
Jardim Botânico
22460-320 Rio de Janeiro, RJ – Brasil
Tel: (55) (21) 2529.5000
Fax: (55) (21) 2512.4115 / 2512.4112

Leaving the airport

On leaving the airport we suggest that you take a taxi. The yellow cabs are less expensive than
the special red or blue ones, as these have special booths located inside the airport facilities.
The current fares are around R$ 50,00 to R$ 60,00,
respectively, for a trip of about 30 minutes. There are also air-conditioned
buses leaving from the blue sector, terminal 1 and 2, running from the airport to the Novo Rio Bus Station,
Copacabana, Ipanema and Leblon.

Money Exchange

The Brazilian currency is called the Real (R$). Consult
for its current value. You can exchange foreign currencies at the
airport either before or after going through customs. If you plan to
exchange your money back later, you should keep the receipts. Money exchange
is also possible in many (but not all) bank branches and travel agencies. We
recommend that visitors bring along US dollars, as other currency may not be
as easy to exchange. Major credit cards (VISA, MasterCard, American Express,
etc) are usually accepted.


Short-term visitors are often lodged at the Rio Flat Apart Hotel, which
has a nice location in the Leblon district. Rooms for one or two persons
cost R$ 84, including breakfast and taxes (as of 5/21/99).

Renting an apartment may be more convenient for those staying longer. The Department
for Scientific Activities
, located in room 208 (phone: 55-21-25295277), will do its best to help you with accommodations.

Buses and Cabs

There are two bus lines running near the Institute:
line 409 (Tijuca – Jardim Botânico), line 125 (Central – Jardim Botânico).
Pay as you enter, using the rear door to get on
and the front door to get off the bus. The current bus fare is R$ 1,30 and the maximum change
given is for a R$ 5,00 bill.

Should you need a taxi, you may call one of the following cab companies:

JB Taxi (normal)
