1. Apply for Your Visa Early: There is no visa exemption or visa on arrival; start your application at least one month in advance.
2. Language Preparation: Spanish and Guaraní are both official languages, and English is not widely spoken—bring an offline translation tool.
3. Sun Protection and Hydration: Subtropical UV rays are strong; avoid prolonged outdoor activities in the afternoon during summer.
4. Cash Is King: Markets, buses, and taxis only accept cash; always carry small denominations of Paraguayan guaraní.
5. Double-Check the Amount: Prices often omit the last three zeros—always confirm before paying.
6. Drink Safe Water: Tap water is not safe to drink; buy bottled water instead.
7. Watch Your Belongings: The tri-border area and bus terminals are crowded and can be risky—keep your phone and wallet secure.
8. Respect the Sharing Culture: Tereré and mate are social drinks; simply acknowledge the offer if invited to share.
9. Book Accommodation Early: Lodging can be tight in Encarnación during Carnival and long holidays.
10. Emergency Numbers: Police: 911, Ambulance: 141, Fire: 132.

Additional Notes

Travel in Paraguay moves at a slower pace, and public transport and English services are limited. It’s wise to build flexibility into your itinerary and avoid overpacking each day. If you plan to visit Iguazu Falls, check in advance whether you need a Brazilian or Argentine visa. When traveling to the Chaco region, go with a driver or tour operator familiar with local road conditions, and carry plenty of water and mosquito repellent.

Overall, Paraguay is great for travelers who enjoy culture and slow travel. Prices are friendly, and the culture is unique—but you’ll also need patience and good preparation. Carry a copy of your passport, keep the original separate from your cash, and check local holidays before you go to avoid closed attractions or banks. If driving into the Chaco, travel with others, stay in touch, and inform your accommodation of your daily plans.
