Grotte de la Pontoise is not a show cave cave, but a mostly natural cave open to the public. The cave was developed as much as necessary to make it safe for visitors.
The cave was developed by the Comité Départemental de Spéléologie du Jura, in an agreement with the Parc Naturel du Haut-Jura. The cave is signposted. At the entrance a board with explainatory text was installed. In the six metres deep entrance pit, an iron ladder was installed. Inside the cave luminescent signs help the visitors to find their way.
The visit is not really difficult, but appropriate clothing, good walking shoes, and light (at least two lamps per person) are necessary.
