Lac d'Enghien

Lac d'Enghien covers an area of approximately 106 acres (43 hectares) with an average depth of 10 to 16 feet (3 to 5 meters) and features a waterfront promenade lined with Belle Époque architecture and century-old plane trees.

Originally known as the pond of Anguien or Montmorenci, the lake gained prominence after Father Cotte discovered sulfurous water sources with therapeutic properties in 1766, leading to the establishment of thermal baths and spa facilities that attracted King Louis XVIII for treatment in 1821.

The lake has welcomed numerous writers and artists including George Sand, Alexandre Dumas, Jean-Jacques Rousseau, and Ingres, while Mistinguett, one of the most famous performers of the 20th century, was born in Enghien-les-Bains and began her career performing in local cafés before achieving international fame.

Visitors can rent pedal boats and electric boats for approximately 10 to 15 euros per half hour, enjoy free access to the lakeside walking paths year-round, and obtain fishing permits at the local tourist office to fish for pike, carp, tench, roach, and pikeperch in the well-stocked waters.

The lake features a single private island called Île des Cygnes that houses the sailing club and serves as a refuge for diverse bird species including swans, mallards, geese, herons, and families of ducklings during spring migration periods.
