Diving and Snorkelling in Hikkaduwa: Reef, Wrecks, and Turtles

Hikkaduwa has been the main diving destination on Sri Lanka’s southwest coast since the 1970s. The draw is accessibility: the reef starts 50m from the beach, the wrecks sit in depths suited to recreational divers, and the sea turtle population is large enough that encounters are reliably close to guaranteed between November and April. The dive schools on the main beach road are concentrated and competitive, making it easy to shop around.

Snorkelling: Hikkaduwa Coral Reef

The reef runs parallel to the main beach, 50–200m offshore, at 2–5m depth. The easiest access is by swimming from the beach in front of the reef park markers, or by taking a short glass-bottom boat or snorkel boat from the beach (LKR 500–1,000 for a 30-minute tour to the best sections).

Sea turtles: Four resident green sea turtles (Chelonia mydas) are regularly sighted on the reef. They have been present for years and are accustomed to snorkellers approaching slowly. The key approach rule is to stay at the surface and let the turtles come up to breathe rather than chasing them down — they’re curious and often approach of their own accord. Do not touch, block their path, or crowd around them. The turtles are also sometimes seen resting on the sand patches between coral heads.

Coral status: The Hikkaduwa reef suffered from bleaching events — most severely in 1998 and again in 2016 — that damaged large sections. Recovery has been gradual and is continuing. Some sections of the reef show good regrowth with fish populations, including parrotfish, pufferfish, angelfish, and lionfish. Other areas remain bleached. Visibility on a clear day is 5–10m; in the period after heavy rain it can drop to 2–3m.

Best conditions: November through April (northeast monsoon season on the southwest coast brings calm, clear water). The west-facing coast enters the southwest monsoon from May through October, which brings rougher surf, reduced visibility, and higher risk to snorkellers. Most dive schools note that November–March is peak diving and snorkelling season.

Diving: Sites and Conditions

Hikkaduwa Coral Garden

The main recreational dive site — a section of the reef at 6–10m depth, suitable for all certification levels and for beginner divers on Discover Scuba sessions. Fish life is good: dense schools of sergeant majors, snappers, and pufferfish among the coral heads. Turtle encounters are common on this site.

The site is sheltered and has minimal current, making it a reliable first dive for anyone new to Sri Lanka’s conditions. Visibility averages 8–12m in season.

Earl of Shaftesbury

A 19th-century British steam cargo vessel lying at 18m depth, 2km offshore. The wreck is largely intact — the hull is recognisable and penetration diving is possible in the cargo hold sections. The wreck is covered in soft corals and home to lionfish, grouper, and sea fans. Recommended for: divers with open water certification and some wreck experience; penetration sections for advanced divers. A dive with guide from a local school takes approximately 45 minutes.

Conch Wreck

A smaller vessel at 15m, closer to shore than the Earl of Shaftesbury. Good for intermediate divers. Coral encrustation is significant — the wreck has been down long enough that it functions more as an artificial reef than a recognisable shipwreck. Lionfish are reliably present.

Kirinda Wreck

Deeper than the other Hikkaduwa wrecks — only suitable for advanced divers. Check with individual dive schools for current depth and access conditions.

PADI Courses and Dive Schools

Dive schools are concentrated along the 2km beach road between Hikkaduwa junction and Narigama. Most offer the full PADI recreational curriculum from beginner to divemaster level.

Discover Scuba Diving (DSD): Introduction session for non-certified divers — brief surface briefing followed by a shallow guided dive to 6–8m on the coral garden. Cost: approximately $50–60 including equipment. No prior experience required.

PADI Open Water Course: The entry-level certification for independent diving worldwide. Completed over 3–4 days, covering two confined water sessions (swimming pool or sheltered beach) and four open water dives. Cost: approximately $300–350 at Hikkaduwa schools. The certification is internationally recognised and valid for life.

PADI Advanced Open Water: 2-day course adding five speciality dives (typically navigation, deep, peak performance buoyancy, and two electives). Cost: $200–250. Builds on the skills needed for wreck diving.

Equipment check: Before committing to a dive with a school, check the condition of BCD, regulators, and wetsuits. Standards vary between operations. Reputable schools should have maintained equipment with recent service records visible on request.

Turtle Hatcheries

Several private turtle hatcheries operate along the Hikkaduwa beach road. These collect freshly laid sea turtle eggs from nesting beaches and incubate them in protected compounds to shield them from poaching and predation. Entry costs $5–10 and visitors see hatchlings at various stages of development.

The hatchery model has limitations — hatchlings kept in small tanks for extended periods before release can have reduced survival rates, and some facilities hold adult turtles, which is ethically questionable. If you visit, look for operations that release hatchlings promptly (within days of hatching) and do not keep adult animals on permanent display.

Witnessing a release — hatchlings carried to the shoreline after dark and walked into the breaking waves — is a genuine experience. Ask your guesthouse or dive school which facility practices the most responsible release procedures.
