Tourist Night, which began in the Le Havre Agglomeration in 2013, extended to the whole Seine estuary in 2018.
Ten intermunicipal authorities within the Metropolitan Pole of the Seine estuary and the region’s tourist offices offer more than 50 free tours and activities to develop and promote the area.
In 2021, the Estuary Tourism Nights will extend throughout the month of October: from October 2 to 23, on Saturdays from 5 p.m., churches, museums and cultural sites imagine a special program accessible to all free of charge.
