Lake Ypacaraí has two shores and two towns that are almost never visited together, even though they share the same basin and sit less than an hour apart. On the western shore is Areguá, a town of clay and workshops; on the eastern shore, San Bernardino, the German-Swiss colony of 1881 with its lakefront promenade. This guide treats them as a single one-day cultural route, with the real logistics and without inventing opening hours that change every month.
Before going further, the usual disambiguation: this is San Bernardino, Cordillera Department, Paraguay, about 50 km from Asunción — not the city of the same name in the United States.
Why the two towns work better together
Areguá and San Bernardino are products of the same geographic accident and two different histories. Both face Lake Ypacaraí, both became summer destinations for Asunción over the twentieth century, and both retain an old centre with architecture that is not repeated anywhere else in the metropolitan area.
The difference is the material. Areguá built itself around clay: its identity is ceramics, artisan production and an art scene that gave the town a cultural reputation of its own within Paraguay. San Bernardino built itself around the colony: founded on 24 August 1881 by German and Swiss settlers, it left behind European built heritage of which identifiable pieces still stand in the old centre.
Visiting them separately works. Visiting them on the same day works better, because the comparison is the content — two different ways of having used the same lake. It is also the clearest answer to anyone who assumes Paraguay has nothing to offer beyond the capital.
The real logistics of a one-day combo
Areguá is closer to Asunción than San Bernardino: you reach it on the road out of Luque, a run that in normal conditions takes under an hour. San Bernardino is about 50 km from the capital via PY02 (Ruta 2) and then PY23, at 50 to 70 minutes depending on the hour.
Here is the part that surprises people: no road crosses the lake. To get from one shore to the other you go around the basin, and that means anywhere from 40 minutes to a long hour of driving depending on the route you choose and the condition of the road. It is a perfectly manageable stretch, but it has to be budgeted into the day and checked on a map on the actual day of travel, because secondary road conditions in this area change.
On the tourist train to Areguá: it has run intermittently over the years, with active seasons and suspended ones. Do not build the plan around it without current official confirmation.
One calendar note for this time of year: on Sunday 13 September there were road closures in San Bernardino and on the approaches towards Altos and Nueva Colombia for L'Étape San Bernardino by Tour de France. That date has passed and traffic should be back to normal, but if you are travelling in the days after, confirm that no localised restrictions remain before setting off.
Morning in Areguá: clay, streets and the high view
The way to do Areguá is on foot and without a schedule. The town is laid out on a slope rising from the shore, with cobbled street, old houses and a concentration of ceramic workshops and shops visible straight from the road. From the upper part the lake opens up, and that view is one of the reasons the town became an artists' destination.
What you buy there is locally produced ceramics, ranging from utilitarian pieces to decorative work by named makers. Two honest caveats. First, we do not publish workshop prices or hours, because they vary by address and by season, and many open and close according to footfall. Second, weekends concentrate the activity; on a Tuesday at 15:00 you may find much of the street shut.
Areguá is also associated with strawberries — frutilla — with local production traditionally celebrated between winter and the start of spring. If that angle interests you, confirm the local calendar for the current year, because fair dates are not fixed.

Afternoon in San Bernardino: the colony and the waterfront
Across the lake the register changes completely. San Bernardino has no workshop street; it has a colony centre, with buildings that tell the story of Asunción's elite summering here and of the German-Swiss community that founded the town.
The Hotel del Lago, from 1888, is the centrepiece of that story and the most photographed building in town. Its history runs through periods of splendour, closure and restoration, and its opening status and visiting conditions change — confirm before counting on going inside. Casa Hassler points to Émil Hassler, the Swiss naturalist whose botanical work in Paraguay became an international reference. Casona Büttner belongs to the memory of one of the founding families. All three, plus the street grid of the old centre, can be covered on foot.
The Anfiteatro José Asunción Flores, named for the creator of the guarania, closes the heritage circuit and ties the town to Paraguayan music. The full list of visitable points is organised in the tours and attractions category.
After the centre, the waterfront. Playa Rotonda and the Club Náutico area are the two clearest access points to the water's edge, and in late afternoon the lake gives back the best light of the day. About the water, the necessary warning: Lake Ypacaraí is not reliably safe for swimming. Monitoring by MADES, Paraguay's environmental authority, has indicated in various periods that its waters are not fit for recreational contact, due to cyanobacteria blooms and the pollution load of the watershed. Look, walk, photograph; do not get in without checking the current official status.
Where to eat, and why that sets the order of the day
The combo has two versions, and food is what decides which one suits you.
If you do Areguá in the morning and San Bernardino in the afternoon, you have lunch in Areguá or en route and dinner in San Bernardino, which has the broader food scene of the two — Paraguayan cooking, parrilla, Italian and a few houses of German heritage. This is the recommended version if you want to end the day with a slow dinner and a sunset over the lake. Options are in the restaurants category.
If you do it the other way round — San Bernardino in the morning, Areguá in the afternoon — you gain the colony centre without crowds and an afternoon of workshops, but you lose the eastern-shore sunset, which is the better one. That is the right choice if your priority is buying ceramics unhurried and getting back to Asunción early.
And if the day stretches, there is a third version, the one we recommend most: one night in San Bernardino. The combo stops being a race against the clock and becomes two full half-days. The hotels and guesthouses category has the inventory for that, and the itineraries hub collects other day combinations built for the region.
Frequently asked questions
Can you do Areguá and San Bernardino in the same day? Yes, with an early departure from Asunción. Budget the leg between the two shores: you have to go around the lake, there is no direct crossing.
Which one should be visited first? Areguá in the morning and San Bernardino in the afternoon is the sequence with the better return, because it leaves sunset and dinner on the eastern shore.
Do the Areguá ceramic workshops open every day? There is no single rule: it varies by address and by season, and activity concentrates at weekends. We do not publish hours because they change; confirm ahead if you have a specific workshop in mind.
Are the roads normal after L'Étape on 13 September? The race has passed and traffic should be back to normal, but check for any current local notice before setting off.
Can you swim in Lake Ypacaraí? Not reliably. MADES monitoring has indicated in various periods that the water is not fit for direct contact. Always check the official status before any contact activity.

Do the combo this week: ceramics in the morning, the lake in the afternoon — or the reverse if you need to be back in Asunción early. Leave before 08:00, give the between-shores leg some slack, phone ahead to wherever you plan to eat, and in a single day you will have seen the two ways Paraguay found to inhabit the same lake.
