For me as an e-biker, this is the better alternative to get to Passo Tremalzo. Also because I prefer descent 779a to this one. I agree 100% with everything that has been written here about the gradient and the surface. Watch out for oncoming traffic. From Passo Nota onwards, it gets really tough.

Segment that connects Ledro to the Nota pass, most of it concreted with gradients over 20% and stretches of dirt road with loose gravel, very demanding for muscular muscles, preferably e-bikes, almost all in the shade of the forest, be very careful on rainy days which make the surface slippery.

Only recommended for strong bikers and mountain specialists! All the information here from eBikers gives a distorted picture. The climb from Molina to Bocca dei Fortini is quite steep. Most of the time there are gradients of 20%. On average a solid 15%. In addition, it is partly over loose gravel, so you also need the right riding technique to tame the constantly rising front wheel. In many places the route is now asphalted. The path leads almost entirely through the shade. There are no food options along the way. Beginners and eBikers should avoid the route unless they are willing to put themselves through (a lot of) effort. The view makes up for it.

Very steep ramp, there is a small plateau in between where you can take a break, I would recommend it for e+bikes

Very difficult to drive. At least S2. A lot of rubble, loose stones. You have to push every now and then! Nevertheless, a very nice downhill trail!

Climb that connects Lake Ledro with Bocca dei Fortini. The climb is not to be underestimated, it is almost entirely cemented due to its slope, which becomes arduous especially towards the end. Once you reach the top you can opt to go right towards Tremalzo, or left towards Pregasina and Riva del Garda, stopping at Punta Larici.

For experienced cyclists seeking a significant challenge, the region offers several demanding passes. Hofmahdjoch / Passo Castrin is a first-category climb known for its length (22.2 km) and average gradient (5.7%), often featured in major cycling events. The Ballino Pass, part of a challenging 50 km loop with 1,050m of elevation gain, also provides a rewarding experience. Additionally, the Bocca dei Fortini Pass Road features sections with gradients exceeding 20%, making it a formidable climb for both enduro and gravel biking.
Many passes around Arco boast stunning vistas. Passo Duron provides a wide view over the Lomaso basin and the surrounding mountains.

You can find many more routes in the Gravel biking around Arco guide.
The region around Arco is rich in unique natural features. The journey to Ballino Pass often includes picturesque views of Lake Tenno, known for its turquoise waters. Routes through the Marocche di Dro offer a distinctive 'stone and rock desert' landscape, a protected post-glacial landslide area. Additionally, the 'Marmitte dei Giganti' (Giant's pots) near Nago, evidence of glacial erosion, are a fascinating natural attraction along some routes.
Beyond cycling, the region offers a variety of outdoor activities.

The Bocca di Trat Scenic Road, leading towards Rifugio Pernici, is a gorgeous climb that becomes less frequented by auto/Kradverkehr in its upper third, offering a peaceful ascent through beautiful scenery. Its partly gravel sections also deter some traffic, providing a more secluded feel.
