Iguazu Falls: how it works in Brazil — first-hand

Uber payments can be cash-based, but be aware of potential fare adjustments or outstanding charges. In Rio Airport, 99 pickups are on the 2nd floor, while Uber is a short walk from the exit. 2. SIM Cards: SIM cards can be purchased without a CPF at RioSul mall (around 70 BRL), typically at newsstands. 3. Currency Exchange: Airport exchange rates are unfavorable (approx. 3.6 BRL/USD); ATM withdrawals offer better rates (approx. 4.2 BRL/USD with fees). 4. Safety: Areas like Copacabana, Ipanema, and downtown Rio are generally considered safe, even in the evening, provided basic vigilance is maintained and phones are put away promptly after use. 5. Guided Tours: Hiring a guide is recommended for experiences like favela tours or helicopter rides. 6. Food: Explore exotic fruits at São Paulo's Municipal Market. 7. Iguazu Falls: Visit the bird park; a day is sufficient for the Argentinian side, but note the last train schedule to 'Devil's Throat'.

One day is sufficient for each side (Argentinian and Brazilian). Travelers can cross the border into Ciudad del Este, Paraguay, for shopping (electronics, alcohol, perfume). Border crossing is often done without formal passport stamping, but travelers should have ID ready if requested.

Travelers are advised to allocate extra time for their journey and depart earlier. While some report minimal delays due to the construction of an interchange, others describe complete standstill traffic. This situation has been ongoing for about two years.

However, this will be a very fast-paced experience, potentially rushing through attractions. The Bird Park alone can take up to 2.5 hours.

Border queues can be very long (up to 300 meters) for pedestrians, taxis, and buses, potentially causing significant delays.

Approximate costs: Brazilian side entrance ~117 BRL, Argentine side package (entry + boat + snacks) ~100 USD. Best exchange rates for Argentine Pesos are found outside the national park zone.

They are seeking advice on whether to rent a car, its safety, or if using taxis is a better option. Concerns include potential issues at border crossings and the process of changing taxis between countries.

Visitors report positive experiences in mid-June and early August, even with light rain, which did not detract from the experience. Light rain during these months is possible but typically does not significantly impair enjoyment of the falls.
