The waterfall is fed by the stream of the Piscia di Ghjaddu, which originates in the higher elevations of the Ospedale massif.
The name 'Piscia di Ghjaddu' translates from Corsican dialect to 'Fir Tree Waterfall'.
The rock face at the site is composed of granite, which has been sculpted into a vertical chute by centuries of water erosion.
Geologically, the area is part of the crystalline basement that forms the backbone of the island of Corsica.
The waterfall is often classified as a 'horsetail' waterfall due to its contact with the cliff face for part of its descent.
Cascade de Piscia di Ghjaddu is the highest waterfall in Corsica, dropping approximately 70 meters from a granite cliff. The waterfall is located within the Alta Rocca region, set against the backdrop of the Ospedale Forest. The site is characterized by a dramatic rock amphitheater formed by volcanic erosion. Water flow is highly variable and depends on regional rainfall, often appearing as a thin veil during the summer months. The surrounding terrain consists of jagged rock formations and dense pine vegetation. The area is managed as part of the regional natural park system. The path to the waterfall involves navigating rocky, uneven terrain characteristic of high-altitude Corsican trails.
The viewing platform located at the top of the waterfall provides the safest and most comprehensive perspective of the descent.
Wear sturdy hiking boots with aggressive tread as the path is steep, slippery, and strewn with loose granite gravel.
Bring more water than you anticipate, as the trail is fully exposed to the sun with very little shade.
Avoid attempting the final descent to the base of the falls if you do not have adequate hiking experience or if the rocks are wet.
Attempting to swim in the pool at the base of the waterfall, as the currents can be dangerous and the water temperature is freezing.
Stay on the marked trail to prevent soil erosion; respect the local flora and fauna; carry out all waste.
