The island is accessible by a unique amphibious vehicle that drives across the sandbar at low tide.
Tatihou was designated as a UNESCO World Heritage site in 2008 as part of the 'Fortifications of Vauban' series.
The lazaret was built in 1720 as a direct response to the Great Plague of Marseille, ensuring regional maritime safety.
The island serves as an important migratory stopover for thousands of seabirds, supported by the site's bird sanctuary status.
Archaeological excavations of the bay have recovered significant naval wreckage from the 1692 Battle of La Hougue, some of which is housed on the island.
The gardens on the island feature a collection of plants specifically adapted to the salty, wind-swept maritime environment.
The Lazaret de Tatihou is a historic quarantine station located on Tatihou Island off the coast of Saint-Vaast-la-Hougue, Normandy. Originally constructed in the 18th century, the facility served as a maritime lazaretto to prevent the spread of infectious diseases from incoming vessels. The site includes a series of stone buildings designed to isolate crew and cargo during outbreaks of plague or cholera. It is part of the larger Tatihou site, which also features a Vauban tower listed as a UNESCO World Heritage site. The architecture reflects the defensive and medical requirements of the period, situated within the context of the nearby 1692 Battle of La Hougue. The island itself is an ecological zone managed by the Conservatoire du littoral. Restoration efforts have preserved the site's layout, maintaining the integrity of its historical maritime function. Visitors can explore the grounds, which serve as a maritime museum and research hub today.

Check the tide tables in advance, as the island is only reachable by an amphibious boat or a long walk across the sand when the tide is low.
Bring sturdy footwear, as the terrain consists of sandy paths and uneven stone walkways.
Plan your visit to coincide with a high tide if you intend to use the shuttle boat service, as the boat cannot operate during extreme low tides.
Do not attempt to walk across the sandbar without checking local tide charts, as the incoming tide can isolate walkers unexpectedly.
The site typically operates seasonally, closing for the winter months; the amphibious boat service schedule is strictly dependent on daily tide levels.
Strictly follow marked paths to protect the sensitive bird nesting zones and botanical garden areas.
