Embark on the Historic Kollam-to-Alappuzha Houseboat Cruise: Ashtamudi Lake is the starting point for the longest, most scenic backwater cruise in Kerala—an 8-hour epic voyage that links Kollam to Alleppey. Visitors can board a traditional, luxury wood-and-bamboo Kettuvallam (houseboat) to traverse the lake’s wide, windy expanses. Unlike shorter cruises, this cross-district journey takes you past isolated islands, deep mangrove tunnels, and rural lakefront villages, offering a complete, slow-motion immersion into the aquatic lifestyle of South Kerala.

Explore the Mangrove Sanctuary of Asramam Picnic Village: Located on the lush, urban shores of the lake in Kollam city, this sprawling 48-acre heritage park is a magnificent ecological asset. The area features a dense, protected mangrove forest that acts as a vital breeding ground for marine life and rare otters. Visitors can walk along the landscaped waterfront, view the 140-year-old British-built Asramam Guest House, and take specialized boat rides deep into the quiet, roots-entangled mangrove creeks where rare birds nest.

Visit the Clam Harvesting Village of Sambranikodi: For an immersive cultural experience, head to Sambranikodi, a unique fishing outpost located on the southern fringes of the lake. Here, a shallow mudflat emerges in the middle of the water during low tide, allowing visitors to step out of local wooden boats and literally walk in knee-deep water far from the shore. The village is famous for its sustainable, hand-harvested black clam industry, where you can watch local fishers dive bare-handed to collect shells from the lakebed.

Witness the Grandeur of Chinese Fishing Nets at Neendakara: Where the sprawling arms of Ashtamudi Lake open up into the Arabian Sea sits the historic port of Neendakara. The waterfront here is lined with massive, cantilevered Chinese fishing nets (Cheena Vala) that silhouetted against the sky. Watching the local fishing teams operate the complex weight-and-pulley systems to hoist up the evening catch against a blazing Malabar sunset is an architectural and cultural spectacle that dates back to the era of ancient silk-route trade.
