Dubla Rash Mela is not only a big fair for Bagerhat, it is undoubtedly one of the biggest fairs in the country. At the centre of the festival are twenty thousand temporary fishermen, who are engaged in catching and drying fish on Dubla and nearby islands. Every year in the Bengali month of Agrahayan, the fair continues for 5-7 days during full moon time.
Dubla island stands on the Bay of Bengal and is a part of the Sundarban Forest. The fair on Dubla island started in 1923, by Hari Bhajan, a disciple of Thakur Hari Chand. This has become a grand occasion for many foreign tourists visiting the Sundarbans and people come from India as well. Around 40-50 thousand people join the celebrations every year. Handicrafts and precious wooden items are put on sale.
