The journey to the hills of Western Uganda starts here. And a drive through the Queen Elizabeth National Park comes with large obstacles.

Our interest though is not the giant mammals… but rather the craters. Uganda has more than 70 of them.

"Some of these crater lakes were formed thousands of years due to volcanic activity. They used to be mainly visited by researchers but now tourists have discovered them as major attractions," said Hillary Ayesiga, Kasese, Uganda.

This group hails from Italy and Spain.

"This area is obviously attractive, my group is astonished, and the beauty of the landscape, and all the time I come here I see the faces smiling at this place," said David Palumbo, European tourist.

Some of the rocks and vegetation are unique to this savannah region. Scientists say they're evidence of earth formation from geological activity millions of years ago.

"Although they are extinct volcanoes, they still have a very large ecological value to the ecosystem like they are inhabited by several primate species," said Petra Biira, guide of Uganda Wildlife Authority.

While some craters have become lakes, others are full of trees. The basin-like structures and depressions offer beautiful views.

It's this rare landscape that Uganda is hoping to promote to visitors, an alternative to the wildlife attractions that have sustained the country's tourism sector for so many years.
