The peaks are made of a rock called limestone. Limestone is softer than granite and water can slowly dissolve it, cutting deep channels and leaving behind sharp ridges and towers. Over time, rainwater carved the Sindou Peaks into the amazing spiky shapes you see today.
Walking through the peaks feels like exploring a maze. The paths twist between walls of rock that rise high above your head, and you sometimes come out into a sunny clearing before the next rocky 'corridor' begins. The Senoufo people, who have lived in this area for a very long time, consider the peaks a special place.
Many different birds nest in the crevices of the rocky spires, and small trees and bushes grow from ledges where a little soil has collected. At sunrise and sunset, the limestone glows orange and pink, and photographers travel from all over the world to capture those colours.
The Sindou Peaks are one of Burkina Faso's most visited natural attractions. Local guides lead visitors through the narrow passages and share stories about how the rocks got their shapes. Some spires even have names based on what they are thought to look like — an elephant's head, a woman carrying a pot, and more.
