Mount Tambora: Pass The Sleeping Giant of Sumbawa Island

Sailing through the deep blue waters between Lombok and Flores, the sea stretches endlessly, and there, rising proudly from the heart of Sumbawa Island, stands a mountain wrapped in mist and memory of Mount Tambora.
To most travelers who join the Lombok Komodo tour, this mighty volcano is just a distant silhouette on the horizon. But to those who take the time to learn its story, Tambora is not just a mountain; it’s a living monument of earth’s fury and beauty, of destruction and rebirth.

The History of Tambora — When the Sky Turned Dark

In April 1815, the earth trembled violently beneath Sumbawa. The ground split open, and Mount Tambora erupted with a roar that echoed across the Indonesian archipelago.
It was not just another volcanic eruption. It was the most powerful volcanic explosion in recorded human history, ten times stronger than Krakatoa. The eruption sent ash 40 kilometers into the sky and turned day into night. It was heard as far as Sumatra and even parts of the Philippines.

The explosion killed tens of thousands and buried entire kingdoms like the Tambora Kingdom, lost beneath layers of ash and lava. The sky filled with volcanic dust, blocking sunlight across the planet. The following year, 1816, became known worldwide as “The Year Without a Summer.”
Crops failed in Europe and America, snow fell in June, and famine spread; all from the eruption of this one Indonesian volcano.

Today, when you look at Tambora’s vast crater, 7 kilometers wide and nearly a kilometer deep, it’s hard to imagine that once a thriving civilization stood where now only silence reigns.

How Tall is Mount Tambora?

Before its eruption, Tambora stood at over 4,300 meters, one of the tallest peaks in Indonesia. After the 1815 event, the top was blown away, reducing its height to around 2,850 meters. Even so, it remains the highest mountain on Sumbawa Island and one of the most majestic volcanoes in the country.

When sailing from Lombok to Komodo Island, many travelers notice its dramatic shape, like a crown of stone above the clouds, guarding the island of Sumbawa. It’s a reminder that Indonesia’s natural beauty was born from fire.

Can You Hike Mount Tambora?

Yes, and for adventurers, climbing Mount Tambora is one of the most rewarding hikes in Indonesia.
You can start your journey from Doro Peti Village, the most common route for those coming from the north. The trail passes through lush forests, bamboo groves, and highland savannas. Along the way, you might hear the distant sound of birds and see wild deer grazing in the misty valleys.

After a challenging 2–3 day trek, you’ll stand at the edge of the massive caldera; a breathtaking view into the heart of the volcano that changed the world. From there, you can even spot the sparkling blue sea stretching toward Komodo National Park, where your next adventure awaits.

For travelers who love both land and sea, Bose & KomodoExplore.com offers sailing programs that pass close to Tambora, allowing you to witness its grandeur from the comfort of your boat deck; an unforgettable view beneath the stars.

Is Mount Tambora Still Active?

Yes, Mount Tambora is still classified as an active volcano, though its eruptions today are small and closely monitored. The last minor eruption occurred in 1967, and since then, it has been relatively calm.
Scientists continue to study it, not only for its volcanic activity but also for the lessons it teaches about resilience and renewal.

The mountain’s slopes are now covered in dense forest, home to rare species of birds, butterflies, and even small mammals. The soil, enriched by volcanic ash, has given birth to fertile farmland and vibrant agriculture.

The Life Around Tambora — Nature Reborn

Where once ash rained from the sky, today green fields stretch as far as the eye can see. Farmers grow corn, coffee, cocoa, and cashew, while herders tend their cattle in open savannas. The air smells of earth and leaves, clean and alive.

Villages like Pancasila and Doro Peti rest peacefully at the mountain’s feet, where locals live in harmony with nature. They tell stories of their ancestors who witnessed the eruption, tales passed down through generations, like whispers from the past.

The Spirit of Adventure — Seeing Tambora from the Sea

If you’re joining a Komodo tour from Lombok, the journey often takes you along the northern coast of Sumbawa and that’s where you’ll see Tambora rising proudly from the horizon. The best part? During clear evenings, when the sun sets behind the mountain, the sky glows orange and gold, and the ocean mirrors the color of fire. As night falls, countless stars appear above your boat, and the Milky Way stretches right over Tambora’s shadow; a scene that few people on earth ever experience.

This is the magic of sailing with Bose & KomodoExplore.com — you don’t just visit places, you feel them.

Best Time to Visit Mount Tambora

The best time to explore or sail past Mount Tambora is during the dry season, from April to November.
During these months, the skies are clear, the sea is calm, and the mountain’s peak is often visible from the water. For trekkers, this season also provides safer trails and beautiful sunrise views from the crater rim.

If you’re planning to continue toward the Komodo Islands, this is also the ideal time to see manta rays, turtles, and colorful coral reefs along the way, another reason why this sailing route is one of the best in Indonesia.

How to Reach Mount Tambora

You can reach Mount Tambora from Bima or Dompu by car or motorbike. The nearest access point is Doro Peti Village, where most climbing expeditions begin. For those on a sailing adventure, your boat will pass nearby as you move from Kayangan Harbor in Lombok toward Komodo National Park. It’s the perfect opportunity to see the mountain from a unique ocean perspective.

Tambora’s Connection to Komodo — The Natural Route of Discovery

Mount Tambora may not be inside Komodo National Park, but it’s part of the same geological heartbeat, the Ring of Fire that gave birth to the islands, the reefs, and the dragons themselves. When you sail the route from Lombok to Komodo, you’re tracing a natural story of fire, sea, and evolution. Tambora, Komodo, Padar, and Rinca, all born from volcanoes that shaped the Indonesian archipelago.

For adventurers, this route is not just a holiday. It’s a living lesson in earth’s creation and a reminder of how life always finds a way to rise again from ashes.
