Courtallam Main Falls, locally known as Peraruvi, is the most celebrated attraction in Courtallam and one of Tamil Nadu's most iconic waterfalls. Fed by the pristine streams of the Western Ghats, the waterfall plunges from a height of nearly 60 metres, creating a refreshing natural shower renowned for its mineral-rich waters. Often referred to as the "Spa of South India," Courtallam attracts visitors seeking relaxation, wellness, and scenic beauty during the famous monsoon season from June to September.

Surrounded by lush forests and mist-covered hills, Main Falls offers an invigorating bathing experience believed by many to have therapeutic benefits due to the herbs absorbed by the mountain streams. The lively atmosphere, nearby local eateries, shopping stalls, and easy accessibility make it an ideal destination for families, couples, photographers, and nature enthusiasts alike.

Whether you're planning a weekend getaway, a wellness retreat, or exploring the many waterfalls of Courtallam, Main Falls remains an unmissable highlight. Early mornings and evenings provide the most pleasant experience, allowing visitors to enjoy the cool mountain breeze and spectacular scenery while witnessing one of South India's most beloved natural wonders.
