From the parking lot there’s a steep 90-minute footpath. Make sure to bring a good headlamp or flashlight because this trip involves some cave spelunking. There are three grottoes along this path. The upper grotto consists of mostly long tunnels. While the lower grotto is 40 m long and shaped like a «S». At the end of this one you’ll arrive at a beautiful waterfall plunging 14 meters down into a white marble basin. I would recommend mountain shoes, or they should at least be waterproof since the cave floor is often wet. You can get another angle of the waterfall’s journey into the lower grotto from the one in the middle.
