is one day enough to complete kanchipuram temples and give me idea how to plan my one day trip in kanchipuram
One day you can visit the important temples, not all. Provided you start early.
Ekambareswarar Temple & Kamakshi Amman Temple - Very close to railway stn can walk.
Kanchi Kailasanathar Temple - Slightly far off, but still can walk or take Auto.
Varadharaja Perumal Temple - On other end of the town need to use public transport / auto.
Dont miss Kancipural Koil Idli from Ekambareswarar Temple / Varadharaja Perumal Temple.
If you are traveling through Public transport ,after reaching Kanchipuram you can hire autos there who will take you to all main temples in kanchipuram.I think i paid Rs 350(Not sure,it was two years back) for going to all main temples listed above and yes one day is enough to cover all main temples in kanchipuram.
You did not mention your start point. Wherever you start from, You should reach Kanchipuram at 7am. If it is a weekend, there will be heavy crowd in Kamatchi Amman temple. Say you need to wait approx 1 hour for dharshan. So you should reach Kanchipuram at 6am on Weekends.
6am - 8am - Kamatchi Amman temple,
8am - 8:30am - Ulagalandha perumal temple. 100 metres from Kamatchi Amman temple.
8:30am - 9:30am - Breakfast
9:30am - 10:30am - Ekambaranathar temple (Ekambareswarar Temple)
10:30am - 12 - Kailasanathar temple.
All temples closed by 12 and re-opens at 4pm.
You can finish lunch and do some shopping at this time.
4pm to 6pm - Varadharaja perumal temple.
Ladies or Gents - Do Not wear Shorts / Jeans / T-Shirts. Keep a dhoti with you in case if they insist. (They do sometimes)
