🌋 Erra Matti Dibbalu – India’s Red Sand Hills Join UNESCO’s Tentative List
Tucked away along the scenic coastline of Visakhapatnam (Vizag) lies a surreal landscape that looks straight out of Mars — the Erra Matti Dibbalu, meaning “Red Sand Hills”. Recently added to the UNESCO Tentative List of World Natural Heritage Sites, this geological wonder is one of India’s most extraordinary natural formations.
Nicknamed “Vizag’s Grand Canyon”, these fiery red dunes glow beautifully under the sun, offering a mesmerizing contrast against the blue Bay of Bengal.
🏛️ The Ancient Story Behind the Red Sand Hills
The origin of Erra Matti Dibbalu dates back 20,000–50,000 years, formed during the Late Quaternary period by a combination of wind, water, and sea-level changes. The rich red color comes from oxidized iron minerals, giving the dunes their signature hue. British geologist William King first documented these formations in 1886, calling them one of the rarest coastal geomorphic features in India. In 2016, the Geological Survey of India (GSI) declared the site a National Geo-Heritage Monument.
Today, scientists study these dunes to understand ancient monsoon patterns, sea-level rise, and climate change – making it both a natural beauty and a geological treasure.
🌏 UNESCO Tentative List Recognition
In August 2025, Erra Matti Dibbalu officially entered the UNESCO Tentative List under the Natural Heritage category – a vital step toward full World Heritage status. This recognition aims to bring global attention and conservation support to the fragile dunes, which are threatened by unregulated tourism, pollution, and erosion. The Andhra Pradesh government, along with the Geological Survey of India, is now developing stricter protection measures and sustainable tourism plans.
