4. Muthupet -When you reach this secluded yet beautiful destination, you must visit mangroves’ lagoon for a boat ride. You will enjoy the experience. The lagoon is situated around 8 kms from Muthupet and can only be reached only by boat. The area is surrounded by a thick blanket of greenery (courtesy, forests). This place is perfect for a little introspection. The point where the brackish water joins the sea is beautiful. If you love photography and are a bird-watcher, this place is perfect for you. You will be able to set sights on a large number of bird species. You will enjoy the feeling of being cut out from the rest of the world.To reach the place, you can take a bus or train to Thanjavur and then hire a personal cab for the other leg of the journey. This is among the best places near Chennai for an offbeat weekend getaway.
