The river's distinct turquoise color is the result of 'calcare' (limestone) deposits suspended in the water.
The trail features the 'Diborrato' waterfall, the largest cascade along the river course.
The river was historically used to power paper mills and grinding mills in the medieval period.
The Sentierelsa is part of a larger network of paths integrated into the Via Francigena pilgrimage route.
The water contains high levels of travertine-forming minerals that coat the submerged rocks.
The Sentierelsa Trail is a 4-kilometer trekking path running along the Elsa River within the Parco Fluviale dell'Elsa in Colle di Val d'Elsa, Italy. The trail is defined by its turquoise, mineral-rich waters caused by high concentrations of calcium carbonate. The path follows the riverbank from the bridge at Spugna to the bridge at San Marziale. Hikers pass through forested terrain featuring small rapids, cascades, and white limestone cliffs. The route connects the historic upper town of Colle di Val d'Elsa with the surrounding rural valley. The trail is maintained as an environmental park to preserve the biodiversity of the riparian ecosystem.

Wear sturdy, water-resistant hiking shoes as the path can be muddy near the riverbanks.
Bring mosquito repellent, as the humid, forested river environment attracts insects during warmer months.
Pack a reusable water bottle as there are limited facilities directly on the trail.
Attempting the trail immediately after heavy rainfall, as sections can become slippery and flooded.
Respect the protected environment by staying on marked paths and carrying all waste out of the park.
