The Rio Ramato small valley is among the areas of greatest natural value in the Park due to the presence of rare species such as the snowdrop. The name "rio" (meaning river) comes from the presence of a ferruginous spring flowing from the rocks, the water is called "copper water" due to the color deriving from the presence of iron oxide and iron oxide-hydroxide.
The itinerary No. 3 "Rio Ramato" climbs down through the forest in the cool and damp valley bottom.
