Azhimukham (Mahe River Estuary)

Azhimukham is the estuary where the Mahe River (Mayyazhi River) meets the Arabian Sea at Mahe, an enclave of the Union Territory of Puducherry surrounded by Kerala. The site features a sandy river-mouth beach, fishing harbour, mangrove patches and a long breakwater walkway. It is notable for scenic sunset views, birdlife, and as a tranquil natural landmark marking the historic boundary of former French Mahe.

Visitors can expect a wide estuarine landscape where the calm river meets the sea, with sandy banks, a stone breakwater/pier extending into the water, fishing boats anchored near the harbour, and mangrove vegetation along the river edge. The area offers open views of the Arabian Sea, sunset vistas, opportunities for photography, leisurely walks along the bund and beach, and observation of local fishing activity. There are no major built structures, the setting is natural and open.

Mahe was a former French colonial enclave from 1724 until its integration in 1954, and the Mahe River historically formed a natural boundary. The estuary area served as a port and fishing base and remains associated with the colonial heritage of Mahe town.

Locally called Azhimukham meaning river mouth in Malayalam, the estuary is central to the fishing community's livelihood and daily life. It is a popular leisure and sunset spot for residents of Mahe and surrounding North Malabar region.
