12 tours available in Ariège, from 38 € to 200 €, covering sessions of 3h to a full day. Three physical levels structure the offer. "Everybody welcome" tours (42 € and 45 €) are the right entry point: no prior experience needed, 3h underground in caves like the Ermite or Siech. "Occasionally sporty" tours (38 €,90 €) cover the widest range, from half-day cave circuits to the Vicdessos underground river at 55 €, and the full-day Eaux Chaudes Chasm at 90 €. "Sporty" tours demand real effort: the Siech cave at 43 €, the Vicdessos underground river at 43 €, and the Sakanie chasm at 73 € for 5h. The Port de l'Hers Chasm at 200 € is the top-end pick, a full day at sporty level. Your decision comes down to one question: how deep do you want to go?

Operators provide helmets, headlamps and caving suits for all tours, but wear thermal underlayers for multi-hour sessions, especially on underground river tours where water contact is expected. For full-day sporty outings like the Eaux Chaudes Chasm or Port de l'Hers Chasm, bring a change of dry clothes for after.
