Exactly as the title says, this is a beautiful high altitude route that’s a little technical in parts and definitely can only be done in the summer. They say Val Gerola is one of the sunniest spots in the valley – but it’s also one of the most snow-secure, so runs like this are only possible from late June onwards really.
Park in the very understated ski resort of Pescegallo, where the road ends. If you want to make an Alpine Bike of this, then you could do the 15 km climb up from Morbegno and leave your bike quite safely behind a tree (there are enough of them.)
There are rifugios on route if you need a sit down. About halfway around this route you’ll see the Rifugio Trona Soliva, that’s pretty popular as it has quite an easy route up to it (not the one you’re taking though). The food is great here.
Val Gerola is a treat for exploring, so don’t feel obliged to stick to this route.
