We did a 2 day tour with 2 diffferent companies, not by choice. We had booked through one company pre-covid for 1.5 days, the half day on the Brazilian side, the full day on the Argentine side. But by the time we were ready to go after Covid, the price had changed so much that we opted to go with someone else for the Argentine side. And that guide, Ana Kluck, was amazing. A guide is not essential but we thought was worthwhile, especially with border crossings and that insider knowledge that makes everything run more smoothly and stress-free. Ana is available through TourHQ.

estacionamento existe, porém quanto a segurança não posso afirmar.

Hola, conviene la tarjeta, pero lleva algunos billetes desde acá, no compres allá porque te lo cobran mucho mucho más al real. Suerte y a disfrutar

Hola, Griselda. Estamos abiertos todos los días del año. Hasta fin de mes, el 31 de enero, el parque seguirá abierto una hora antes, de 8 a 16 horas.
