Areguá: ceramics, lakefront and Cerro Koi
SENATUR places Areguá 28 km from Asunción and describes a ceramics fair in the center and a lakeside promenade on Lake Ypacaraí. You can start at the stalls and continue to the water. The protected Koi and Chororî hills add a geological stop in the district. Their listing gives conflicting opening hours, so confirm access before adding the site to your route.
San Bernardino: lakefront and Casona Büttner
SENATUR places San Bernardino 50 km from Asunción on Lake Ypacaraí. At Casona Büttner on the Nuestra Señora de la Asunción pedestrian street, the visitor center provides information on local routes and activities; its listing says entry is free. You can then walk along the lakefront. Check the center's opening and the promenade's conditions for your travel day.
Yaguarón: Franciscan church and hill
According to SENATUR, San Buenaventura church preserves carved woodwork associated with Franciscan Guaraní art. For a walk, its Cerro Yaguarón listing describes a climbing trail with stone steps, an oratory and views from above; it advises carrying water and taking breaks. Confirm church hours and trail conditions before leaving.
Budget with prices you can confirm
Casona Büttner lists free entry. The pages we checked provide no current, comparable price for transport, the church, the hill or the other stops. Add your return journey, any confirmed admission and food before choosing a trip. A package tour's price would not represent the cost of visiting independently.
Pick a day and check the route
Allow a day for each destination if you want to see more than one stop without a tight schedule. Check your route, transport and return service for that date; we have not measured travel times. In rainy weather or before climbing the hill, check access conditions too. A visit to San Bernardino can also help you assess the city before a longer stay.
