If you have more time, you can add a visit to the Varadharaja Perumal Temple, known for its 100-pillar mandapam. Those interested in history can also visit the Kanchipuram Government Museum, which exhibits sculptures and artifacts from the surrounding areas.
If you have less time, you can skip the Kanchi Kudhil and the shopping at silk saree weaving factories. Alternatively, you can combine both and visit the Sri Varadaraja Perumal Temple and the Kamakshi Amman Temple instead.
Remember to wear comfortable footwear and appropriate clothing while visiting the temples. It is also advisable to carry drinking water and sunscreen, especially during summers.
