WHY THIS HIKE
Oropa and the Rosazza Tunnel
Above Oropa there is a tunnel dug by hand in 1897 to link the sanctuary with the Cervo valley: 400 metres through rock, dark, water dripping. Walking through it by torchlight and coming out on the other side, above Rosazza, is the moment everyone remembers from this loop. The rest is beech wood, pastures and the view over the plain.

Come alone, leave with new friends
The experience
From the Oropa Sanctuary we climb the old dirt road to the mouth of the Rosazza Tunnel at 1,480 m. We walk through it and look out over the Cervo valley, the stone houses of Rosazza below.
We return on the Oropa side by woodland trail, with a lunch stop on a meadow or at an inn. At the end, the sanctuary and its basilica.
Headlamp required: the tunnel is dark and wet. Packed lunch or, by reservation, polenta at an inn in Oropa. In late November we start early for the light.
The Oropa Sanctuary is an hour and forty from Milan: A4 to Carisio, then Biella and the Oropa road. Free, large sanctuary car park. Car pooling in the outing's Telegram group.

Easy
Perfect for those who want to enjoy nature without too much effort. Short, well-marked trails with gentle slopes. No technical difficulties, just a desire to walk, breathe in the fresh air, and share the day with a group.
Ideal for: Beginners, families, those who want to take their first steps in trekking.
Easy Plus
A little faster pace, but still accessible. Slightly longer routes or with a few more hills, requiring some walking experience. The terrain is always easy and safe.
Ideal for: Those who walk regularly and want to challenge themselves a little.
Intermediate — this outing
Here we enter the world of true trekking. Steeper climbs, stretches on uneven or longer trails that require stamina. The physical effort is medium to high, and the fatigue is noticeable... but so is the satisfaction!
Ideal for: Those who already have experience and a good level of physical fitness.
Intermediate Plus
When the mountains begin to take their toll. More challenging routes in terms of gradient or duration, with technical sections or uneven terrain. Even a medium elevation gain can be tough if concentrated in just a few kilometers
Ideal for: Trained hikers, accustomed to walking on mountain paths
Difficult
Level suitable for experienced hikers with excellent stamina and surefootedness. The physical challenge is high, and there may be steep sections or possible exposure, which is always noted in the hike description. Perfect for those who enjoy pushing their limits and conquering significant peaks.
Ideal for: Those who already have experience in an Alpine environment and want to challenge themselves.
Difficult Plus
Only for true Guidders with their Wild Spirit at its peak Long routes, significant elevation gain (over 1,100 m), and technical or exposed terrain. Excellent physical preparation, sure-footedness, and the ability to manage fatigue at high altitude are required.
Ideal for: Highly trained and experienced hikers in the mountains.
Exposure and exposed sections
NONE
