Ecotourism in India began in the late 1980s and gained momentum in the early 2000s. Initiatives like the Thenmala Ecotourism Project in Kerala showcased planned ecotourism destinations integrating state departments, private sectors, and local communities. By 2025, the market size of ecotourism in India was valued at USD 11.09 billion. However, this growth has also led to challenges, including over-commercialisation and ecological degradation.
