Where did you visit for its geographical significance?

Lencois Maranhenses

Hadn't heard of that. Damn. Add it to the list.

Yes, hopefully we all want or do go to places with impressive, interesting, <insert superlative> places, but my interpretation of @Mattg OP was those more specific locations that in themselves may not be the most spectacular but unique because they’re one of kind (as have some examples been listed).

Another one we did years ago (at SYD+1s insistence) was going to the “Meeting of the waters” where the Amazon River and the Rio Negro meet. There were visions of blue water meeting black water….

There is indeed a noticeable colour difference and even a specific point where they meet, but it’s basically light poo coloured water meeting really dark poo coloured watered…. Possibly one of the most underwhelming experiences, but we “Ticked” that one of the list….

Agree. The Lencois is all about the geography and it was definitely worth the effort. Dunes forever and between each beautiful pools. We flew up to Sao Luis just to go here
