A special attraction in Crissolo is the Rio Martino grotto. It is about 10 minutes walk from the beach La Spiaggia, a small reservoir of the Po. The underground path system of the Grotto San Martino extends over several floors. The lower arm is easily accessible and ends at a waterfall 40 m high.
The cave can be explored on foot without any special equipment. On the attractive tour you can see stalactites and stalagmites, with significant chromatic variations. At the end of the tour there is a spectacular waterfall. Here you will be glad to have carried the torchlights and a rain cape standing in the spray of the waterfall smashing into a lake in the cave. Humidty 100%, temperature 5C.
