I've been in touch with many guides recommended (many from the help of this board) but they're not able to offer us what we want in the short amount of time we're able to spend at the falls (approx. 5 hours).
I have finally found someone who is offering us a package for 5 hours as follows:
Half Day: Cross the Tan***** Neves Bridge with its lovely view of the Iguaçu Canyon en route to the Iguaçu National Park in Argentina. Visit the upper walkways which allow a different perspective and more intimate contact with the falls and adjoining rainforest filled with orchids, bromeliads, birds and other wildlife. The highlight of the trip is a visit to the suspended platform at the very brink of the abysmal Devil´s Throat- largest of the waterfalls. This trip shows you the highlights of the Argentine side.
Duration: 5 hours (they will also be picking us up/delivering us back to the IGR Airport)
Since we've never been there before, does the above include the highlights? We were hoping to at least get a peek at the Brazilian side as well (we have Visas) but this guide is indicating that we don't have enough time. I'm kind of disappointed to not be able to see both sides. Has anyone else ever done both sides under a short time frame as we have? Our other option would be to wait until we check into our hotel (Sheraton) and hire someone through the hotel once we arrive. We stay overnight at the Sheraton but fly out the following morning.
Thanks again for all the great advice I've received here!
