Nantua Lake Park

A preserved natural haven in the heart of nature

The Nantua Lake Park, located in the Ain department, is much more than just another nature tourism site: its crystal-clear waters, magnificent limestone cliffs, and wooded shores create a landscape rarely seen in the Haut-Bugey region. Designated a Sensitive Natural Area, this glacial lake covers a remarkable 141 hectares and provides a refuge for local flora and fauna, making it an ideal spot for walks or mountain biking while admiring the view. The dry meadows and groves of this regional natural park are home to wild orchids such as the marsh gladiolus, rare butterfly species like the Apollo, and a diverse birdlife including kingfishers and peregrine falcons, making it a favorite destination for wildlife enthusiasts. A visit to the Nantua Lake Nature Park offers a glimpse into another world: less noise, more nature, and breathtaking panoramas.

Water sports: swimming, paddleboarding, and sailing for all levels

In summer, the lake transforms into a veritable playground for numerous water-based tourism activities. Several supervised swimming areas allow visitors to enjoy clear, refreshing water, while rental companies offer paddleboards, pedal boats, and kayaks for exploring the lake at your own pace. Sailboats and dinghies also find their place on this body of water, which is particularly popular with families and beginners thanks to several suitable courses. Rental options are generally offered for half-days or full days; prices remain reasonable but vary depending on the season and equipment. For the more athletic, a paddleboarding session at sunrise offers a contemplative and often tranquil experience.

Fishing at Lake Nantua – an exceptional spot for a diverse range of fish

As mentioned above, Lake Nantua, of glacial origin, covers approximately 140 to 147 hectares, with a maximum depth of around 50 meters, making it the largest natural lake in the Ain department. This also means a very wide variety of fish, making it a prime fishing spot in the Nantua area, as well as a leading destination for nature and water tourism.

A wide variety of fish species at Lake Nantua

Its crystal-clear waters teem with numerous fish species: a rich marine life that appeals to fly fishermen as well as pike and carp anglers. Among others, you’ll find:

Perch — the most common species, often caught along the banks or vertically around the weed beds.

The pike—the lake’s apex predator, prized for its powerful fight.
The renowned lake trout, sometimes quite large, which can be caught using lures or nymphs.
Zander—present, though less abundant than perch or pike, for anglers who enjoy predatory fish.
Carp—especially during night fishing sessions in specific spots.
And also various other whitefish and “whitebaits”: bleak, roach, bream, tench, chub, and whitefish, which are part of the lake’s fish population.
Why is Lake Nantua a good fishing spot?

Fish diversity: Thanks to the coexistence of predatory fish (pike, zander, perch) and bottom-dwelling or “white” species (carp, roach, bream, whitefish, etc.), the lake offers opportunities for numerous techniques—casting, lure fishing, sliding rigs, night fishing, etc.

Varied depth and topography: With depths reaching up to 50 m, certain species like lake trout or whitefish can be found at greater depths—ideal terrain for vertical jigging or bottom fishing.
Night carp fishing: For those who enjoy calm night sessions, a dedicated area exists, making the lake a popular spot for carp anglers.

A magnificent natural setting: Mountains surrounding the lake, clear waters—the environment itself enhances the pleasure of fishing, beyond the catch.

In practice, whether you’re drawn to the thrill of a pike fight, the subtle pursuit of a lake trout, or the patience of a carp line, Lake Nantua stands out as a prime destination for anyone wanting to observe its fish population. It combines a rich ecosystem, diverse landscapes, and a pristine natural setting, making it ideal for any successful fishing trip.

High-altitude ridges and trails: spectacular views of the Bugey region guaranteed!

Beyond the loop around the lake, more challenging routes and wild trails start from the surrounding ridges, offering breathtaking panoramas of the lake and the Bugey valleys. These trails, sometimes rocky and more technical, reward the effort with stunning views of the limestone cliffs and mosaic meadows.

They are particularly attractive in spring and autumn, when the light accentuates the contrasts and the vegetation changes color, revealing the full splendor of the mountain ranges. Experienced hikers will find routes here for a half-day or a full day, with the option of combining a return along the water’s edge for a change of scenery.

Nantua’s Heritage: Between History, Abbey, and Local Culture

A visit to the park naturally includes a stop in the town of Nantua, a small town with a rich history, far removed from the wild charm of the lake. Saint-Michel Abbey, the old streets, and the local museum lend a pleasant heritage feel to the walk. The accessible and marked “Discover Nantua” trail invites you to explore the shops and the Doye spring, while the Resistance Museum provides a strong historical dimension for a better understanding of the area. This blend of nature and heritage gives the stay real depth: you don’t just come for swimming, but also to feel the human imprint that has shaped these landscapes, near the Jura Mountains.

Local Flavors and Cheeses: A Well-Deserved Gourmet Break!

After a day of hiking, a delicious meal is in order. Nantua and its surroundings offer a variety of shops and restaurants where you can truly savor local specialties: quenelles with Nantua sauce, dishes featuring local cheeses, and generous portions. Markets and some small grocery stores offer Bugey products—farm cheeses, charcuterie, and artisanal breads—perfect for a picnic on the lake shore. As for prices, the restaurants around the lake offer a range of options to suit family budgets, with daily specials, set menus, and à la carte choices. It’s advisable to check prices and make reservations during peak season.

A gourmet stop at the Seignemartin cheese shop in the heart of Nantua?

To extend your exploration of the lake, visit the Seignemartin cheese shop at 350 rue de la Gélinotte: a local favorite where the cheese platters are simply irresistible. Here, the wheels and pressed cheeses reveal all the beauty of the Bugey terroir: mountain tommes, small farmstead gems, and aged selections that pair perfectly with a quenelle or a glass of local wine. The place exudes a warm, artisanal atmosphere: you’ll find tasting advice, portions to take away for a picnic by the lake, and often new seasonal offerings. An ideal visit to taste authentic local products and take home a gourmet souvenir of Nantua, all while admiring the vineyards of the Rhône-Alpes region.
