As a 2010 tour member I have to say that for me it was the trip of a lifetime! As far as the highlights go, too many for me to mention them all in text, if you want the finer details you,d have to ask me in person and I will gladly give them to you as I still remember every sight and sound I experienced.
I’ll just mention a few of the highlights, the tango show in BA (epic), Carnival in Rio spectacular to witness and an amazing adrenalin rush to participate in, Sugar Loaf amazing views point your camera in any direction and still get a great picture, Christ the redeemer, the beaches (and those at the beach), Natal the history, dancing Forro with the locals, the dune buggies, Salvador again the history, the boat trip to islands, the markets, dancing with the locals, Manaus, change of pace, tree top resort in Amazon, visit to local village, boat rides , piranha fishing, catching alligators, more dancing, Iguacu, the falls one of the wonders of the world.
I will leave it there, I have only touched the surface and have left out so much, but one more thing I have to mention is Tarcisio, the best tour guide you could ever wish for, always in control, so patient, always does his utmost to ensure every one has the best trip possible and that after the trip you are left with a lasting impression of the true Brasil.
