Glide through the mangrove-lined channels and tiny islands of the Madu River estuary on a gentle boat safari that reveals a hidden side of Sri Lanka’s coastal ecosystem. Along the way, spot water monitors, fruit bats, and a wide variety of birdlife nesting in the mangroves, with stops at small island temples and a cinnamon-processing demonstration. The day concludes with a visit to a nearby turtle hatchery, where conservation efforts protect nesting sea turtles and their hatchlings, a relaxed, family-friendly outing suited to nature lovers of all ages.
