Horizons Unlimited - The HUBB - Seeking Suggestions (mostly Brazil, Paraguay, and Argentina)

(Cross-posted on the South America Forum)

Hi HU Riders!  

Forgive this long and detailed post. I’m seeking suggestions from you.

First, I have been mining the Internet and first want to share two resources for identifying places to see when traveling:

https://www.atlasobscura.com/ - quirky and unusual spots to visit
https://new.horizonsunlimited.com/destinations - Horizons Unlimited own source of cool places to see. Do visit this section and add your own destinations!  

I will be traveling in South America for several months starting in late July 2023 and I am looking for cool places to visit, principally in Brazil, Paraguay, and Argentina. The basic clockwise direction starting in Peru and key waypoints have been worked out, but I am open to enhancing the route.

Here is the map of my 2012-2013 trip, showing where I have already been and mostly don’t intend to revisit.

 Here is a long list of places I am planning to visit and places I’ve already seen.

Peru - Planning to Visit
Rainbow Mountain
Moray (series of concentric terraces)
Salineras de Maras (salt springs)
Has anyone been on a jungle between Cusco and Iñapari (the last town before entering Brazil)

Peru - Been there, seen that:
Machu Picchu, Nasca Lines, Lake Titicaca, and nearby Sillustani, the ancient burial ground featuring giant cylindrical funerary towers

Brazil - Plan to Visit
Manaus (via Porto Velho BR-319)
Fordlândia
Serra da Capivara National Park Brasilia
Belo Horizonte and the nearby sculpture center Instituto Inhotim
The Pantanal wetlands (tour operator suggestions anyone?) Bonito (I am intrigued by the crystal clear waters, but the photos on Google Maps make the town look touristy, like Disneyland, true?)

Brazil - Been there, seen that
Parque Nacional dos Lençóis Maranhenses (I highly recommend riders visit the amazing dunes. I could be talked into returning if I end up riding with someone when in northern Brazil…)
Recife, San Salvador, Rio de Janeiro, and Sao Paulo
Iguazú*Falls and Mocona Falls/Salto do Yucumã. I highly recommend visiting these waterfalls!

Paraguay - Plan to Visit
Other than visiting Asunción, I’ve got nuthin’
I will be riding through from southwestern Brazil to northern Argentina and have no idea what is good to see… any suggestions?

Argentina - Planning to Visit Bueno Aires - the city is just too good to pass up even though I’ve been there before. It is also on the way to points south.
Valdes - hoping to see sea lions, penguins and whales…and if the timing is right a killer shark lunching on a seal.
Punta Tombo - Wildlife habitat Ushuaia - The End of the World
Cueva de las Manos - prehistorical cave painting

Argentina - Been there, seen that 
Perito Moreno Glacier
Monte Fitz Roy

Chile - Plan to Visit
Puerto Tranquilo - Marble Cathedral cave
Queulat National Park
Vicente Pérez Rosales National Park
Bahía Inglesa - white sand beach…enough said
Hand of the Desert
Atacama - several points of interest in this amazing desert  

Chile - Been there, seen that Torres del Paine National Park

  Bolivia
I’ll be noodling around the eastern side of the country on my way back to Peru. Any suggestions?

Bolivia - Been there, seen that The Death Road
Salar de Uyuni (did a truck tour of the salar, the mountains, and lakes south)
Sucre, Oruro, La Paz

Thanks in advance!
