1

Bentota Lagoon Fishing Boat Tour

The Bentota Lagoon is a stunning escape from city life, known for its rich biodiversity and quiet waters. A fishing boat tour here combines cultural insights with a touch of adventure, providing an intimate experience with the local marine life. Local guides take you through mangroves, where you can try traditional, sustainable fishing techniques, or enjoy the scenic beauty. The tour often includes opportunities to spot exotic birds, monitor lizards, and even crocodiles in their natural habitat.

Madu River Boat Tour

Considered one of the best destinations in the area, the Madu River, located near Balapitiya, is famous for its picturesque mangrove forests and abundant wildlife. A Madu River boat ride in Bentota takes you through narrow waterways lined with tropical greenery. You’ll see small islands with Buddhist temples, a variety of bird species, and even cinnamon plantations, available to visit through the tour from The Villa Bentota by KK Collection. One highlight of the tours is the chance to visit "fish therapy" stations, where small fish nibble on your feet for a natural exfoliation experience.

Mirissa is one of the best places in the world for whale watching. From November to April, head out to sea on boat tours for the chance to spot blue whales, sperm whales, and pods of local dolphins gliding across the waters of the Indian Ocean. Tours typically start early in the morning, providing stunning views of the sunrise over the ocean. Knowledgeable guides share insights about marine life. Be sure to select an ethical tour recommended by organisations like Lonely Planet, to ensure the safety and wellbeing of the whales.
