Known for its Tibetan monasteries, breathtaking landscapes, pristine villages, and exhilarating off-roading adventures, Spiti Valley offers a distinct charm throughout the year. Whether blanketed in snow or lush greenery, this region possesses a unique, enchanting allure. Recently, Spiti Valley received further accolades as it was announced as India’s first cold desert biosphere reserve by the United Nations Educational, Scientific and Cultural Organization (UNESCO). This recognition was announced during the 37th International Coordinating Council (MAB-ICC) meeting held in Hangzhou, China, from September 26-28, 2025.
The Spiti Cold Desert Biosphere Reserve now joins a global network of 26 new biosphere reserves recognized across 21 nations, a move that is expected to enhance trade and tourism in this high-altitude Himalayan locale.

As mentioned on UNESCO’s official website, 2025 marked the establishment of the first biosphere reserves for six countries, including Angola, Djibouti, Equatorial Guinea, Iceland, Oman, and Tajikistan. Additionally, São Tomé and Príncipe has the distinction of being the first country to have its entire land area designated as a biosphere reserve.
And with this, India now boasts a total of 13 biosphere reserves within UNESCO’s World Network of Biosphere Reserves (WNBR).
What Is So Special About Spiti Valley
The Reserve is divided into three areas: a core zone of 2,665 square kilometers, a buffer zone of 3,977 square kilometers, and a transition zone of 1,128 square kilometers.
