Sessa Orchid Sanctuary is a 100 km2 protected area of India in the Himalayan foothills in Bhalukpong Forest Division of West Kameng District, Arunachal Pradesh.

The department of Environment & Forests has developed trekking routes for visitors to enjoy the natural habitats of orchids.

There are deep gorges and valleys, high peaks and rugged terrain that are rewarding for nature lovers and adventure tourists.

A nursery includes representative specimens of various orchid species of the sanctuary and a demonstration farm of Cymbidium hybrids for cut-flower production.

[8][9] The Critical Ecosystem Partnership Fund (CEPF), a consortium of major international and regional organizations, has identified the Eastern Himalayan region around Arunachal Pradesh (Nepal, Bhutan and all of North-East India) as a critical global biodiversity rich area deserving of conservation focus.

They identified the North-Bank Landscape (i.e. north bank of Brahmaputra, extending up the Eaglenest and Sessa slopes) and the Tawang region as worthy of particular focus.
