The Parc Floral de la Source is a large botanical garden and park on the southern edge of the city, built around the natural spring that is the source of the Loiret. Laid out for the 1967 International Flower Show, it covers about 35 hectares and contains formal French gardens, rose collections, an iris garden, and areas of more naturalistic planting around the waterways.
Spring and early summer — April through June — are the best times to visit, when the rose garden and iris collection are in bloom. The park also has a small train for children, flamingos in the waterways, and areas of woodland good for a picnic. It is about 7 km from the city centre, reachable by tram.
