La Grotte de l'Observatoire 
Description
This cave is located at the bottom of the Jardin Exotique and descends down into the cliffs below. Starting at 104m above sea level you descend around 300 steps to the bottom of the visitable cave at around 50m above sea level. Along the way there are stunning stalactites and stalagmites and lots of other curious rock formations that have been created by the constant dripping water over the millennia. It should be noted that at the end of the tour it is a direct climb up around 250 steps from the final gallery back up to the surface, so it is quite a strenuous visit.
