As Negombo is a year-round holiday destination, it offers a wide range of water activities, including surfing, wakeboarding, wakesurfing, water-skiing, parasailing, and more, typically organized by the resort's hotels. Some of these hotels provide equipment rental services.
Despite the coastal waters sometimes being muddy due to silt, water-based activities like snorkeling and diving remain popular. Snorkeling trips are arranged to clear bays, while diving adventures take tourists 20 kilometers offshore to explore coral reefs.
Additionally, there are activities that involve navigating the local rivers, such as rafting.
