5. The Grand Colombier

The highest point of the southern Jura massif, the Grand Colombier offers one of the most beautiful panoramas in the region. At 1,534 meters altitude, this legendary summit is prized by hikers and cyclists who come to challenge its vertiginous slopes.

At the summit, in clear weather, the 360-degree view is simply breathtaking: Lake Geneva, Geneva, the Bernese Alps, Mont Blanc, Vanoise, Bauges, the Belledonne massif, and even the Jura massif unfold before your eyes. The site has several orientation tables to help you identify the surrounding peaks.

For cyclists, the ascent of Grand Colombier is a must, made famous by the Tour de France. The two slopes offer different challenges: the slope from Culoz is renowned for its fearsome gradients (up to 22%!), while the one from Artemare is more regular. In winter, the site transforms into a Nordic domain appreciated by cross-country skiers.

6. The Cerdon caves

A true journey to the center of the earth, the Cerdon caves constitute an exceptional natural site spanning the communes of Labalme and Cerdon. This underground network of 3,700 meters long has been carved by water over millions of years, creating galleries, majestic halls and spectacular geological formations.

The cave visit combines geological discovery and time travel: the site also houses a remarkable prehistoric archaeological deposit. An 80-minute route takes you through the mountain from one side to the other, to emerge in the open air after admiring stalactites, stalagmites and limestone draperies. The constant temperature of 12°C inside offers welcome coolness in summer.

Outside, the prehistoric leisure park allows you to extend the experience with participatory workshops: flint knapping, spear thrower shooting, fire lighting... A fun and educational outing ideal for the whole family.

Perched at over 1,000 meters altitude, the Retord plateau is a true natural balcony over the Alps. This vast expanse of meadows and forests, easily accessible from Lyon or Geneva, offers an exceptional playground for nature lovers and outdoor activity enthusiasts.

In winter, the plateau transforms into a renowned Nordic domain with more than 100 kilometers of cross-country ski trails, marked snowshoe routes, and even biathlon and dog sledding possibilities. The family resort is particularly suitable for beginners and children.

In summer, the plateau reveals other charms: hiking through flowering alpine meadows, mountain biking on numerous trails, climbing on surrounding cliffs, and paragliding to admire the panorama from the air. The biodiversity is remarkable, with preserved fauna and flora that the most observant can discover.

9. Châtillon-sur-Chalaronne

Labeled "Small City of Character", Châtillon-sur-Chalaronne is a charming medieval town located in the heart of Dombes. Crossed by the Chalaronne river and its flowery canals, the town has preserved remarkable architectural heritage that testifies to its rich past.

Stroll through the streets lined with half-timbered houses, admire the 15th-century halls where the traditional market is still held every Saturday morning, and wander along the shaded riverbanks. The remains of ramparts and fortified gates recall the strategic importance of the city in the Middle Ages.

Don't miss the Miniature Train Museum, one of the largest in Europe with more than 200 meters of animated models representing railway life scenes. The former medieval hospital and its 18th-century apothecary are also worth the detour.

10. The Valserine and its gorges

A tumultuous river originating in the Jura massif, the Valserine has carved spectacular gorges in the limestone over millennia. This wild valley offers breathtaking landscapes and remarkable natural sites.

The route along the Valserine reveals several geological curiosities: the losses of the Valserine, where the river disappears into the karst underground, the Devil's Bridge, a natural arch spanning the waters, and the Stone Bridge, a rock formation sculpted by erosion. These sites are accessible by marked hiking trails that wind along the river.

The Valserine is also prized by fly fishermen, who come to tease brown trout in its fast-flowing and crystal-clear waters. The gorges offer an ideal setting for canyoning in summer, with several routes adapted to different skill levels.

12. Lake Sylans

Nestled in a cluse in the heart of Bugey, Lake Sylans is a small natural jewel of glacial origin. This peaceful 17-hectare body of water is surrounded by wooded cliffs that give it a wild and preserved charm.

The lake is a paradise for fishermen, who find there a varied fish population: pike, carp, roach, perch, bream and whitefish. Shore or boat fishing is particularly pleasant in this bucolic setting. Boats can be rented on site to explore the lake and enjoy the surrounding calm.

In summer, the lake also offers swimming opportunities in its refreshing waters. A trail goes around the lake (about 3 km), allowing for a digestive family walk while admiring the reflections of cliffs on the water. The site has picnic areas to extend the day.

13. The Lavours marsh nature reserve

France's largest alkaline peat bog, the Lavours marsh nature reserve extends over 500 hectares at the foot of Grand Colombier. This exceptional wetland houses remarkable biodiversity and constitutes an ornithological site of European importance.

A boardwalk trail of more than one kilometer, accessible to all, allows you to discover this fragile ecosystem without disturbing it. Educational panels line the route and explain the marsh formation, its singular fauna and flora. Observatories and telescopes allow you to admire the many bird species that nest or stopover in the marsh.

Among the emblematic species, you can observe the great bittern, purple heron, marsh harrier, and even the very rare whiskered tern. In spring, wild orchids bloom by the thousands, offering a colorful spectacle to visitors. Guided tours are regularly organized by the reserve managers.

The medieval village of Trévoux, former capital of the principality of Dombes, offers an enriching walk between its castle, its ramparts and its half-timbered houses.
