Wear clothes you don't mind getting dirty, as cave walls and floors leave marks on fabric. Closed-toe shoes with grip are essential for the uneven ground, and since sessions can run up to 3h, bring a light layer for the temperature drop underground.
Getting there
Meet at la grotte du Moudachou, accessible 5 minutes from Arreau: take the D929 past the international campsite, and after the bend look for a bus stop where you can park on the left side of the road while waiting for your guide.
