The Andaman and Nicobar Islands have entered the Guinness World Records book with two major underwater achievements completed on consecutive days near Swaraj Dweep, formerly known as Havelock Island. The record attempts, carried out in May 2025, have drawn attention to India’s growing focus on marine tourism, scuba diving and adventure sports in the island region.
The events were organised under strict Guinness World Records guidelines and involved trained divers, technical support teams and extensive planning to ensure safety underwater.
Tallest underwater human stack achieved
One of the records was created when a team of 14 divers formed the tallest underwater human stack ever attempted. The activity took place off the coast of Swaraj Dweep, one of the most popular tourist destinations in the Andaman and Nicobar Islands.
The underwater formation measured 22.3 metres in length. Guinness World Records rules required the formation to remain stable underwater for at least three minutes, and the team completed the challenge within the required time.
Lieutenant Governor of Andaman and Nicobar Islands, Admiral DK Joshi, also participated in the record attempt. According to NDTV, officials said the event required detailed coordination among divers, safety experts and underwater support teams because maintaining balance and communication underwater can be difficult during such formations.
The achievement has now officially become the tallest underwater human stack recorded in the world.
Largest underwater Indian national flag unfurled
A day before the human stack attempt, another Guinness World Record was created in the same region when divers unfurled what has been recognised as the world’s largest underwater Indian national flag.
The flag measured nearly 60 by 40 metre underwater. Divers worked together beneath the sea to spread and maintain the massive flag while adhering to the technical conditions set by Guinness World Records officials.
The event was also attended by Lieutenant Governor DK Joshi. Organisers said the underwater flag display was designed not only as a record attempt but also as a symbolic celebration of India’s connection with the ocean and the strategic importance of the Andaman and Nicobar Islands.
Months of preparation behind the events
Officials involved in the project said to NDTV that both record attempts were planned months in advance. Divers reportedly underwent training sessions and rehearsals before entering the water for the final events.
Weather conditions, underwater visibility and ocean currents were also considered while preparing for the attempts. Technical divers and marine support staff remained present throughout the operations to ensure safety and smooth coordination underwater.

Focus on tourism and marine activities
Known for clear waters, coral reefs and marine biodiversity, the islands have long attracted divers and nature enthusiasts. Officials believe the Guinness World Records recognition could further strengthen tourism in the region and encourage more visitors to explore underwater activities in India.
The twin achievements have now placed the Andaman and Nicobar Islands in the international spotlight, highlighting India’s growing presence in adventure tourism and underwater sports.
