About RET

Rupantor Eco Tourism Ltd (RET) was born not from a business plan, but from a belief that the Sundarbans deserves to be experienced, protected, and celebrated on its own terms.

In the early 2000s, long before "eco-tourism" became a trend, RET began quietly, without logistics systems or industry support, powered only by passion and a deep conviction in the living culture of the world's largest mangrove delta. Founded by Nazmul Azam David an NGO worker, social activist, and lifelong advocate for the Sundarbans , RET set out to train local communities to welcome visitors not as spectators, but as guests in a living world.

Today, RET operates from its base in Khulna, running responsible, community-rooted cruises aboard its flagship vessel Udaytara. Every member of the team from the captain to the cook, the accountant to the guide is part of a decade-long family that has grown together in service of one shared purpose: to let the Sundarbans speak for itself.

Our Vision

A Sundarbans that endures where responsible tourism becomes a force for conservation, community prosperity, and cultural pride, passed down through generations.

Our Mission

To practice and promote community-based, sustainable tourism in the Sundarbans; empowering local people as custodians of their ecosystem, and offering travelers a genuine, meaningful connection to one of the world's most extraordinary places.
