The dive

An underground river in Sainte-Néomaye, near Niort. Practical: the pin is approximate: the centre of the commune.

Long section with ~20 cm of air above water and mud, and a vertical squeeze where you must take off your helmet. In 2019 a rusted anchor broke on the way out: do not trust fixed ropes or bolts.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from public sources: plongeesout (FFS), Wikipedia, the FFS congress page on the Touvre (2009), FFESSM Subaqua (2018), the Spit Club Saint-Maixentais, CDS 79, BRGM (1974), the communes of Touvre and Magnac-sur-Touvre, Rivières de l'Angoumois, ABIMES, GESMA, the La Rochefoucauld caving club (ARSR), the FFESSM Nouvelle-Aquitaine club directory and MedSubHyp (September 2026), and for Le Paradis Blanc Divernet (2016), Aquatek and the Charente prefecture (Oct 2026). Much of the dive data is old (1951–2019) or comes from a single club report. Pins only from published coordinates (Gros Roc); the Touvre springs and the Sources du Cros from OpenStreetMap; the three Deux-Sèvres sites approximately at the centre of their commune (CDS 79, message, Oct 2026); the Glane from Grottocenter; one spring and Le Paradis Blanc have no pin yet. ~ = estimate.
