Lac de Narlay is a captivating glacial lake nestled in the heart of the Jura Mountains, within the Jura department of France. Situated at an elevation of approximately 748 meters in the municipality of Le Frasnois, about 10 kilometers south of Champagnole, it is a prominent feature of the Franche-Comté region. This triangular-shaped lake is renowned for being the deepest of the Jura lakes, reaching up to 40 meters, a characteristic that has earned it the evocative nickname "the black lake" due to its dark, profound waters. It forms part of the picturesque "four lakes" area, alongside Lac d'Ilay, Petit Maclu, and Grand Maclu.
What truly draws visitors to Lac de Narlay is its serene natural beauty and tranquil atmosphere. Hikers and nature lovers consistently praise the idyllic setting, with its pristine waters surrounded by dense forests, alpine meadows, and limestone cliffs. The opportunity to walk a charming path that encircles the lake, offering spectacular views of the water and the wild, unspoiled landscape, is a particular highlight for many. The blend of natural splendor and opportunities for low-impact recreation makes it a cherished destination in the Jura region.
Before visiting, it's helpful to know that a signposted path winds around the lake, providing an accessible way to explore its shores. While the path can be narrow in places, it generally offers a pleasant walk through forests and meadows. Swimming is permitted in Lac de Narlay, making it a refreshing stop on warmer days, though visitors should be aware of any voluntary tranquility zones or temporary prohibitions put in place to protect local wildlife. The lake's location on the second plateau of the Jura massif means the terrain is generally gentle around the immediate shoreline, but surrounding trails can offer more varied challenges.
Lac de Narlay is an excellent destination for various outdoor activities, particularly walking, hiking, and angling. The circular walk around the lake is a popular choice for those seeking a peaceful stroll. For more extensive adventures, the lake is part of a larger 12-kilometer trail that connects the "four lakes," offering panoramic views from nearby viewpoints like Pic de l'Aigle and Belvédère des Quatre Lacs. Fishing for trout and perch is also a favored pastime here. The area is particularly beautiful during spring and autumn when the foliage changes, though summer offers ideal conditions for swimming and picnicking.
Visitors often share vivid details of their experiences, from the peacefulness of walking along the lake's edge to spotting diverse aquatic fauna in its clear, dark waters. The sense of being immersed in a wild, protected environment, recognized as a Natura 2000 site and part of the Ramsar Convention's "Peatlands and Mountain Lakes of the Jura" network, adds to the profound connection many feel with this place. The local legends, such as the tale of the "black lake" being formed by a vengeful beggar woman, also add a mystical charm to the visit.
