Okavango Delta, Botswana

It seems a bit strange that a river doesn't reach the sea, but this is what happens to the Okavango, the fourth longest river on the African continent. It rises on the Angolan mountains to finish his race in Botswana, flowing into a sea, yes, but a sandy one: the Kalahari desert.

The origin of this phenomenon dates back to the ice age, when the river flowed into the great Makgadikgadi lake (now a desert).

At its mouth, it forms an internal delta, a cradle of incredible biodiversity considered one of the best preserved natural areas where huge quantities of animals can be found, of practically all the species of the African continent.

Asian Monsoon

Often travellers have many doubts about the best seasons to visit Southeast Asia .... let's clarify.

The Monsoon is a seasonal wind accompanied by changes in atmospheric circulation and precipitation due to the heating of land and sea.

On earth, there are many monsoon areas: the Gulf of Guinea, the Gulf of Mexico, Venezuela, Australia, Somalia, Spain, Portugal and northern Russia, but the area with the heaviest monsoon is Southeast Asia, due to the huge continental mass.

summer monsoon

In the summer season, the Asian continent is warmer than the sea, becoming a low-pressure zone and creating fresh and humid winds from the sea, with heavy rainfalls. 

winter monsoon

In the winter season, the Asian continent (high-pressure zone) cools, while the Indian Ocean (low-pressure zone) keeps their waters rather hot, creating dry and cold winds from the continent to the sea.

Best times to visit the Southeast Asian countries:

South: from January to September
Northeast: from March to August
Kashmir areas: from May to September
Himalayan areas: from April to November

Southwest: from December to March

Irta'Ale volcano, Ethiopia

The Irta'Ale (or Erta Ale) volcano, located in the northern area of Ethiopia, Danakil depression, is one of the few existing volcanoes with permanent lava lakes (since the beginning of the 20th century). 

613 meters high, it is one of the most spectacular formations of Northern Africa (like the nearby Danakil depression).

From Addis Abeba and Makelle there are organized tours for tourists: the ascent is about 3 hours, rather easy, but pay attention to the hot temperature.
