• Chunnambar River Sanctuary (beyond the main boat house area):
Significance: While the Chunnambar Boat House is popular for accessing Paradise Beach, the extended river sanctuary area itself is an offbeat gem. This is where the Chunnambar River (the lower course of the Sankarabarani/Gingee River) flows, meeting the sea amidst lush greenery.
What to See/Do: Beyond the crowded boat house, explore the quieter stretches of the river by a private boat ride (if available), or just enjoy the tranquil riverside. It's excellent for birdwatching, photography, and peaceful picnics.
Experience: A serene escape often overlooked by tourists rushing to Paradise Beach, offering undisturbed natural beauty.
