Discover Romagnieu

Explore Romagnieu through a range of interests: the route of the GR 65, the Étang des Nénuphars nature area, swimming and leisure activities at O’lac, and historic buildings. There are practical differences too: activities at O’lac are charged according to different time units, while a reservation is required for a guided tour of the Chapelle Saint Hilaire d’Avaux.

Swimming and leisure at O’lac

O’lac offers supervised swimming from 10 a.m. to 7 p.m. Facilities include a landscaped beach, water games and a diving tower. If you want to compare different activities, you’ll find options both on the water and on land, including mini golf and tennis.

Stand-up paddleboards and pedal boats each cost €8 per 30 minutes. Rosalies for a ride around the lake are also available to rent for €8 per 30 minutes. A mini-golf round costs €4 per person; the price for a tennis court and equipment is €10 per hour for two people. The billing unit therefore depends on the activity: half an hour, a round per person, or an hour for two people.

Étang des Nénuphars: nature close to the town centre

The Étang des Nénuphars is a natural area of about 14 hectares, close to the centre of Romagnieu. It has been part of the Isère department’s ENS network since 2003. The area is open every day throughout the year and admission is free. Check the latest access conditions before your visit.

The pond provides a habitat for the Desmoulin’s whorl snail, which is threatened with extinction in Europe. The snail lives there among clumps of sedge (Carex) and in the surrounding waters. The natural area is therefore defined not only by its location and size, but also by the specific habitat it provides for this endangered species.

The GR 65 and the surrounding area

The GR 65, the Chemin de Saint-Jacques de Compostelle, passes through the communes of Aoste, Romagnieu and Les Abrets en Dauphiné in Isère, then continues via Saint-Ondras and Valencogne. Romagnieu is therefore part of the route described for this long-distance trail. The trail is a distinct point of interest alongside the natural area and the village’s historic buildings.

Churches, houses and former uses

Romagnieu’s church dates back to the 11th and 12th centuries. The local heritage also includes the houses known as dauphinoises. Their thick rammed-earth walls and hipped roofs covered with overlapping tiles are distinctive features of this architecture. Together with the church, these houses showcase different aspects of local heritage: sacred architectural history and characteristic house styles.

The Forges de la Massotte tells another story of conversion to a new use. The former shovel factory has now been converted into an inn. The focus here is the change from its former industrial use to its current use as an inn.

The Chapelle Saint Hilaire d’Avaux is a former medieval church dating from before the 12th century. It is surrounded by an old cemetery and houses listed objects. Guided tours for groups of 5 to 20 people are available throughout the year by prior reservation; each tour lasts one hour. Check the visiting arrangements in advance, as they may change.

In Boutey, worked limestone blocks remain as the foundations of a bridge that connected Augustum (Aoste) with Lemencum (Chambéry). The blocks are especially visible when the water level is low. The water level therefore affects when these surviving structural elements can be seen.
