Character of Lantouy
Gouffre de Lantouy lies hidden in a wooded setting near Saint-Jean-de-Laur. Beneath the calm spring pool, the cave gains depth relatively quickly. The available survey shows a route via approximately -9, -15 and -25 metres to the deeper section around -40 to -51 metres.
At around -25 m, a sand obstruction is indicated. Farther on, around -45 to -47 m, étroitures — restrictions — are marked. The known survey ends at approximately -51 m.
Note: the ±100 m development is currently an estimate based on the available survey and will be updated when a reliable measured length becomes available.
