Olonzac: Canal du Midi, history and walking routes

Olonzac brings together the Canal du Midi, archaeological heritage, and opportunities for walks and hikes. When choosing a destination, you can weigh up a stay focused on culture and the history of water engineering, a multi-stage hike, or time at Lac de Jouarres. The canal runs south of the town; the lake is near Olonzac, between Carcassonne and Narbonne. The different places and activities provide concrete ideas for planning your trip.

At the Canal du Midi: structures and boats

The Canal du Midi structures at the Ognon include double locks, an aqueduct bridge, a defensive gate, and spillways. These different structures shape the canal’s historic character. They are part of a protected area on the World Heritage List. The canal in Olonzac therefore offers both a connection to the history of water engineering and a place to observe the riverbank.

In Olonzac, you can stroll along the banks of the Canal du Midi. You can also watch boats pass through the double lock at the Ognon. A walk along the canal and watching boats pass through the lock offer different perspectives: when walking, the focus is on the path along the bank; when watching, it is on the boats moving through the lock. You can consider these experiences as separate interests for your stay.

Archaeology and local history

The Centre de Recherche et de Documentation du Minervois in Olonzac has archaeological collections featuring finds from the Palaeolithic to the Roman period. Anyone interested in the region’s history will find a broad span of time represented in a single collection. One-hour guided tours or self-guided visits are available on request. The Centre also offers public and school programmes, including archaeological outings, talks, and mosaic and ceramics workshops. The programme formats may change.

You will also encounter different historical points of reference beyond the collections. Mourrel Ferrat lies on the southern boundary of the municipality of Olonzac and is a protohistoric site from the Iron Age. The Oppidum de Bassanel dates from the 6th century BC. These two sites relate to different archaeological contexts and periods. In Olonzac’s historic centre, you can discover the winegrowers’ houses on a stroll; here, the focus is on the town’s traditional architecture.

Hiking and planning your stages

The Tour en Minervois on the GR® de Pays Minervois, Saint-Chinian, Faugères is a 38-kilometre circular hiking route for which Olonzac is a designated reference point. A three-day itinerary is suggested: from Olonzac to La Caunette, on to Mailhac, and back to Olonzac. The start of the tour follows the GR® 77 and is marked in red and white. Routes and markings may change; check conditions before setting out. Accommodation availability can also change, so it is advisable to check in advance when planning your stages.

If you would rather plan a single walk, the historic centre and its winegrowers’ houses make a good focus of their own. The circular route and the town-centre walk differ in length and character: the tour is proposed as a multi-day sequence of stages, while the walk focuses on the houses in the centre. This lets you plan your time in Olonzac according to whether you are looking for a multi-stage hike or a shorter cultural experience.

Lac de Jouarres and the market in Olonzac

Lac de Jouarres is near Olonzac, between Carcassonne and Narbonne, and covers about 110 hectares. The lake has areas shaded by pine groves, as well as pebble and grass beaches. The beaches are supervised in summer. Activities mentioned include inflatable games, stand-up paddleboarding, windsurfing, hiking, and fishing. The options range from water activities to spending time on land. Supervision and facilities may change; check conditions before your visit.

A regular event in town, the Olonzac market is held every Tuesday morning. It adds a fixed weekly rhythm to trips to the canal, archaeological sites, and the nearby lake. When planning your stay, you can take this market into account alongside the suggested hiking days and visits to Lac de Jouarres.
