Your travel guide for Sri Lanka

Batticaloa Lagoon is a significant water body in the eastern region of Sri Lanka. Covering more than 141 square kilometers, this lagoon offers a serene environment as well as a variety of activities for visitors. In this travel guide, we will delve into the details of this unique lagoon.


Batticaloa Lagoon is one of the largest and most remarkable lagoons in Sri Lanka. Stretching for an impressive 56 kilometers in length and having an average width of 4 kilometers, it offers an expansive area to explore. A narrow strip of land ranging from 100 meters to several kilometers in width separates the lagoon from the sea. This strip of land is characterized by sandy beaches on the ocean side and a diverse range of coastal vegetation.

The lagoon serves as an essential water source for the surrounding areas and is crucial for irrigation and agriculture. Fishing is another significant activity, providing livelihoods for local communities living along its banks. 

Unique Features of Batticaloa Lagoon

Salinity Levels

The lagoon's unique mix of both saltwater from the Indian Ocean and freshwater from the inland rivers leads to varying salinity levels throughout its expanse. This creates different micro-environments or zones within the lagoon, each supporting a specific set of plant and animal life. These zones are fascinating to study and observe, as they offer a glimpse into how adaptable life can be under differing conditions.

Mangrove Forests

The mangrove forests that line certain parts of the lagoon are not just any forests; they are complex ecosystems that serve multiple functions. These mangroves act as a buffer against coastal erosion, protecting the land and human settlements from the impact of the sea. They also serve as nurseries for various fish species, contributing to the lagoon's role as a significant fishing resource for the local community.

Fishing Communities and Traditional Methods

Fishing is a major activity in the area, and the lagoon supports several fishing communities that have been living and working here for generations. What makes this especially interesting is the use of traditional fishing methods. For instance, you may see fishermen using "kothu valai," a type of stationary lift net, or "garadi valai," a cast net used in shallow waters. These traditional techniques add a cultural layer to the lagoon's already diverse offerings.

Small Islands

Within the expanse of the lagoon are several small islands and islets. These add a level of complexity to the lagoon's geography and are often rich in vegetation and bird life. Some of these islands are accessible by boat and offer additional opportunities for exploration.

Flora and Fauna

Plant Life

The vegetation around the lagoon is primarily made up of mangrove trees like Rhizophora and Avicennia. These mangroves are critical to the lagoon's ecology, serving as breeding grounds for many fish species and protecting the coastline from erosion. In addition to mangroves, you'll find a variety of seagrasses like Halophila and Thalassia. These seagrasses form underwater meadows that are crucial for marine life, acting as food sources and hiding places for smaller organisms.

Diverse Fish Population

Fishing is a major livelihood for local communities. The lagoon is teeming with fish. Common species include mullet, sea bass, and catfish. More exotic species, like the brackish water pufferfish, can also be found here. Different zones of the lagoon, defined by their salinity levels, support different fish populations, making it an interesting place for angling and research alike.

Bird Species

Birdwatchers will find the lagoon a paradise, especially during the migratory season. Local species like egrets, pelicans, and kingfishers are common sights. Migratory birds such as sandpipers and plovers also visit the lagoon, making it a key location for avian biodiversity. Various points around the lagoon serve as excellent spots for birdwatching, offering chances to see these species in their natural habitats.

Things to Do

Boating Tours

Boating is one of the most popular activities for visitors. Several operators offer comprehensive tours that take you across different parts of the lagoon. A local guide often accompanies these tours. The guide can provide insights into the lagoon's ecology, the bird species you might encounter, and the methods used by local fishermen. Some tours even include stops at smaller islands within the lagoon, giving you a well-rounded experience.

Fishing Experiences

Fishing is not just a livelihood for locals; it can also be a captivating activity for visitors. Several options allow you to try your hand at fishing. You can either go with local fishermen in their traditional boats or try angling from the banks. It's a unique way to understand the techniques used by the community, engage with locals, and even catch your own dinner!

Bird Watching Expeditions

Birdwatching is another popular activity, especially during the migratory seasons. Specific points around the lagoon serve as excellent vantage spots. Some tour operators specialize in bird-watching tours, complete with guides who can help identify the different species. Binoculars and cameras with zoom lenses are recommended for the best experience.

Landscape and Wildlife Photography

If you are a photography enthusiast, Batticaloa Lagoon offers endless opportunities for both landscape and wildlife photography. The varying salinity levels create different visual environments, from the color of the water to the types of vegetation. Sunrise and sunset are particularly picturesque, offering excellent lighting conditions. Wildlife photography is also rewarding, with the variety of bird species and other marine life.

Kayaking and Canoeing

For those who prefer a more hands-on experience, kayaking and canoeing are available. These activities allow you to explore the lagoon at your own pace. Paddling through the waters gives you a different perspective and allows for a closer look at the mangrove forests and the creatures that inhabit them.
