Lighthouse of La Coubre

The La Coubre Lighthouse rises on the Pointe de la Coubre, a few kilometers from La Tremblade on the Charente-Maritime coast in France's Nouvelle-Aquitaine region. At 64 meters tall, it is the tallest lighthouse along this stretch of coastline and one of the landmark sights of the Royan area.

Where did the lighthouse come from?

A warning light has guided sailors past this dangerous headland for centuries. A fire beacon already burned here in 1690. The first proper lighthouse, built of wood, was lit in 1860, and in 1895 it was replaced by a stone tower positioned about 1.5 km from the shoreline. Shifting dunes and relentless coastal erosion soon made clear that the stone structure would not last — it eventually collapsed in 1907.

Anticipating exactly this, authorities had already decided in October 1904 to build a sturdier replacement, set back 1.8 km from the coast. Work moved fast: the new tower entered service on October 1, 1905, just months before its predecessor gave way.

What makes this tower stand out?

La Coubre was the first lighthouse in France ever built in concrete, a material still viewed with suspicion by engineers at the time. The design came from engineers Alexandre and Modelsky, who gave the tower a cylindrical, slightly tapering "trumpet" profile. Inside, a spiral metal staircase was fabricated in the workshops of Gustave Eiffel — the same engineer behind the Paris tower.

How do you get there?

The lighthouse stands in a pine forest on the Pointe de la Coubre, a short drive or bike ride from central La Tremblade, reachable via a popular cycling route that winds through the Coubre forest. The area is part of a wider band of dunes and woodland stretching down to Ronce-les-Bains, which makes cycling a comfortable and common way to reach the site, especially in summer.

What will you see, and what does the climb involve?

Reaching the top means climbing 300 steps up a winding metal staircase — a real workout, but one rewarded with a sweeping view over the Gironde estuary, the ocean, the dunes, and the pine forests stretching inland. The lighthouse is still an active navigational aid: its Fresnel-lens beam carries roughly 28 nautical miles, about 52 kilometers.

At the foot of the tower, a small museum devoted to the history of the site's earlier lighthouses has welcomed visitors since it opened in July 2005. It's a good stop before tackling the stairs — or an alternative for anyone who'd rather skip the 300 steps — to learn about the structures that stood here before the current tower.

When is the best time to visit?

The lighthouse and its surrounding forest are open year-round, but spring and summer are the most comfortable seasons, when longer days and steadier weather suit both the climb and longer walks or bike rides through the nearby woods. Expect heavier foot traffic during the summer season, particularly on weekends.
