Far from the bustling crowds of the northern islands, the “Secret Gilis” of Southwest Lombok offer a raw, untouched sanctuary for underwater enthusiasts. These tiny, often uninhabited specks of land—scattered across the pristine waters of Sekotong—are where the silence of the ocean meets crystal-clear visibility. For those looking to escape the typical tourist trail, these islands provide a “Deep Blue” experience characterized by vibrant soft corals, diverse macro life, and the serene isolation of the Indian Ocean’s calmer bays.
Gili Nanggu
serves as the ultimate gateway for snorkeling and diving, located just a short boat ride from the Tawun harbor in Sekotong. Known for its legendary “underwater garden,” this island is surrounded by shallow reefs where schools of colorful damselfish and clownfish greet you the moment you step into the water. The clarity here is exceptional, often likened to a natural swimming pool, making it the perfect spot for beginners to experience the vibrant biodiversity of Lombok’s southern seas in a calm, current-free environment.
Gili Kedis
is perhaps the most iconic of the Secret Gilis, often described as a “tiny heart-shaped island” consisting of nothing more than white sand and a few trees. While the island itself can be walked across in less than a minute, its surrounding seabed is a hidden treasure for macro diving and photography. Located just minutes from Gili Sudak, the underwater terrain here is home to rare nudibranchs and starfish resting on a bed of pristine white sand, offering a peaceful, shallow escape where the sunlight pierces through the water like liquid crystal.
Gili Sudak
offers a slightly deeper perspective, famous for its expansive seagrass beds and coral patches that attract a variety of unique marine life. Situated strategically between Nanggu and Kedis, this island is the ideal spot for a mid-day surface interval or a leisurely shore dive. The waters here are remarkably still, allowing for long, relaxed explorations of the reef edges where you can often spot seahorses and blue-spotted rays camouflaged against the sandy floor, providing a tranquil contrast to the more dramatic drift dives found elsewhere in Indonesia.
Gili Layar
is the true connoisseur’s choice for diving, located further west along the Sekotong peninsula near the more famous Gili Asahan. This island is renowned for its spectacular “Blue Coral” gardens, a rare sight that draws experienced divers looking for untouched reef systems. The underwater topography here is more varied, featuring gentle slopes and coral bommies that host a high concentration of reef sharks and large sea turtles. It remains one of the most quiet and pristine spots in the region, offering a sense of discovery that is increasingly hard to find.
Gili Asahan
completes the secret circuit as the most ecologically diverse of the southwest islands, offering a mix of wall dives and vibrant coral slopes. As the largest of the secret group, its surrounding waters benefit from richer currents that bring in larger pelagic species and maintain the health of its massive sea fans. The diving here is characterized by a “wild” feel, where the coral remains in near-perfect condition and the absence of large boat traffic ensures that the underwater world remains as silent and mystical as nature intended.
