Everything went well until after lunch when we were first asked to shift to another guide with a smaller van, but then just after about 15 minutes we were transferred like goods to a third guide with a even smaller van WITHOUT air-con and the driver who also served as a guide but DID NOT SPEAK a single English word! This was totally a nightmare!

Despite no correspondence prior to pick up time in morning had to callViator and emergency no, night before plus a 20 minute late pickup in morning, the trip to the Brazil side of the Falls was worth every . The Dam add on too as we were only ones on that excursion with the group and they gave us our own Taxi driver to take care of us for this part. We didnt get back to accommodation until 6.30 pm but driver handled everything. Great value for money.

I was very disappointed! It is basically a drive-through of a 1 and 1/2 hours. Not enough stops...the stops they had was for 5 minutes. And then there is the stop at the Catamaran harbour!! What a complete and utter waste of time. The whole problem started with the useless Grey Line website that did not explain clearly enough what was going to happen. They also did not give other options. I only discovered at the dam that there are more detailed tours.

Went to Iguazu falls but no Dam visit ,guide said closed,he did not seem to know why, only that it was closed.

This tour wasn't really a tour as such and I'm sure you could spend your money better on a driver or a local bus to take you to the falls. We were the only English speaking tourists and felt as though we missed out on facts and things you would expect in a tour. Don't bother with the dam either.

The falls from this side are exciting. Remember to dress well because you will get wet. The Itaipu dam is very interesting and inpressive mainly for technical people. Other people will find it a bit boring.

Best tour we did whilst in South America. So different from the Argentinian side. Trip to the power station was just mind boggling, so big, just opened your eyes to what man is capable of.
Guides helpful and friendly plus good English.

But don't be surprised by 2 hour wait at the border.

After seeing the Iguassu Falls from the Argentinian side the day before it was still worth to also visit the Brazilian side. We found that the overall views were actually better from the Brazilian side compared to the Argentinian side. This is due to the fact that on the Argentinian side you are basically "in" or "on top" of the falls and from the Brazilian side you can take the better pictures as you are slightly further away. We would not have wanted to miss on or the other side and strongly recommend to visit both sides.

As for the trip to the Argentinian side that we had booked through "viator" as well we did not know in advance that the entrance fee to the falls is not included in the tour price which was somewhat disappointing. But in comparison to the Argentinian side we could pay with a foreign credit card.

Also the visit to the dam was really interesting and impressing.

Between the two parts of the trip we stopped for lunch which was included in the tour price (except for drinks). Although it was a lunch place where only tourist groups are brought to we were surpised how good the food was and how much variety was offered.

Awesome day in Brazil at iguazu Falls and itaipu powerplant. Perfect guide!
