Situated along the southwest coast of Sri Lanka near Hikkaduwa, this rocky reef formation drops toward the seabed where branching black coral bushes thrive on granite boulders. The topography features gentle swim-throughs and crevices that shelter macro critters alongside passing schools of reef fish.

Resting on a sandy seabed off the coast of Batticaloa, this historic steamship wreck is characterized by its prominent marine boilers and collapsed iron hull framing. The scattered metal structure functions as an artificial reef in shallow water, attracting schools of juvenile reef fish and benthic dwellers. Because the site sits close to shore, it offers a relaxed dive suited for exploring oxidized machinery and searching crevices for macro critters.

Located off Sri Lanka's southernmost cape near the historic lighthouse, Dondra Point features submerged granite boulders, rocky ledges, and hard coral formations facing the open Indian Ocean. Currents sweep across the point, attracting roving pelagics while resident morays and reef fish shelter within the rocky crevices.

The Earl of Shaftesbury was a four-masted iron sailing ship built in 1883 that sank off Akurala Reef after catching fire while carrying a cargo of coal. Today, the scattered wreckage rests upright on a sandy bottom, with massive structural frames, iron ribs, and deck machinery visible across the site. Soft corals and encrusting sponges claim the historic metalwork, creating shelter for reef fish and transient pelagics along Sri Lanka's southwest coast.

Located off the coast of Unawatuna near Galle, this site takes its Sinhala name from the massive granite boulders stacked upon one another. The formation creates an intricate terrain of gullies, caverns, and narrow swim-throughs resting on a sandy seabed. Divers navigate around towering rock faces adorned with soft corals, seafans, and sponges while pelagics drift past in the open water.

Goda Gala sits just offshore along Sri Lanka's southwestern coastline, featuring an arrangement of submerged granite boulders and hard coral formations. Cracks and hollows throughout the rock base provide shelter for nocturnal predators and macro life, while open-water schooling fish cruise across the upper reef flats.

Sunk off the coast of Batticaloa by Japanese dive bombers during World War II, this historic vessel is the world's first purpose-built aircraft carrier. The massive hull rests on its port side on the open seabed, offering an imposing profile complete with intact gun turrets, control tower, and aircraft crane machinery. Thick black coral trees and soft corals carpet much of the steel plating, while large pelagics patrol the surrounding open blue.

Rising from the sandy seabed off the coast of Hikkaduwa, Kirala Gala features large granite boulders and pinnacles. Open-ocean currents attract schools of pelagic predators to these rock structures, making it one of the deeper offshore highlights of Sri Lanka's southwest coast. Divers typically descend along a mooring line directly onto the rock tops to explore the crevices and overhangs draped in soft corals.

Knife Rock is a granite reef formation located off the coast of Trincomalee in eastern Sri Lanka. The submerged boulder structure features rugged crevices, ledges, and rocky gullies that shelter a high density of macro life alongside resident reef fish. Divers encounter gentle slopes transitioning into sand patches where rays and bottom dwellers rest.

Situated off the coast of Mirissa, this rocky outcrop features large granite boulders, fissures, and overhangs resting on a sandy seabed. As the name suggests, the site hosts an impressive concentration of moray eels sheltering inside crevices and rock hollows. Ocean swells can sweep through the shallower sections, but the labyrinthine rock formations provide ample shelter for reef critters and wandering pelagics.

Located just off the coast of Unawatuna, this shallow fringing reef features granite boulders scattered across sandy gullies and patches of hard corals. Divers encounter reef fish cruising along the gentle slopes, with crevices sheltering crustaceans and smaller benthic species.

Navy Island sits near the entrance of Trincomalee's natural harbor, offering sheltered shallow reef diving characterized by granite boulder formations and patchy hard coral growth. The seabed transitions from rocky outcrops to sandy slopes where bottom-dwellers hunt and shelter. Because of its protected position against heavy ocean swells, it serves as a dependable site when outer exposed reefs encounter stronger surge.

Developed by the Sri Lanka Navy off Sandy Bay in Trincomalee, this artificial reef project serves both as an underwater gallery and a marine habitat sanctuary. The seafloor features an array of submerged statues, decommissioned naval structures, concrete artwork, and small vessel remnants designed to encourage coral colonization. Divers navigate through sculpted exhibits resting on a predominantly sandy seabed, observing how fast marine flora and fauna have taken hold of the hard substrates.

Located off the seaward edge of Pigeon Island National Park near Nilaveli, this site drops away from the shallow fringing reef into deeper rocky slopes and sand patches. The outer profile exposes it to gentle oceanic swells and occasional pelagic visitors while maintaining healthy stands of hard coral interspersed with large granite boulders.

Located within the protected waters of Pigeon Island National Park off Nilaveli, this site features large granite boulders intermingled with hard coral gardens and sandy channels. Blacktip reef sharks frequently patrol the perimeter of the rock formations, while juvenile marine life seeks refuge among the branching Acropora corals.

Situated along the southern coast of Matara, Polhena Reef features a protected inshore lagoon that slopes gently out to an offshore barrier. Divers navigate scattered coral bommies, sandy gullies, and rocky outcrops that host resident green sea turtles grazing on algae beds. The sheltered inner reef transitions into a livelier outer slope where schools of reef fish take shelter from coastal currents.

The SS Conch was an early ocean-going steam oil tanker that struck the Akurala reef and sank in 1903. Broken into separate sections scattered over the seabed, the wreckage features massive boilers, engine parts, and twisted iron hull plates overgrown with hard corals and encrusting sponges. Divers can explore open framework sections and examine machinery while schools of reef fish shelter around the metal structures.

The SS Orestes was a British steamship that sank off the coast of Galle in the late nineteenth century. Today, the wreckage sits scattered over a mixed bottom of sand and rocky reef. While the hull has broken down over time, large structural components including the engine block, boilers, and propeller shaft remain clearly discernible and encrusted with marine life.

The SS Rangoon is a historic nineteenth-century steamship that sank upright just outside Galle Harbour. Built in Newcastle in the eighteen-sixties, this British vessel remains largely intact on the seabed, showcasing an ornate bow and classic iron hull construction. Because of its depth and exposed offshore position, the wreck attracts schooling pelagics and an extensive coating of marine growth across its machinery and decks.

White Rock sits off the coast of Batticaloa, characterized by massive granite boulder formations rising from a sandy seabed. Soft corals and encrusting sponges cover the rocks, creating shelter for reef fish and macro critters. Calm morning conditions during the east coast diving season make this rocky reef accessible for open water exploration and underwater photography.
