The Best of Brazil .

Chapada dos Veadeiros is a big geographical area in the center of Brazil, well known for it's amazing fauna, flora and geological formations. There's a National Park, which has an area with 65,515 hectares with plenty of great landscapes, gorgeous waterfalls and lakes and is sought after by many travelers in search of true contact with nature.

São Jorge is a small village right in front of the National Park's entrance. It lacks infrastrucure like asphalt roads and public ilumination, the intent is to leave the region around the park pretty much as it is, in order not to disturb it's fauna and flora. Even though it might sound uncomfortable for some, that's what makes the small village special. There you really feel you're somewhere mankind hasn't dominated yet, and there you can really experience Chapada.
The Chapada region is also a magnet for mystics attracted by the alleged properties of the its crystal soil and rumored UFO appearances.

Rumour has it that, according to NASA, the Chapada is Earth's brightest point as seen from space. Lying on a quartz crystal bed, it's said to reflect light like a mirror.

Flora and fauna
Cerrado is the predominant kind of vegetation. The trees are low and curved, and the vegetation is usually ground-high. It is similar to the Savana vegetation in Africa.

Cerrado wildlife, including orchids, buritis and many threatened animal species such as the pampa deer, swamp deer, jaguars, guará wolves, rheas, crested seriemas, tapitis (small hare-like rodents), giant armadillos, great anteaters, capybaras, tapirs, red-breasted toucans, king vultures and black vultures.

Climate
Chapada’s climate is tropical, hot and semi-arid. The average annual temperature is around 25ºC (77ºF). The National Park can be visitied year-round. Its rainy season is from December to Februarry and the rest of the year it is mostly sunny and hot. At the height of the dry season (September), the temperature can peak at 40ºC (104ºF).

In the beginning of the year the climate is very humid, and it rains pretty much everyday. It is very dangerous to be close to a waterfall during bad weather, so, avoid visiting the area during those days.

After May, the rain ceases and the climate turns almost desertic. There's a six month period with almost no rain at all and it gets pretty dry and hot, as you can imagine (what makes the waterfalls even better!). In that sense, the best period for visiting is between June and July, because the probability of raining is very low, and the waterfalls still have plenty of water. After that, it is still worth seeing it, but the waterfalls won't be as good because they start running low on water (no, they never get dry).
