The lighthouse is located at the exact geographic point where the Somme River meets the English Channel.
The sandbanks exposed at low tide are the primary gathering spot for the largest seal colony in France.
The lighthouse has a flash cycle characterized by a sequence of white flashes, visible from significant distances at sea.
The coastline at Le Hourdel is geologically unstable, leading to the historical need for coastal erosion defense measures.
The site offers views across the bay toward the medieval town of Saint-Valery-sur-Somme.
Phare du Hourdel is an active lighthouse situated at the mouth of the Somme estuary in Cayeux-sur-Mer, France. The white tower features a distinct black lantern room and serves as a navigational beacon for the maritime traffic entering the bay. It is located at the extreme point of the Hourdel headland, where the coastline transitions between sandy beaches and pebble banks. The area is renowned for its large colony of harbor and gray seals that haul out on the sandbanks at low tide. The lighthouse itself is not open for public interior tours, but the surrounding grounds provide a panoramic view of the Baie de Somme. The landscape is characterized by shifting tidal flats and salt marshes, making it a critical habitat for migratory birds. The structure remains a functional navigational aid managed by French maritime authorities.

Bring binoculars to observe the seals on the sandbanks from a respectful distance.
Check local tide tables before visiting, as the bay's landscape changes drastically between high and low tide.
Wear sturdy footwear suitable for walking on loose pebbles and potentially muddy shoreline paths.
Do not attempt to walk out onto the sandbanks to reach the seals, as the incoming tide in the Baie de Somme is notoriously fast and dangerous.
