From the thermal baths, continue south to Place Henri IV, then take the stairs on the left, cross the road, and continue through the top of the village on the right, then straight ahead to the start of the path. When you reach the track, turn left in the direction of the climb. Cross the bridge and leave the track about 100m further on, by the path on the right in the bend. Then continue straight on to the Grotte des Eaux-Chaudes, following the signs.
CAUTION: DANGER OF FALLING ROCKS: DO NOT VENTURE INTO THE CAVE. THANK YOU TO RESPECT THE PLACE.
