Age is not the variable that matters here. Stamina in heat is, and so is the paperwork you do before you leave. Paraguay has no altitude to speak of, no long walk in to its main sights and no great distances between them, which makes it a gentler proposition than most of its neighbors in this region.
What makes it work
- The country is compact. Asuncion to Encarnacion and the mission country is a comfortable day, and once you are there the two inscribed sites are ten kilometers apart.
- The sights are civil rather than strenuous. A mission site, a market town, a lace workshop and a riverfront are all things you can do at your own pace.
- The social day already suits a slower rhythm: early mornings, a long middle of the day out of the sun and late afternoons.
The heat, which is the whole planning problem
From October to March the middle of the day is hot and humid enough to be a genuine health matter rather than a discomfort. Plan every outdoor visit for before eleven or after four, drink more water than thirst suggests, and take the afternoon indoors without feeling you have wasted it. That is what Paraguayans do.
Better still, come in the mild half. May to September gives warm days, cool evenings and comfortable walking weather at the mission sites, and it is the season this cluster recommends for anybody whose trip involves being outdoors for any length of time. See the best time to visit.
Health preparation
- See your doctor well before you travel, and talk through the trip rather than the country. Whether you need a yellow fever vaccine depends on your route in and on where you are going, and the reasoning is set out in the entry requirements guide.
- Bring all prescription medicine in its original labeled packaging, with more than the trip needs and a copy of the prescription.
- Take travel insurance that covers pre existing conditions, medical treatment and repatriation, and read what it excludes. Declare everything.
- Note the emergency medical number, 141, and keep your insurance details reachable without a phone signal.
- Private clinics in Asuncion are the best equipped in the country. In the Chaco the distances mean evacuation cover is a practical matter, not a formality.
Getting around comfortably
- Pre booked taxis and ride hailing, rather than city buses. The cited advice notes that bag snatching and pickpocketing are a problem on public transport and that many foreigners choose taxis.
- A private transfer between the cities and the missions is the easy option and is reasonably priced by regional standards.
- On long distance buses, pay for the better class. The seats recline properly and the journey is a different experience.
Pacing
Two nights minimum in Encarnacion, so the missions are a morning rather than a dash. Three or four in Asuncion, using the early mornings and the evenings. One thing a day in the warm months, two in the cool ones. A country this compact rewards seeing less of it properly, and nothing about Paraguay is improved by hurrying.
For what to bring, see the packing list, and for surfaces and transport in detail the accessibility guide.
