Tucked away in the remote waters of the Andaman Sea, about 138-140 km northeast of Port Blair, lies Barren Island, home to India’s only active volcano. It’s also the only confirmed active volcano in all of South Asia. The island is part of the Andaman and Nicobar archipelago and is uninhabited, with a stark, otherworldly landscape shaped by centuries of volcanic activity. (Image: AI-Generated)
The volcano had been dormant for over 150 years until it erupted again in 1991, and it has shown intermittent activity ever since. In fact, it erupted twice in September 2025, following a nearby earthquake, raising fresh interest in its seismic behaviour. (Image: Pexels)
In a major boost to adventure tourism, the Andaman and Nicobar Administration launched a round-trip cruise service to Barren Island in October 2025. The passenger vessel ‘Sindhu’ completed its maiden voyage on October 25, 2025, carrying tourists and schoolchildren from Port Blair to the volcanic site. (Image: Pexels)

While disembarkation on the island is not allowed to protect its fragile ecosystem, the cruise offers panoramic views of the volcano’s smoldering cone, ash plumes, and rugged coastline from a safe distance. (Image: Pexels)
The island spans just over 3 square kilometers, but its geological significance is immense. It sits on the convergent boundary of the Indian and Burmese tectonic plates, making it a hotspot for seismic and volcanic activity. (Image: Pexels)
