Duncan Passage, Maritime strait between South Andaman and Little Andaman, India
Duncan Passage is a strait between island groups in the Andaman archipelago, stretching about 48 kilometers across. It lies between Rutland Island to the north and Little Andaman Island to the south, with waters deep enough for safe maritime traffic.
The strait received its name during British colonial rule in India. It grew to become an important maritime route for regional shipping and trade in the Indian Ocean region.
Fishing communities from the Andaman Islands use these waters regularly for their livelihoods and to connect island settlements. The passage has shaped how people travel and trade between different parts of the archipelago.
The waters maintain sufficient depth throughout for boat traffic and remain navigable year-round. Visitors can explore the area by boat tours from nearby islands or watch maritime activity from the shorelines.
Several small islands scatter throughout the passage, including North Cinque, South Cinque, and Passage Island among others. These rocky formations create a distinctive seascape and provide habitats for dolphins and seabirds.
