Muthupet Lagoon

Muthupet Lagoon is a large coastal lagoon and mangrove ecosystem located at Muthupet in Tiruvarur District, Tamil Nadu, at the southern end of the Cauvery Delta opening into the Palk Strait. It forms part of the Muthupet Mangrove Forest, one of the largest mangrove stretches in India. Notable for its dense mangroves, brackish waters, biodiversity and birdlife, the lagoon offers boat rides and nature observation in a protected wetland environment.

Visitors can expect a shallow brackish lagoon surrounded by dense mangrove forest with interconnected creeks and mudflats. The main visitor experience is a boat ride through mangrove channels to observe flora, fauna and migratory birds. A wooden walkway and watchtower near the forest entrance allow views of the lagoon. The setting is natural and tidal, with fishing boats, birdlife and mangrove vegetation as primary features.

Muthupet Lagoon is part of an ancient mangrove ecosystem at the tail end of the Cauvery River delta. The mangroves have historically protected the coast and supported traditional fishing communities. The area was notified as a reserve forest and has been managed by the Tamil Nadu Forest Department for conservation.

The lagoon supports the livelihood of local fishing communities and is valued for its ecological and educational importance. It is recognized as an important wetland for biodiversity and environmental awareness in Tamil Nadu.
