Grottes des Canalettes, Show cave near Villefranche-de-Conflent, France.

Grottes des Canalettes is a show cave in the Badabany mountain above Villefranche-de-Conflent, in the Pyrénées-Orientales. Its Grande Canalettes gallery, opened for tours, holds tall ribbed columns with bulbous tips, smooth curtain-like draperies lit by warm yellow light, and a floor of short knobby stalagmites beneath thin hanging stalactites. The cave belongs to the Fuilla-Canalettes system, which reached 26,500 metres of mapped passages in 2017.

In 1951 M. Motte noticed a small hole with an air current on the Serrat de les Canaletes; after a year of clearing, the initial shaft was entered. Between 1952 and 1955 the upper galleries and main lower passages were explored and the connection with the Cova de Fullà established, and the owner opened the first section to tourists in 1955. In 1981 Henri Salvayre, Edmond Delonca, Joseph Pujol and Henri Lozano began exploring the network, and in 1982 they discovered the Salle Blanche, which led to the cave being opened to the public.

The cave's name comes from the Canaletes ridge where a small draughty hole was noticed in 1951. The upper level is identified with the Canaletes cave, whose small entrance was the natural access point, while Bastera and l'Os caves were the fossil springs of this level. In summer, classical concerts and a sound-and-light show are held inside the cave.

The entrance of the Grandes Canalettes lies on the road to Vernet-les-Bains, about 300 metres south of Villefranche-de-Conflent. This cave can be visited without a guide from the February school holidays until New Year's Day, and part of the route is accessible to people with disabilities. The smaller Canalettes cave opens only in summer.

One section of the cave hosts classical music concerts and light shows during summer, creating an unusual musical setting beneath the ground. The natural rock formations enhance the acoustic qualities and visual effects of these performances.
