It was an excellent tour The group I went with were fun and the guide good. Seeing both sides in one day is definitely doable with this tour.

The guide, Mr. Brhenno, was one of the best: funny, full of historical stories, was always pointing out interesting features and animals, and was flexible to the interests of the group. Seeing both sides of the falls is recommended (personally, I preferred the Brazilian side), and it is so much easier with this efficiently run organization.

This is a brilliant tour. I think it would be impossible to self-guide a one day trip seeing both sides of the falls and taking the optional boat trip under the falls. The guys at Gray Line know how to make the most of the day. And what a day it is - the falls are the most amazing thing any of us have ever seen - we were blown away. I won't post photos as you don't need to - there are thousands online. Look at them and know that basically you will see all of that and more. It's not a cheap day out after the park passes, the boat trip and out of pocket expenses - but it's absolutely worth every penny. Strongly recommended.

Wow...these guys where the best. We had booked this trip a year ago. These last 2 weeks my father in law became less and less mobile. When we got to Foz we started to learn about the work that it takes to go to visit the Water falls. My father in law was not hoing to be able. So these guys last minute changed everything for us. They ended up fibdibg a wheelchair, our tour became private and one of the guides pushed him all the way to the platform in front of the Devil's Throat. He had a lot of fun. We went with the other guide on the trail and it was fascinating! We all met later. The guides get you in front of the lines everywhere. Getting a guide if you are an elderly or have one with you is the way to go. These guys will adapt and make your visit very pleasureble. Things I learned about Foz. Both sides on the Falls is a very , very long day and unless you are young or in very good shape skip and do on 2 days. The Brazilian side is nicer than the Argentinian. You see more beauty. The Brazilisn side you see from the front and in the Argentinian side you will see from above. Also Paraguay, Argentina and Brazil meet so your trip can be much more than just the falls. Plan well, read well before you go and contract these guys for your tour!

Well organised tour with excellent communication. The falls are amazing but this trip allows you to enjoy the whole experience with great organisation that reduces the queues. I would thoroughly recommend it!

Lucas was a great guide! Super friendly and personable. Took us on a day through Iguazú falls getting to do everything we wanted to in the falls. Helicopter ride, boat tour, walking along the falls, bird park, coati and capybara sightings. Great trip from start to finish!

What can I say, its truly amazing wherever you are but the Devils Throat is the best part and we did helicopter, boat trip boat sides and stayed inside the park.

The views were wonderful. Great family outing…I would suggest it to anyone. We had super weather and great company in the others in our tour group!

Amazing views of the falls from both the Argentina and Brazil sides. Our tour guide Henrique was very knowledgeable, accommodating and patient. He truly went the extra mile!!

The views are amazing and the path over the river is great. This is a different view you don't get from the Brazilian side. HOWEVER... the rest of the infrastructure and organization are dated and insufficient. They only accept pesos, it is quite more expensive than the Brazilian size, long queue to pay, crowded and disorganized, the boat rides don't allow under 12 (brazil I went with 7 year old) police stops you "tourists only payments" on YOUR WAY OUT (basically an extortion). Al the vices of Latin American countries in one. Basically: if you're adult on an organized/ guide tour, the views are TOTALLY worth it. If you're a family with young kids (12 or less) brazil is vastly better, except for the unique views of the garganta del Diablo.

What an excellent experience. I was not quite sure what to expect and I was blown away by it all. My recommendation is that you start your journey at the last stop and walk backwards as the last stop is where the best and most powerful falls are. Also if possible start early to avoid the crowds as it does get crowded.

Great way to see both sides of the Iguazú Falls. Host was knowledgeable and spoke good English. Transportation was easy and comfortable.

It was so worthwhile doing both sides of the Iguazu Falls. The tour was well organized and pickup/dropoff was seamless. You get a great perspective to see both sides of the falls on this tour. The guide Mary was absolutely fantastic and extremely helpful. I would 100% recommend this trip!!

This was the perfect way to see both sides of the falls in a single day. Our group was very small (7 people including us to start, 5 to finish) and John made sure we saw it all, helped us find the best spots for photos, stopped for souvenirs and bathroom breaks, and was an excellent photographer himself! Absolutely stunning and a great decision to book this tour. Thank you!

This was a lot of fun and much more than I expected. Our guide Mauricio arrived at our hotel early to take us to the tour. From the visitors center at the dam, we boarded buses that took us to the viewing area. Live music with songs from Paraguay, Argentina, and Brasil started everything, then the illumination show began. Lot's of fun!!! Next time I will do a day visit to the dam to see the operation.
