Thalaiyar Falls has been a prominent natural landmark in the region for centuries. Its name, 'Rat Tail Falls,' comes from its thin, long appearance as it descends the cliff face. Historically, the area surrounding the falls has been inhabited by indigenous communities. While the falls themselves have remained largely untouched, the surrounding areas have seen development related to tourism, including viewpoints and trekking routes. The ecological significance of the falls and surrounding forests has led to conservation efforts to preserve its pristine beauty.
