Places to Stargaze on Chennai - Pondicherry

Hi All,
My son (7 years old) is very keen on stars & planets & we bought a telescope to get him started.

We are planning a trip to Pondicherry & wanted suggestions on good place to stargaze. We have a Celestron 6SE. This will be our first attempt, so looking for a safe & dark places that we can take a kid to?

Also, are any meetups planned we would love to join?

Thanks,
