Visa for bArzil at iguazu

It depends on your nationality. If you are a citizen of a country which needs a visa, then yes you will need a visa to go to the Brazilian side of the falls.

Argentina side prettiest in the park Sheraton spg.com

falls view rooms are awesome personally short stay over there.

Having spent time on both sides of the falls, we agreed that if/when we return, we will again stay on the Argentinian side. If visiting the Brazilian side of the falls is your only reason to be in Brazil, then it wouldn't seem worthwhile to go through the time and expense to obtain a visa. We enjoyed our stay at the Sheraton, because it's the only lodging right outside the entrance to the park. There are wonderful trails/walks on the Argentinian side that bring you "up close and personal" to different areas of the falls. The raft trip into the falls is well worthwhile. While the Sheraton isn't the classiest hotel, having a falls' view really lets you get full enjoyment out of the experience.

We got Visas and spend the better part of a wonderful day in Brazil. We saw the Brazilian side of the Falls, the Bird Park and then had a lovely lunch at the Cataratas Hotel around the pool.

We considered that day to be worth the time and cost of obtaining a Visa, and friends of ours have felt the same.

We also chose to stay in the town of Puerto de Iguazu for our two nights. If we were there for only one night, then the convenience of the Sheraton would have been our choice: in the town we enjoyed walking around and have good restaurants to dine in. Just another opinion for you to consider.

We did the crossing twice by bus in 2008 once to see the falls and once to do some shopping in Foz. As UK citizens we did't require a visa. On the bus the driver told all the passengers that it was not necessary to go through immigration if we were just there for the day so the majority of passengers (inc. Americans and Australians) just stayed on the bus and went straight through. We saw the same people later that day and none seemed to have a problem. No one even asked to see our passport. On the 2nd trip we decided to hop off the bus and go through immigration just to get a Brazilian stamp in our passports - a quick and painless process. Whether or not this is strictly legal I do not know - probably best to ask at your Hostal in Puerto Iguazu, many of whom will run package trips and should be able to advise on current practice.

A trip to the Brazilian side is definitely worth it as it provides a completely different perspective - much more panoramic than the argenine side which is mpore about getting up close.

No, Crellston, it is not 'strictly legal' and the consequence, should someone from a Visa-required country who did not obtain a Visa be stopped - in or exiting Brazil without it - could be quite unpleasant or expensive. Even though some do get through just fine by sneaking around the law.

Safer and saner (IMO) to get the Visa and enjoy the view.

Definitely get the visa if you intend to cross the border. They used to be more relaxed about it and often just waved known taxis with their passengers through as long as they were only crossing for a short while. This is no longer the case.
