Try SCUBA for the first time in Unawatuna Bay: a three-hour intro that starts in a shallow training lagoon and finishes with a guided dive to Rock Island’s reef and wreck sights. Ideal for vacationers who want to breathe underwater without a full certification.
More ways to explore the area's outdoor wonders
A warm sea breeze lifts the scent of salt and frying coconut as you step into Sun Diving Centre on Unawatuna’s shoreline. After a quick cup of tea and a health form, you slip into a mask and fins and wade into a protected shallow lagoon where instructors guide your first breaths underwater. The lagoon’s surface tucks the ocean away; below, the reef waits, bold and curious.

Unawatuna’s reefs have long supported local fishing and sit a short distance from Galle, a major colonial port with Dutch-era ramparts that shaped regional maritime routes.
Conservation
Coral health here is variable; follow reef-safe practices, avoid touching marine life, and use operators that support local reef cleanups to reduce tourism impact.

Hydrate before you dive
Drink water before the briefing—local heat and adrenaline can dehydrate you quickly, which affects equalization and comfort underwater.
Use reef-safe sunscreen
Apply a reef-safe sunscreen or wear a long-sleeve rashguard to protect skin without harming coral.
Declare recent surgeries or congestion
If you've had recent ear, nasal, or sinus surgery or are congested, skip the dive and consult a physician—equalizing at depth requires clear Eustachian tubes.
Practice mask clearing in the lagoon
Take your time during the shallow practice; mastering mask and regulator skills in 1m water sets the tone for a relaxed main dive.
Swimwear
Wear under clothing for quick gearing and comfort in warm tropical water.
Reef-safe sunscreen
Protects skin from sun and minimizes damage to coral ecosystems.
Lightweight towel and change of clothes
A dry set keeps you comfortable after the boat return and gear rinse.
Thin neoprene top or rashguard
Adds sun and abrasion protection during surface intervals and in the lagoon.
