Cirque Rouge is a stunning natural landmark located in the southern part of Madagascar, near the city of Tuléar. It is a vast canyon, characterized by its unique red soil and rock formations, which give it its name - "red circus" in French. The area is also known as Andronono and is located within the Andohahela National Park, which is one of the largest protected areas in Madagascar.

The red soil and rock formations of the Cirque Rouge were formed over millions of years, as a result of weathering and erosion caused by wind and water. The canyon is about 10 kilometers long and 5 kilometers wide, and its walls rise up to 200 meters high in some places. The red colors of the soil and rocks are particularly striking during sunset, when the light creates a dramatic effect.

Cirque Rouge is a popular destination for visitors to Madagascar, especially for those interested in hiking and nature photography. There are several trails that lead through the canyon, offering stunning views of the landscape and its unique flora and fauna. Visitors can also explore nearby villages and meet the local communities, who are known for their traditional handicrafts and unique way of life.
