Diving and Snorkeling in Sri Lanka

Sri Lanka is emerging as a prime destination for diving and snorkeling, thanks to its growing tourism infrastructure and diverse marine ecosystems. From coral reefs teeming with life to historic shipwrecks, the island offers countless underwater adventures. Here’s an updated guide to some of the best diving and snorkeling spots across Sri Lanka.

Diving & Snorkeling Highlights

Diving is particularly popular in resort towns like Negombo, Bentota, Unawatuna, and Hikkaduwa—the latter being a top choice for its vibrant underwater landscapes. Although there are fantastic spots all around the island, many remain relatively untouched, offering unique opportunities for exploration.

Seasonal Diving

With Sri Lanka’s two distinct monsoon seasons, you can dive year-round by choosing the right coast based on the season.
