The Argentine side in brief
The Argentine side of Iguazu Falls is a national park with several trails, a free train and a visitor center. Puerto Iguazú is the nearest town, about 11 miles (18 km) from the park via national routes 12 and 101.
The park is open every day, including holidays and rainy days, from 8:00 am to 6:00 pm. The last entry is at 4:00 pm. On selected high-season and holiday dates the opening is moved up to 7:00 am. Because the walkways to the Garganta del Diablo have been out of service since August 2026, expect the day to be built around the other trails. This is an independent guide, not the park's own website.

The Ecological Jungle Train
The train is included in the park entry. Collect a separate free train ticket at the distribution points in the park. It serves three stations: Central, Cataratas and Garganta. The first train leaves at about 8:30 am, and the last departure from Central is at 3:30 pm. Trains run every 20 minutes at first, then about every 30 minutes, and about every 15 minutes in high season.
The operator describes the locomotives as electric or powered by liquefied gas, so do not expect a fully electric ride. The Garganta station is the stop that depends on the walkway status. Ask at the train station whether it is in service on your day.
Devil's Throat in 2026
The Garganta del Diablo is the walkway to the Devil's Throat. It is 2,200 m (1.4 mi) there and back and is wheelchair accessible. In August 2026 the Argentine walkways were taken apart as a precaution because of higher river flow. On September 17, 2026 the park service said the other main trails remain open and gave no reopening date.
Do not plan a day around the walkway until you have confirmed it is open. The full story, with access notes, is on the Devil's Throat page.
Tickets, fees and practical notes
Prices in Argentine pesos, from the tariff valid from June 1, 2026.
Entry
Foreign adults pay 60,000 ARS. The Argentine national rate is 25,000 ARS, province residents pay 8,000 ARS, and the 15,000 ARS student rate needs an Argentine ID and proof of study at an Argentine school. Foreign students do not get a general discount. Children are exempt, with the age limit listed as 0 to 6 in the tariff. The operator words it as under 6, so check before you buy for a 6-year-old.
Second visit
A 50 percent discount applies to a second visit within 72 hours of the first entry, online or at the entrance. That works out to roughly 30,000 ARS, a figure calculated from the 50 percent rule, not a listed price.
Payment and parking
Cash, Visa and Mastercard are accepted. A car costs 12,500 ARS a day, a motorcycle 6,250 ARS and a minibus 18,750 ARS. Bicycles must stay at the parking lot.
Wildlife
Do not touch or feed the animals, and use only the open walkways.
Isla San Martín
General tourism pages still list a crossing to the island. Ask at the visitor center before you plan on it, and do not build your day around it.
The tickets page compares the Argentine and Brazilian prices side by side, and the Puerto Iguazú page covers the base town.
Evening walks and a second day
Options if one day is not enough.
The operator publishes Full Moon and Sunset programs at 95,000 ARS for adults and 47,500 ARS for children aged 6 to 12, free up to 5, with limited places. Ask whether your date runs while the Devil's Throat walkways are out. With the 72-hour discount, a second day in the park costs about half the entry price. The tours page compares the paid extras, and the boat tour guide explains the ride under the falls.
