Agaya Gangai, meaning 'Ganges from the sky', is one of the principal waterfalls of Kolli Hills, dropping down a rock face in the Eastern Ghats. A long stairway cut into the hillside leads down through forest to viewing points near the base, though the descent and climb back up require reasonable fitness. The falls are most impressive during and after the monsoon, when the flow is strongest. Agaya Gangai Falls sits at an elevation of 1197 m and is typically explored in about half day. The most favourable months to visit are February, March, June, and July, when conditions are best suited for sightseeing. Nearby points of interest include Agaya Gangai Viewpoint, The Natural Rock Pool, and The 1,200-Step Stone Stairway. Other notable highlights include 1,200 ancient stone steps through dense forest, cool mist from the 150-foot vertical cascade, and natural pool at base for a refreshing dip. It falls within Namakkal district and Tamil Nadu, India.

The trek involves descending about 1,200 steep, uneven stone steps, which takes roughly 45 minutes to an hour down, and the climb back up is physically demanding. It is not recommended for those with knee problems, heart conditions, or low stamina; senior travellers should assess their fitness carefully and consider using a local guide for support.
The ideal time is between October and March, when the weather is cooler and the water flow is moderate, making the trek and the waterfall experience pleasant. Avoid the monsoon months (June to September) as the steps become slippery and the water flow can be dangerously strong, and summer (April to May) is very hot and exhausting for the climb.
Swimming is not allowed in the main pool directly under the waterfall due to strong currents and slippery rocks, but there is a shallow, safer bathing area nearby where you can take a dip. Always follow local guidelines, wear non-slip footwear, and avoid bathing after heavy rain when water levels rise suddenly.
The falls are about 12–15 km from the main Kolli Hills town (Semmedu), and you can drive or take a local jeep to the dedicated parking area at the trek starting point. Parking is available for cars and two-wheelers for a small fee, but on weekends it fills up early, so arrive before 9 AM to avoid crowds and ensure a spot.
At the top near the parking area, you will find a few small tea stalls and shops selling snacks and water, but there are no proper restaurants or restrooms along the trek or at the falls. Carry your own water and light snacks, and note that the nearest medical facility is in the main Kolli Hills town, about 20–30 minutes drive away, so carry any essential medicines.
