The most traditional way to visit the hortillonnages is by cornet boat, whose flat bottom and raised ends prevent damage to the banks. Quiet and eco-friendly, these boats turn the tour (which lasts about 40 minutes and is limited to small groups) into a meditative journey. As the boat glides along the water, a boatman-guide recounts their history while the vessel slowly moves between the gardens, passing colorful huts, allowing time to observe herons, ducks, or moorhens while listening to birdsong or the sound of the oars.
For several years now, the Hortillonnages have hosted the International Hortillonnages Garden Festival from June to October, where artists, landscape designers, and architects create temporary installations scattered throughout the gardens. Some are accessible on foot, others only by boat, enhancing the immersive nature of the visit. A dialogue between nature and contemporary art offers a poetic perspective on this ancestral landscape.
