I recommend visiting - Mararikulam, India
Marari beach is the perfect place to unwind at the end of a trip of exploration. The beach itself is picturesque with the added advantage of remaining less touristy than some of the busier coastal resorts in India.
The beach also retains the authenticity of the area, as Keralan beaches cannot be privately owned, you will be able to see local fishermen bringing in delicious seafood. Relax on the palm fringed sand and take the opportunity to witness the beautiful sunset.
