​Vaccination 
No vaccination is mandatory for entry in Brazil, but certain vaccines may be recommended depending on your travel plans. We suggest that you check with your doctor and or travel agency about travel-related vaccinations. Yellow Fever vaccination is not required for visitors staying in Rio de Janeiro, as the city is not considered a risk area.

Visa
Check if a visa is required to enter Brazil, which depends on your citizenship. Although it is not required for citizens of most countries, from April 10, 2025 Brazil requires e-visas from USA, Canadian and Australian citizens, as a reciprocity procedure. To access the e-visa platform kindly visit: www.brazil.vfsevisa.com

A private transfer for up to two people costs BRL 380.00 / US$ 70.00. If you are traveling with more than two people on the same flight, please contact sales@havasbrazil.com.br to arrange for a larger vehicle.
Alternatively, you can use services available directly at the airports and bus station. Here are our recommendations:

GIG – Antonio Carlos Jobim Airport (International and Domestic)

• Uber: There is a dedicated pickup point for Uber passengers on the arrivals level. To find it, exit the arrivals area and turn left.
• Taxi: We recommend using the executive taxi service with a pre-paid voucher. You can purchase these vouchers at the Coopertramo, Coopatur, Transcopass, or Transcootur counters located in the domestic and international arrivals areas. Executive taxis depart from Level 0, Door B, near domestic arrivals.

SDU – Santos Dumont Airport (Domestic Only)

• Uber: The Uber Lounge is located in the Bossa Nova Mall, next to the airport. This is the only authorized pickup location. Exit arrivals, turn left, cross the departure terminal, and follow the signs to the mall to find the lounge.
• Taxi: We recommend using the executive taxi service with a pre-paid voucher. You can purchase these vouchers at the Coopertramo, Coopatur, Transcopass, or Transcootur counters in the arrivals areas. Executive taxis depart from the arrivals area.

Novo Rio Bus Station

• Uber: The official Uber pickup lounge is on Floor G1 of the parking garage, next to the terminal. You'll need to use the walkway that connects the terminal to the garage to get there.
• Taxi: We recommend using the executive taxi service. You can find the counters for special taxi cooperatives in the arrivals hall.

Note: The fare to Barra da Tijuca ranges from US$ 30 to US$ 60, depending on the transport type (Uber or executive taxi), route, vehicle, and time of day.
