Enjoy a calmer pace of sightseeing — and perhaps even get a little spiritual — at Kamakshi Amman Temple. If it's possible to venture inside, why not stick around for a moment or two of quiet meditation?
You'll be spoiled for sightseeing choice when in Mylapore Tiruvallikk. Kamakshi Amman Temple is a good place to start here, but there are many other worthwhile spots to explore. Marina Beach, Consulate General of the United States, Chennai, and Kapaleeswarar Temple are close to the place of worship and and will cap off your day nicely.
