Lekuan 1, 2, and 3, Bunaken: wall diving in Sulawesi

Diving Lekuan 1, 2, and 3 immediately plunges you into the heart of Bunaken's famed marine diversity. As you descend, the sheer walls unfold beneath you, often dropping to around 25 meters before gracefully sloping out to greater depths. These are not just walls; they are vertical gardens, densely packed with an astonishing array of enormous sponges, both hard and soft corals, creating intricate habitats and a vibrant tapestry of life down the entire face.

The sheer scale of the coral and sponge growth here is what truly sets Lekuan apart. You'll find yourself navigating past colossal barrel sponges and intricate gorgonians that cling to the wall, each corner and crevice a potential hiding spot for smaller critters. The moderate current, a characteristic of this site, often helps to keep these walls pristine and well-nourished, ensuring a rich display of colour and activity as you drift gently along.

While drifting, keep your eyes peeled for the resident green sea turtles, often found gracefully cruising past or resting on ledges. Reef sharks are also a common sight, patrolling the deeper sections along the drop-off, adding a thrilling dimension to the dive experience. The combination of grand topography and the presence of larger marine life makes for an engaging wide-angle perspective.

For those with an eye for the intricate, Lekuan’s walls do not disappoint on the macro front. Take the time to scrutinize the coral formations and sponges, and you might discover pygmy seahorses, perfectly camouflaged among the gorgonians. Orangutan crabs meticulously pick their way across soft corals, and a myriad of nudibranchs display their flamboyant colours against the rich backdrop, rewarding patient observation.

The visibility at Lekuan typically ranges from 15 to 25 meters, providing clear views of the extensive wall system and its inhabitants. The way the sunlight filters through the water column, illuminating the vibrant colours of the corals and sponges, creates a constantly changing spectacle as you track your depth along the wall, making each moment underwater a visual feast.
