Portal San Antonio: the most accessible Iberá in every sense
San Antonio is the portal usually recommended for a first visit to the Iberá, and there are several reasons for that. Access is along RN 5 to San Miguel and then 16 km of well-maintained gravel: any car can make it, even in moderate rain. The Complejo Turístico Aventura Iberá has a canteen with capacity for 100 to 150 people, a camping area with covered BBQ areas and showers, and an interpretation centre. The Jopará providers' association keeps an up-to-date register of local guides that can be checked before arriving. It is the most logistically organised portal after Carlos Pellegrini.
What sets it apart from Pellegrini is scale: San Antonio receives fewer visitors, the groups on excursions are smaller, and the experience is more intimate. The portal is especially valued for birdwatching: the Strange-tailed Tyrant, the Saffron-cowled Blackbird, the Black-and-white Monjita and the capuchino corona gris are frequent records in the area. Local guides know the best spots to photograph these threatened birds, which few places in the country let you see so easily.
The portal also has an astrotourism area over the Estero Bola, with almost no light pollution. The guided night outings combine telescopes with stories in Guaraní about the constellations. The town of Loreto, 16 km away, has dining, quality lodging such as Estancia San Juan Poriahú, and attractions of its own: the Nuestra Señora de Loreto parish church, the municipal bathing spot and the mural circuit.
How to organise your visit to Portal San Antonio
The essential step before arriving is to contact the Loreto Tourist Information Office, or the Jopará association, to get the contacts of the providers active that season. The portal's guides have to be booked ahead: there is no turn-up-and-go excursion system as in Carlos Pellegrini. Once that is arranged the logistics are simple. Accommodation in Loreto or at the establishments inside the portal is affordable, and the recommended length of visit is two to three nights.
