About
Regnéville harbor is an estuary formed by the mouths of 2 rivers: the Sienne and the Soulles. Le Havre is separated from the sea by the Pointe d'Agon nature reserve. Classified since 1989, it is also a Special Protection Area for its high ornithological value and has been declared a Site of Community Importance since 2004. This natural area of ecological, flora and fauna interest also serves as a beaching port. Regnéville harbor is the largest of the Cotentin harbors, and can be crossed at low tide (with associations, too dangerous alone) to reach the Pointe d'Agon site. Here you can admire the majestic scenery, the rich flora and fauna, and the views of the Château de Regnéville and the Pointe d'Agon lighthouse.
