Early breakfast in Chennai before you drive: Saravana Bhavan (T. Nagar) offers consistent South Indian meals and opens ~7:00am; good for a hearty dosa/idli start.
Explore UNESCO-style open-air rock temples: Shore Temple (scenic seaside) and Pancha Rathas; best visited in the morning to avoid heat. Typical visiting hours ~6:00am–6:00pm.
Visit the historic Nataraja Temple (important Shaiva centre). Temple darshan hours frequently: morning 5:30–12:30 and evening 4:00–8:30 — plan to be there for the afternoon or evening puja if midday closure applies.
Explore the palace complex and Saraswathi Mahal Library (library open approx 9:00–4:00pm; verify hours and closures in advance) to see bronze and manuscript collections.
Short morning drive (~1.25–1.5 h) to Trichy/Srirangam; arrive in time for early-morning Kaveri snanam (river bath) at the ghat — dawn is traditional and peaceful.
Breakfast at a local idli/dosa shop in Trichy to refresh after the river dip; simple, clean and nearby options like Murugan Idli are usually open early.
Visit the expansive Srirangam Temple complex — usually open 4:30–12:00 and 16:00–20:00; plan for morning darshan and a walk of the prakarams (enclosures).
Visit the Palani Murugan Temple perched on a hill. Temple open hours commonly from early morning to late evening (~5:00–21:00). Choose ropeway or vehicles if avoiding the steep foot climb.
Visit the famous Ramanathaswamy Temple (darshan hours typically 5:00–12:30 and 16:00–21:00); note corridor queues and plan accordingly for pradakshina (long corridors).
Leave very early (4:00–5:00am) for Dhanushkodi to catch sunrise over the ruins and the sea; road access is typically permitted but check local conditions as weather/maintenance can close stretches.
See the hauntingly beautiful ghost town, the jetty, and the sunrise over the point where Ram Setu/Adam’s Bridge is visible; avoid driving on soft sands and follow local guides.
Book a local licensed boat (when available) for a guided view of the chain of shoals popularly called Ram Setu/Adam's Bridge; boats typically run at dawn and cost depends on size — private boats ~INR1500–3000.
If you want additional darshan or to complete rituals, use the afternoon slot (temple opens again around 4:00pm for evening sevas) or attend local pujas arranged by priests.
Visit Kapaleeswarar Temple in Mylapore (typically open early morning to noon and late afternoon to evening); experience Dravidian temple architecture and lively neighbourhood.
Enjoy a quality lunch at The Raintree or a recommended coastal restaurant for a refined end to the trip; Chennai has many reliable eateries serving South Indian and pan-Indian cuisine.
Visit Fort St. George museum or the Government Museum (check each site's hours—Government Museum approx 9:00–5:00, usually closed Fridays). Both give colonial and cultural context to Chennai.
Use the evening for shopping at T. Nagar / Pondy Bazaar or transfer to airport/rail station for onward travel; allow traffic time to reach terminals (peak evening congestion).
