Start with a hearty South Indian breakfast (idli, dosa, medu vada and filter coffee) at a busy tiffin shop near Thenkasi bus stand — most open from ~6:30am; a good way to fuel up before temple visits and waterfalls.
Visit the historic Kasi Viswanathar (Shiva) Temple in Thenkasi for morning darshan — temple typically opens around 6:00am–12:30pm and again in the evening 4:00pm–8:30pm; important culturally and centrally located.
Short scenic drive from Thenkasi into the Courtallam falls area (15–30 minutes depending on exact stay); you’ll pass tea/coffee stalls and small shops — parking available near main falls.
Explore the main Courtallam waterfalls (popularly called Kutralam) where you can enjoy the cascading falls and natural massage pools — most falls are accessible 6:00am–6:00pm, but check local notices for safety/seasonal closures after heavy rains.
Have lunch at a nearby family-run restaurant known for fresh local Tamil Nadu meals and seafood (try the fish curry, Karuvadu kulambu or a Chettinad-style chicken); most eateries open 11:00am onwards — confirm opening times in low-season.
Walk between the cluster of smaller falls and viewpoints (Five Falls, Tiger Falls area) for photography and quieter pools — falls/access typically open till around 5:00–6:00pm; wear non-slip footwear and follow local safety signs.
Return to Thenkasi for a relaxed stroll through the local market — pick up tea, jaggery-based sweets and small souvenirs; markets are generally active late afternoon.
Enjoy a warm dinner at a clean family restaurant in Thenkasi. Order regional specialties such as mutton curry, vegetable korma, rice and local chutneys — many restaurants are open until 9:30–10:00pm.
Have a quick early breakfast or request a packed tiffin from your hotel (idli, upma or pongal plus tea) so you can leave early for the Manimuthar Dam & falls area before mid-day heat.
Drive into the Western Ghats toward Manimuthar Dam and Manimuthar Falls (approx 45–75 minutes depending on route/traffic); the road is scenic with roadside viewpoints — check local directions and drive safely.
Visit the Manimuthar waterfall and dam area for quieter waterfalls, scenic reservoir views and birdlife; most public areas are accessible 7:00am–5:00pm but confirm local gate times and any small entry/parking fee.
Take a short guided or self-led nature walk to a nearby viewpoint or forested spot — the Western Ghats are rich in flora and birds; if you want a longer trek (e.g., Agasthiyar/Agastya Hill), pre-book permits and guides as required.
Stop at a clean roadside restaurant or hotel on the return route to Thenkasi and try local rice meals, fish curry, or a thali; many places serve full meals from 12:00pm–3:00pm.
Back in Thenkasi, use the afternoon for any missed local temples, a coffee/tea break or shopping for local sweets and spices before you depart; temples re-open for evening darshan (typically 4:00pm).
Return to your hotel to relax, freshen up and pack. If you have extra time, you can return briefly to the temple for evening aarti (4:00pm–7:30pm typical hours).
Final dinner at a local restaurant near the bus/rail station if you have an evening departure; sample one last regional meal (rice with a spicy mutton or fish curry) and head to your onward transport.
