Cirque Rouge, located near Mahajanga, Boeny, Madagascar, is a stunning natural amphitheater of red sandstone formations shaped by erosion. Accessibility can be challenging, often requiring a 4x4 vehicle, especially during the rainy season (November to March) when some areas may be impassable. While solo exploration is possible for experienced hikers, a guided tour is recommended to navigate the terrain, learn about the geological history, and spot local wildlife. The visit typically lasts 2-4 hours, and costs can vary depending on transportation and guide fees, but expect to spend approximately $20-$50 USD. Remember to bring water, sunscreen, and appropriate hiking shoes.
