About Sierra Sur Biosphere Reserve

The Sierra Sur Biosphere Reserve in Oaxaca, Mexico, is a biologically rich mountainous region renowned for its diverse ecosystems, vibrant indigenous cultures, and extensive opportunities for hiking, wildlife viewing, and cultural exploration.

Wilderness Landscape & Natural Heritage

Located in the Sierra Sur mountain range of southern Oaxaca, Mexico, the Sierra Sur Biosphere Reserve encompasses expansive montane forests, cloud forests, pine-oak woodlands, and high-altitude grasslands. Established to protect the area's extensive biodiversity and cultural heritage, the reserve forms a critical corridor linking various ecosystems that support numerous endemic and endangered species. The region is home to indigenous Zapotec and Mixtec communities who have inhabited and sustainably managed these lands for centuries, contributing to the rich cultural tapestry visitors can experience. Outdoor enthusiasts are drawn to the Sierra Sur for its remote trails winding through dense forests, opportunities for birdwatching (notably spotting species like the Ocellated Turkey and the Resplendent Quetzal), and visits to traditional villages showcasing local crafts and cuisine. The topography is rugged with deep canyons and steep slopes, offering challenging trekking routes as well as serene natural settings. Key landmarks include the Cerro Chicahuaxtla, a sacred mountain, and numerous viewpoints providing sweeping vistas over Oaxaca’s valleys. The reserve's isolation preserves a pristine environment appealing to backpackers and nature photographers. Visitor infrastructure is minimal but includes community-run eco-tourism initiatives emphasizing cultural immersion and environmental education. The biosphere’s conservation goals focus on maintaining habitat connectivity and supporting local livelihoods through sustainable tourism and resource management.
