Come back in November for the water-lily flotilla, not the rice
Boats dressed as lilies, in November
The 2025 edition ran on 22 and 23 November and dates are announced only a few weeks ahead by the site operator, which is also why it is unclear whether it runs every year. This is the answer to when Ninh Binh is not full: the autumn bloom is largely a domestic-visitor season while foreign itineraries treat Tam Coc as a June destination. Thai Vi temple sits on the walking route between Tam Coc and Hang Mua, so you can reach the blessing on foot if the wharf is heaving. Cool and often drizzly, which is the trade for having the valley to yourself.
