The lake's vibrant color is caused by the reflection of light on the limestone sediments and algae suspended in the clear, spring-fed water.
The park is the center of a successful project to reintroduce the Griffon Vulture to the Eastern Alps.
The Tagliamento River, which borders the reserve, is considered one of the last remaining morphologically intact wild rivers in the Alps.
The reserve sits at the transition zone between the Mediterranean climate and the Alpine zone, leading to unique botanical variety.
The water depth of Lake Cornino reaches approximately 12 meters in some sections.
During the winter, the Griffon Vultures often descend from the surrounding peaks to feed at the designated station, making them easily visible from the observation points.
The Riserva Naturale Regionale del Lago di Cornino is a protected area in Friuli-Venezia Giulia, defined by a glacial-origin lake renowned for its intense turquoise-emerald water. The reserve serves as a primary site for the reintroduction and conservation of the Griffon Vulture (Gyps fulvus) in the Alps. A dedicated feeding station within the park allows researchers and visitors to observe these large birds of prey in a controlled environment. The surrounding landscape consists of karst terrain, scrubland, and woodland habitats carved by the Tagliamento River. Trails wind around the lake and through the rocky hills, providing opportunities for birdwatching and geological observation. The lake is fed by underground springs, maintaining a constant temperature and high water clarity year-round. It is a critical biodiversity hub hosting numerous rare plant species and amphibians adapted to the carbonate-rich water.

Bring high-quality binoculars for birdwatching, as vultures are often seen circling high above the cliffs.
Wear sturdy, closed-toe hiking shoes, as the karst terrain around the reserve is uneven and rocky.
Stay on marked trails to avoid damaging sensitive flora and to keep a respectful distance from wildlife habitats.
Attempting to feed any wildlife; straying off marked paths into restricted conservation zones.
The visitor center and facilities may have reduced operations on weekdays during the winter season.
Maintain silence near the feeding station to avoid disturbing the birds; dogs must be kept on a leash at all times.
