Brazil: Pantanal
Score: 73

This, one of the world's largest wetlands, is a must-visit for wildlife enthusiasts. A vast place with "amazing ecological quality" despite cattle farming and other environmental concerns. A hopeful sign: Tourism projects "benefit locals."

Here is a representative sampling of additional anonymous comments from the panelists. They are not necessarily the views of the National Geographic Society:

"Under great pressure but still one of the most wonderful and most important places to visit."

"One of the few places in the world where I see pristine regions. There are few landowners, and perhaps for this reason the region is mostly protected. I just visited Refúgio Ecológico Caiman, owned by conservationist Roberto Klabin. The place is well preserved and many conservation projects are in place."

"Vast and amazing ecological quality, incipient tourism development that benefits locals, and a good outlook in general, with fewer pressures than the Amazon."

Brazil: Rio de Janeiro Beach Districts
Score: 54

There is no other place like this in the world: beautiful beaches looking up at beautiful hills in the middle of a gritty, spirited, vibrant city. Diminishing the romantic allure: "violence, poverty, and robbery," which increase the need to tackle social problems. The beaches and adjoining neighborhoods are holding up remarkably well.

Here is a representative sampling of additional anonymous comments from the panelists. They are not necessarily the views of the National Geographic Society:

"Rio de Janeiro's Copacabana/Ipanema beaches are developed coastal resorts with amazing beaches. The main issue is crime. The close proximity of the favelas makes a strong contrast with the opulent hotels. The backdrop of the hills and the iconic Sugar Loaf mountain are a major aspect of the appeal."

"High-intensity urban beach destination that maintains its character despite the crowds; in fact the crowds are really part of the attraction. Some water-quality and traffic issues. Despite high density of building, there are many urban oases, outdoor restaurants, and tree-shaded spaces. Beach is kept public and generally well maintained and guarded."

"This area has always been densely built up. While some of the older landmark hotels have been refurbished and a few new ones built, the neighborhoods are still vibrant, pedestrian-friendly, and reflect the wonderful Cariocan esprit and joie de vivre."
