Beneath the Blue: Snorkeling Hikkaduwa’s Coral Sanctuary
Sri Lanka’s clearest winter water, turtles on the glide, and a reef with a comeback story.
Morning breaks soft over the southwest coast of Sri Lanka, and Hikkaduwa’s reef wakes with it. The Indian Ocean exhales against the sand, then draws back, revealing a band of turquoise that dares you to wade in. From shore, the coral gardens are a suggestion—textures and shadows beneath quicksilver. Slip on a mask and the world clarifies: the reef yawns awake in full color, parrotfish chiseling loudly at coral, sergeant majors patrolling with nervous energy, and a green turtle glides past like an old friend who knows every alley in this underwater town.
Trail Wisdom
Go Early for Glassy Seas
Start soon after sunrise when wind is low and visibility typically peaks on this coast.
Choose Reef-Safe Sun Protection
Wear a long-sleeve rash guard and use mineral-based sunscreen to protect skin and the coral.
Mind Your Fins
Keep kicks small and stay horizontal to avoid stirring sand or bumping coral—buoyancy and awareness save reefs.
Follow the Guide, Not the Turtle
Maintain distance from wildlife and let the current carry you; guides know where visibility and safety are best.

Conservation Note
Use reef-safe sunscreen, don’t stand on coral, and avoid feeding turtles. Choose operators who use mooring buoys rather than anchors to protect the reef.
Hikkaduwa’s reef area was declared a sanctuary in 1979 and became a National Park in 2002, protecting one of Sri Lanka’s most accessible coral systems.
