After seeing both sides of the park, we preferred the Argentina side because it felt more organized, with plenty of options for exploring, whether by train, shuttle, or on foot. The Brazil side had more of a touristy vibe, but they do offer more boat rides. The observatory deck is close to the falls, and the trails provide amazing views. There are also many cafes and restaurants on-site, and a hotel as well. It can get quite crowded, so be prepared for that. The park opens at 9 am. If you're into hiking or biking, they offer an 18km jungle trail, along with a shorter 3km round-trip trail that takes you to the river.
