Kalong Island: The Magical Bat Island of Komodo National Park

Kalong Island, also known as Bat Island, is one of the most fascinating stops in Komodo National Park. Unlike Padar Island with its iconic viewpoints or Pink Beach with its rare colored sand, Kalong Island’s beauty is revealed in the sky. Every evening, thousands of flying foxes (giant fruit bats) take off from the island’s mangrove forests, painting the sunset with dramatic silhouettes. For many travelers, watching this natural phenomenon is one of the highlights of a Komodo boat tour.

Where is Kalong Island Located?

Kalong Island is located between Rinca Island and Papagarang Island, within Komodo National Park, East Nusa Tenggara, Indonesia. The island itself is uninhabited by humans and covered almost entirely by dense mangroves, which provide a perfect home for the thousands of bats that live there.

Its strategic position makes it a popular stop for boats traveling between Labuan Bajo, Komodo Island, and Padar Island. Many Komodo tour packages include Kalong Island as a final stop of the day, allowing guests to enjoy the spectacular sunset before anchoring nearby for the night.

Why is it Called Kalong Island?

The word “kalong” in Bahasa Indonesia means “bat” or “flying fox.” The island gets its name from the massive population of fruit bats that live in the mangroves. At dusk, these bats leave their nests in huge flocks to search for food on the neighboring islands. The sight of thousands of wings against a glowing orange sky is what makes Kalong Island Komodo such a magical experience.

The Sunset Experience at Kalong Island

Sunset at Kalong Island is the main attraction. As the sun dips toward the horizon, the mangroves grow darker and the air begins to stir. Then, suddenly, the bats start to emerge in waves—hundreds at first, then thousands—filling the sky with movement. Their wings create a natural spectacle as they fly in coordinated streams, silhouetted against the fiery red and purple of the evening sky.

This moment is often described as spiritual by visitors. The contrast between the stillness of the sea, the glow of the sunset, and the energy of the bats creates an atmosphere unlike any other place in the world.

How to Get to Kalong Island from Labuan Bajo

The gateway to Kalong Island is Labuan Bajo on Flores Island. Here are the most common ways to reach it:

1. Day Tours by Speedboat: Many operators offer one-day trips that include Padar Island, Komodo Island, Pink Beach, and finish with Kalong Island at sunset.
2. Liveaboard Phinisi Trips: Traditional wooden boats (phinisi) offer 2–4 day cruises around Komodo National Park, almost always including Kalong Island as a sunset stop.
3. Private Boat Charters: If you want a tailored experience, chartering a private yacht or boat from Labuan Bajo allows you to enjoy Kalong Island at your own pace.

Best Time to Visit Kalong Island

While the bats fly year-round, the overall experience depends on the season:

• April – September (Dry Season): Clear skies and calm seas make this the most popular time to visit. Sunsets are more vibrant, creating perfect photography opportunities.
• October – November: Still relatively dry with fewer crowds, offering a quieter experience.
• December – March (Rainy Season): The mangroves are lush and green, but weather can be unpredictable, with occasional storms and rougher seas.

No matter the season, the best time to see bats at Kalong Island is just before sunset, usually between 6:00 PM and 7:00 PM.

The surrounding waters are rich with coral reefs, making it a great area for snorkeling if your tour includes a stop nearby before sunset.
