Diving with The Largest Coral Colony in Nusa Penida “Ocean Gardener”

About this tour

Nusa Penida, a breathtaking island southeast of Bali, has long captivated divers and ocean lovers with its rich marine biodiversity. Recently, the island drew global attention after the discovery of what is believed to be the largest coral colony in Nusa Penida—and possibly the world. This extraordinary reef, composed of the Galaxea astreata species, spans over 4,000 square meters and reaches an impressive 10 meters in height. It measures 58 meters in width and stretches 71 meters in length.

The discovery was led by Ocean Gardener, a marine conservation group based in Indonesia known for its dedication to coral reef education and restoration. Their team conducted detailed measurements and confirmed that this single coral colony is among the largest documented in modern marine science.

Where Is the Coral Colony Located?

The giant coral reef lies just offshore from Sental Village, on the north coast of Nusa Penida. This site benefits from the nutrient-rich ocean currents that flow through the Lombok Strait, a key junction where waters from the Pacific Ocean merge into the Indian Ocean. This dynamic marine environment creates ideal conditions for coral growth and health.

Thanks to its strategic location and protected marine zoning, the coral reef has been able to grow and thrive naturally for decades—possibly even centuries.

Why Choose Coral Diving in Nusa Penida?

Joining a coral diving tour in Nusa Penida offers far more than a typical dive. Here, you’re not just witnessing coral—you’re exploring what could be the largest living coral colony in Nusa Penida. This dive site is ideal for eco-conscious travelers, marine biology enthusiasts, and divers who want to experience the ocean on a deeper level.

The reef is a living monument to the resilience and beauty of marine life. Coral-focused tours not only allow you to observe this remarkable ecosystem but also educate participants about reef health, marine species, and the importance of conservation.

Aside from the coral colony, Nusa Penida is also a hotspot for manta rays, sea turtles, and the elusive mola-mola (ocean sunfish), making it a dream destination for every diver.
