Ashtamudi Lake

Introduction: The Gateway to Kerala's Backwaters

Spanning an area of over 61 square kilometers in the Kollam district of Kerala, Ashtamudi Lake (Ashtamudi Kayal) is the second largest lake and wetland ecosystem in God's Own Country. Celebrated worldwide as the 'Gateway to the Backwaters of Kerala', Ashtamudi derives its unique Malayalam name from its distinct topography—'Ashta' meaning eight and 'Mudi' meaning branches or braids—referring to the eight major sprawling arms that branch out into lush coconut groves, mangrove forests, and traditional island hamlets. Formed as an estuary fed primarily by the Kallada River before draining into the Arabian Sea at Needakara, Ashtamudi is a Ramsar-designated wetland of international importance.

Renowned for its serene environment, deep natural channels, and thriving aquatic biodiversity, Ashtamudi Lake offers a quiet, uncrowded alternative to the busier backwater channels of Alleppey. Surrounded by rustic fishing villages, traditional coir-weaving units, and luxury eco-resorts along its perimeter, Ashtamudi provides an ideal sanctuary for international travelers from the US, domestic tourists across India, and nature lovers seeking slow living. Whether you are gliding across glassy water arms aboard a traditional luxury houseboat (Kettuvallam), observing Chinese fishing nets against tropical sunsets, or taking an excursion to Munroe Island, Ashtamudi Lake captures the authentic aquatic soul of South Kerala.

History and Heritage: The Ancient Maritime Estuary

The history of Ashtamudi Lake is deeply intertwined with the ancient maritime trading legacy of Kollam (formerly Quilon). Dating back to Phoenician, Roman, Chinese, Arab, and European trade eras, Ashtamudi served as a natural inland harbor where merchant ships anchored to load Malabar black pepper, teak, cardamom, and coir products. Venetian traveler Marco Polo and Chinese voyager Zheng He both documented Quilon's thriving ports along Ashtamudi's channels during their historic medieval voyages.

Beyond its ancient trade roots, Ashtamudi Lake holds an important place in modern Kerala's maritime traditions and eco-conservation history. The lake is the birthplace of Kerala's famous 8-hour backwater cruise connecting Kollam to Alappuzha—the longest backwater cruise in the state. In 2002, recognizing its rich marine life, extensive mangrove coverage, and vital role as a breeding ground for commercial estuarine fish like the Karimeen (Pearl Spot), Ashtamudi was designated as a Ramsar Wetland Site under international conservation guidelines.
