Overview

Krakatoa (Krakatau), Indonesia Cruise Port

Krakatoa, or Krakatau, is an active volcanic island complex located in the Sunda Strait between the islands of Java and Sumatra in Indonesia. While the name "Krakatoa" often refers to the original volcano that famously erupted in a cataclysmic event in 1883, the current active volcano is Anak Krakatau ("Child of Krakatoa"), which emerged from the caldera left by that devastating explosion.

The 1883 eruption of Krakatoa was one of the most powerful and destructive volcanic events in recorded history, causing massive tsunamis that killed tens of thousands and impacting global climate and weather patterns for years. Today, Anak Krakatau continues to be an active and growing volcano, offering a unique opportunity to witness geological forces at work. The surrounding islands, remnants of the original Krakatoa, provide a stark reminder of the volcano's immense power. Visiting Krakatoa is a thrilling, often challenging, expedition for those fascinated by volcanoes, natural history, and the raw power of the Earth.

Top Things to Do in Zhoushan, China

Witness Anak Krakatau from a Safe Distance

The main objective is to witness Anak Krakatau, the active "Child of Krakatoa," from a safe distance. Depending on the volcano's current activity level, tours will approach by boat, allowing for observations of smoke plumes, ash emissions, and potentially small eruptions.

Tip: Volcanic activity varies greatly. Always adhere to exclusion zones and follow your guide's instructions. The best views are often from the boat or a nearby island.

Explore the Islands of the Krakatoa Archipelago

Take a boat tour around the remaining islands of the Krakatoa complex: Rakata (the remnant of the original Krakatoa's cone), Sertung, and Panjang (Long Island). These islands, barren in places and covered in new vegetation in others, offer unique geological formations and a sense of the scale of the 1883 event.

Tip: Look for the steep, sheer cliff face of Rakata, which is a cross-section of the original volcano.

Hike on Anak Krakatau (if conditions allow)

If the volcano's activity level permits and it's deemed safe by authorities, some tours may offer the opportunity to hike partway up Anak Krakatau. This provides an incredibly immersive experience, allowing you to walk on recent lava flows and volcanic ash, feeling the raw power of the landscape.

Tip: This is a challenging hike over uneven, volcanic terrain. Wear sturdy closed-toe shoes. Check the latest safety advisories before planning such an activity.

Snorkel or Dive in the Surrounding Waters

The waters around the Krakatoa complex, despite the volcanic activity, can offer opportunities for snorkeling or diving. While not a primary coral reef destination, you might find interesting marine life and unique underwater topography shaped by the volcanic activity.

Tip: Inquire with your tour operator about snorkeling/diving conditions and opportunities, as clarity and marine life can vary.

Visit the Black Sand Beaches and Observe Volcanic Material

Explore the unique black sand beaches formed by volcanic ash and pumice. Collect volcanic rock fragments (responsibly, if permitted) and observe how new life is slowly recolonizing the stark volcanic landscape.

Tip: The contrast of the dark sand against the blue sea can be quite striking for photography.

Learn About the 1883 Eruption and its Global Impact

Your guide will provide detailed information about the catastrophic 1883 eruption of Krakatoa, its devastating tsunamis, and its far-reaching global effects on climate, sunsets, and even sounds heard around the world. This historical context enriches the entire visit.

Tip: Reading about the 1883 eruption before your trip will deepen your appreciation for the site.
