Overview

Satonda Island, Indonesia Cruise Port

Satonda Island, a small, uninhabited volcanic island located off the coast of Sumbawa in West Nusa Tenggara, Indonesia, offers an incredibly unique and tranquil experience for expedition cruise visitors. Formed by an ancient volcanic eruption, Satonda's most distinctive feature is its large, saltwater lake nestled within the caldera of its extinct volcano, a rare phenomenon created when a tsunami filled the crater with seawater. This secluded island is a natural marvel, providing a serene escape into a truly distinctive ecosystem.

A visit to Satonda Island is a journey into geological wonder and unspoiled natural beauty. The island is part of a marine protected area and is renowned not only for its fascinating lake but also for its pristine surrounding waters, teeming with vibrant coral reefs and diverse marine life. It invites cruise passengers to explore its unique geological formations, witness its nocturnal bat migrations, and immerse themselves in the quiet splendor of this remote Indonesian paradise.

Top Things to Do in Satonda Island, Indonesia

Swim or Kayak in the Saltwater Caldera Lake

Experience the unique opportunity to swim or kayak in Satonda's saltwater caldera lake. This ancient lake, filled with seawater, is surprisingly calm and offers a peaceful, otherworldly experience, distinct from the ocean waters surrounding the island.

Tip: The lake water is often warmer than the ocean. Ensure your expedition provides kayaks or access to the lake.

Snorkel or Dive in the Surrounding Coral Reefs

Immerse yourself in the vibrant underwater world by snorkeling or diving in the pristine coral reefs just offshore. The waters around Satonda are exceptionally clear and healthy, teeming with colorful fish, diverse corals, and other fascinating marine creatures.

Tip: Bring your own snorkeling gear if possible, or ensure your expedition provides it. Be mindful not to touch or stand on corals, as they are very fragile.

Hike to a Viewpoint Overlooking the Lake

Take a short, relatively easy hike to a viewpoint on the rim of the volcano, offering spectacular panoramic views of the saltwater caldera lake, the island's lush interior, and the vast expanse of the surrounding ocean.

Tip: Wear sturdy shoes, as the path can be uneven. The views are highly rewarding and offer great photo opportunities.

Witness the Bat Migration at Sunset

If your expedition schedule permits an evening stay, witness the incredible natural spectacle of thousands of fruit bats emerging from the island's caves at sunset. They fly in massive streams across the sky, heading towards nearby Sumbawa to feed.

Tip: This phenomenon is truly unique. Bring binoculars or a good camera for observing this amazing wildlife display.

Observe the Ancient "Wishing Trees"

Discover the unique "wishing trees" (also known as "lucky trees") found around the caldera lake. These trees are adorned with small pieces of coral, stones, and other natural objects left by visitors, following a local tradition to make a wish.

Tip: Participate respectfully in the tradition if you wish. It's a charming local custom.

Relax on the Beach and Enjoy the Tranquility

Spend time simply relaxing on the island's small, uncrowded beaches, enjoying the serene tranquility and the sounds of nature. The calm, clear waters are ideal for a leisurely swim or simply unwinding away from the world.

Tip: As an uninhabited island, facilities are non-existent. Bring all your own necessities: water, snacks, towel, and sun protection.
