This trail is classified as difficult and requires a good level of physical fitness, surefootedness, and appropriate mountain footwear. Hikers should be prepared for significant altitude gain, exposed sections, scrambling, and potentially slippery paths with unstable rocks, especially between Lake Trona and Lago dell'Inferno. Some parts might even require mountaineering experience or specific equipment.
While the exact parking location in Introbio isn't specified, Introbio serves as the starting point for this circular route. You would typically look for public parking areas within the town to begin your trek. Consider arriving early, especially on weekends, to secure a spot.
Generally, dogs are allowed on trails in the Orobie Alps, but they should be kept on a leash, especially in areas with wildlife or near refuges. It's always a good idea to check with the specific refuge, like Rifugio FALC, regarding their policy on dogs inside the hut.
The best time to undertake this challenging hike is typically from late spring to early autumn (June to September) when the snow has melted, and the weather is more stable. Always check the local weather forecast before you go, as conditions in the high mountains can change rapidly.
No, there are no specific permits or entrance fees required to hike this trail within the Parco delle Orobie Bergamasche. However, always respect local regulations, stay on marked paths, and practice Leave No Trace principles to preserve the natural environment.
The terrain is highly diverse. You'll encounter alpine hiking paths, secondary roads, and regular hiking paths. The initial stretch from Introbio might be an easy dirt road, transitioning into a forested area with steps and roots. As you ascend, expect rocky sections, scree, and potentially areas equipped with chains for assistance. The most challenging parts often feature slippery surfaces and unstable rocks.
This route offers numerous highlights. You'll pass by the Madonna della Neve refuge and church, the Santa Rita Mountain Hut, and the iconic Rifugio FALC, known for its authentic atmosphere and homemade food. A major natural highlight is the Lago dell’Inferno Dam and the stunning alpine lakes, including Lago di Trona and Lago dell'Inferno itself. Keep an eye out for unique rock formations like "la sfinge" and panoramic views of the Orobie Alps.

You'll also briefly encounter sections of the Alta Via della Valsassina - Tappa 3 and the Rifugio Trona Soliva - Rifugio F.A.L.C. trail.
Yes, Rifugio FALC is a mountain hut that offers accommodation. It's a charming place to rest, enjoy warm hospitality, and savor delicious homemade food. Given the trail's length and difficulty, an overnight stay can be a great way to break up the hike or extend your mountain experience. It's advisable to book in advance, especially during peak season.
The wild environment of the Orobie Alps offers opportunities to spot local wildlife. Hikers might encounter ibex, known for their impressive horns and agility on rocky terrain, and marmots, often seen basking in the sun or heard whistling warnings. Always observe wildlife from a respectful distance.
Introbio is accessible by public transport, typically via bus services connecting it to larger towns in the Valsassina valley or train stations like Lecco. It's recommended to check local bus schedules (e.g., Lecco Trasporti) in advance, as services might be less frequent on weekends or during off-peak seasons.
Given the trail's difficulty and varied terrain, essential packing includes sturdy hiking boots with good ankle support, layers of clothing suitable for changing mountain weather, waterproof outer shell, sufficient water (at least 2-3 liters), high-energy snacks, a map and compass/GPS, first-aid kit, headlamp, and sun protection. Trekking poles are highly recommended for stability on steep and rocky sections.
