Indonesia is home to thousands of breathtaking islands, each offering its own unique charm. Among them, Pulau Kalong Rinca, also known as Flying Fox Island, stands out as a must-visit destination for nature lovers and adventure seekers. This small yet captivating island, located near Rinca Island in Komodo National Park, is famous for its massive population of flying foxes—large fruit bats that take flight in a mesmerizing display at sunset.
A Natural Spectacle at Dusk

The main highlight of Pulau Kalong is the spectacular sight of thousands of flying foxes soaring into the evening sky. As the sun begins to set, these nocturnal creatures awaken from their mangrove habitat and set off in search of food, creating a breathtaking silhouette against the orange and purple hues of the twilight sky. This unforgettable natural phenomenon attracts visitors from around the world who come to witness the island’s magic.
The sound of fluttering wings and high-pitched calls fills the air as the bats leave their nests in unison, providing an eerie yet awe-inspiring experience. Tourists often describe the moment as surreal, as the sheer number of flying foxes creates a dark cloud-like formation moving across the sky.
A Haven for Wildlife and Marine Beauty

Pulau Kalong is not just about flying foxes—it is also part of the rich ecosystem of Komodo National Park, a UNESCO World Heritage Site. The island is surrounded by crystal-clear waters teeming with marine life, making it a paradise for snorkelers and divers. Dolphins, sea turtles, and vibrant coral reefs add to the island’s allure, offering visitors a chance to experience the incredible biodiversity of the region.
The dense mangrove forests of Pulau Kalong serve as an essential habitat for the flying foxes, as well as many bird species, crabs, and other coastal wildlife. These mangroves also play a crucial role in maintaining the health of the surrounding marine ecosystem by preventing coastal erosion and serving as breeding grounds for fish.
Getting to Pulau Kalong Rinca

The best way to visit Pulau Kalong is by taking a boat tour from Labuan Bajo, the gateway to Komodo National Park. Flores Pristine Tour operators offer sunset cruises that combine a visit to Rinca Island, where you can see Komodo dragons, with an evening stop at Pulau Kalong to witness the flying foxes in action.
Most boat tours leave Labuan Bajo in the afternoon, stopping at Rinca Island or Padar Island for trekking and wildlife viewing before heading to Pulau Kalong for sunset. Some tours also include snorkeling stops at Pink Beach or Kanawa Island, making it a full-day adventure.
Best Time to Visit

While Pulau Kalong can be visited year-round, the best time to experience the flying foxes is during the dry season (April to October) when the skies are clear, and the sunsets are stunning. The months of June to August are particularly popular due to the pleasant weather and high chances of witnessing a spectacular bat migration.
For the best experience, visitors are advised to arrive before sunset and position themselves on the boat for an unobstructed view of the sky. Bringing a camera with low-light settings or a video recorder is highly recommended to capture the magical moment.
An Unforgettable Experience

A visit to Pulau Kalong Rinca is more than just a sightseeing trip—it’s an immersive encounter with nature. Whether you are a wildlife enthusiast, a photographer, or simply someone who appreciates stunning natural landscapes, this island promises an unforgettable experience.
For those seeking a unique adventure in Komodo National Park, Pulau Kalong Rinca should be on the itinerary. Witnessing the mass migration of flying foxes against the backdrop of a dramatic sunset is a once-in-a-lifetime experience that will stay with you forever.
