When in Pondicherry, make sure to visit this beach. The sand doesn't stick, and the ocean bed is relatively flat, making it safer for small kids. There are plenty of eating outlets nearby, as well as a lighthouse. Additionally, a short distance away, you can enjoy a boat ride through a small mangrove forest for 400 per person.
You may have overlooked it a few times, but believe me, it could be the best beach if you visit, especially in the evening after 5.
There is a viewing area with benches around the corner where you can see the beach, but it is not accessible from there. The next entrance allows you to access the beach, where you can enjoy it. However, the shore is steep and there are no lifeguards present. The beach is relatively clean, but not up to the standard you would expect.
