Mirissa Dive Center has run diving and snorkelling tours from the beach town of Mirissa on Sri Lanka's south coast since 2011. A PADI operation with English and Sinhala speaking staff, it welcomes absolute beginners for Discover Scuba sessions as well as certified divers, and rents equipment for multi-day dive packages.

Reef dives mix with the center's signature experiences: snorkelling with whales and turtles when conditions and regulations allow. The south coast season runs roughly November to April, when seas are calm and visibility peaks. A 4.8 rating across roughly 1,500 reviews makes it one of the area's most established operators.
