The pools are carved into the limestone bedrock by the mechanical action of pebbles swirled by the river current over millennia.
The water in the Pozzo della Madonna remains notably cold even during peak summer months due to the high altitude of the source.
The Serra river basin is part of the larger Apuan Alps Regional Park, a protected area known for its unique geological formations.
The site is prone to flash flooding, leading local authorities to restrict access during periods of heavy rainfall.
Polle di Malbacco - Pozzo della Madonna is a series of natural turquoise swimming pools carved into the rock along the Serra river in the Apuan Alps. The Pozzo della Madonna is the most recognizable basin, known for its deep emerald waters and a natural rock slide created by water erosion. The site is located within a forested landscape featuring large limestone boulders and slippery terrain. Water temperatures remain consistently cold due to the mountain spring source. Access to the pools requires navigating steep, unpaved forest trails. The area is susceptible to sudden changes in water flow after rainfall.

Wear sturdy water shoes with high grip to manage slippery, moss-covered rocks.
Bring a waterproof bag for electronics, as there are no dry storage lockers available.
Pack out all trash, as the area has no waste disposal services.
Attempting to jump from high rocks into the pools, as the depths vary significantly and submerged boulders present severe injury risks.
Access may be restricted by local municipal ordinances during dry seasons to prevent fire hazards or in rainy seasons due to flood risks.
Practice leave-no-trace principles; avoid using chemical sunscreens that contaminate the small, contained bodies of water.
