Île Milliau, Tidal island in Trébeurden, France.
Île Milliau is a tidal island off the coast of Trébeurden in Brittany that can only be reached on foot at low tide. The terrain mixes moorland, ferns, and low coastal shrubs crossed by old footpaths, making it one of the more varied stretches of natural land in the area.
The island holds Ty Liac'h, a Neolithic gallery grave built from upright stones and horizontal slabs that shows this coast was already inhabited thousands of years ago. Over the centuries, the island later became a place of Christian devotion linked to local saints.
The island is named after Saint Miliau, a Breton martyr from the 6th century whose story has stayed alive in the region. Visitors today still encounter his name on local signs and hear his legend from people living along this stretch of coast.
Access is only possible at low tide, so checking the tide times before setting out is important to avoid getting stranded. Sturdy shoes are a good idea since the crossing involves sand and wet ground before reaching the footpaths on the island itself.
In the early 20th century, Lucie Jourdan had a private villa built on the island, which was later requisitioned during the German occupation in World War II. The building still stands today and is one of the few man-made structures on an otherwise natural stretch of land.
