The best time to visit Tra On Floating Market is in the early morning when the market is at its busiest. The market starts early in the morning and usually winds down by midday. Arriving early will give you the opportunity to witness the lively trading activities and experience the vibrant atmosphere of the market. It is also recommended to visit the market during the dry season, which is from December to April, as the weather is more pleasant and the water levels are lower, making it easier to navigate through the market.
