Doro Peti Beach: The Hidden Black Sand Beauty on the Coast of Mount Tambora

Nestled along the northern coast of Sumbawa Island, Doro Peti Beach is a quiet and fascinating destination that combines natural beauty with dramatic history. This coastal gem lies on the Tambora Peninsula, an area forever shaped by the massive eruption of Mount Tambora in 1815, the largest volcanic eruption ever recorded in human history.

Today, Doro Peti offers a calm and pristine escape, where travelers can swim, snorkel, and enjoy the black volcanic sand born from one of the world’s most powerful natural events. It’s a peaceful reminder of nature’s strength and renewal.

The Legacy of Tambora’s 1815 Eruption

Over two centuries ago, Mount Tambora exploded with unimaginable force, sending ash and volcanic debris high into the stratosphere. The eruption of April 1815 remains the biggest volcanic eruption in recorded history, estimated to be more than 1,000 times stronger than the atomic bomb dropped on Hiroshima.

The sound of the explosion was heard as far as 2,000 kilometers away, reaching even to Sumatra and parts of Australia. The event caused global climate effects, 1816 became known as “The Year Without a Summer” due to volcanic ash spreading around the world. Entire villages around Tambora vanished, buried under thick layers of ash and lava.

Yet from that powerful destruction, nature created new landscapes, one of them being Doro Peti Beach, where black volcanic sand meets the deep blue sea.

Where is Doro Peti Beach?

Doro Peti Beach is located on the northern coast of Sumbawa Island, in the Dompu Regency, just below the slopes of Mount Tambora. It’s part of the Tambora coast, an area still rich with volcanic minerals and geological wonders.

Travelers usually reach Doro Peti as part of a 4D3N sailing trip from Lombok to Labuan Bajo with Bose KomodoExplore.com. The boats stop here to let guests enjoy swimming, snorkeling, and photography in one of the most unique coastal environments in Indonesia.

The Beauty of a Black Sand Beach

Unlike the white sandy shores common in many Indonesian islands, Doro Peti’s sand is black and shimmering, formed from cooled lava and volcanic minerals. When sunlight hits the shore, the sand glows with silver reflections, creating a mysterious yet captivating scene.

The contrast between the dark sand, the emerald-blue sea, and the green slopes of Mount Tambora in the background makes Doro Peti a paradise for photographers and nature lovers alike. It’s a place where history and beauty coexist in perfect harmony.

What Makes Doro Peti Beach Special

Although still relatively unknown to many tourists, Doro Peti offers several unique attractions that make it a must-visit stop during your sailing journey:

The underwater world around Doro Peti is calm and colorful. Just a few meters from the shore, you can snorkel among blue corals and schools of tiny tropical fish dancing in the clear water. The calm waves and good visibility make it a safe and enjoyable spot even for beginners.

Jump from the Boat

For adventure lovers, Doro Peti is one of the best spots to jump directly from the boat into the ocean. The sea here is deep and clean, surrounded by volcanic rock formations that add a dramatic edge to the landscape.

Peaceful and Untouched

Unlike crowded beaches in Bali or Lombok, Doro Peti remains quiet and untouched. The only sounds you’ll hear are the soft waves, the sea breeze, and the occasional song of seabirds flying over the black coast. It’s a perfect place to relax, meditate, or simply enjoy the rhythm of nature.

Photography Paradise
