Embark on the challenging "From Lake Ledro to Monte Tremalzo — ring tour," a mountain biking adventure spanning 27.1 miles (43.6 km) with a significant 4650 feet (1417 metres) of elevation gain. This difficult route, typically completed in around 4 hours and 14 minutes, offers breathtaking panoramic views of the glacial Lake Ledro, the crystal-clear waters of Lake Garda, and the majestic Brenta Dolomites. You will ride through diverse terrain, from well-preserved dirt military roads and gravel forest paths to cobbled mountain roads and some paved sections, all while surrounded by extensive forests and alpine meadows.
This ring tour demands very good fitness and advanced riding skills, as some sections are technically challenging and may require you to push your bike. The climb to Tremalzo, while long, is manageable for experienced riders, but be prepared for challenging hairpin bends. The descent features very steep sections with extremely coarse gravel and rocks, so ensure your brakes are in excellent condition and you are adaptable to varied surfaces. You can find opportunities for breaks and refreshments at points like Rifugio Alpini Passo Nota along the way.
This route is considered a legendary and cult destination for mountain bikers across Europe, partly due to its unique historical dimension. A significant portion of the trail follows old military roads originally built by the Italian army during World War I. Furthermore, the region is part of the "Alpi Ledrensi e Judicaria" UNESCO biosphere, highlighting its rich natural beauty and biodiversity. The combination of demanding climbs, technical descents, and ever-changing landscapes provides a truly thrilling and rewarding experience.

A classic ascent in enduro but also feasible in Gravel.
Great fun downhill with Gravel bikes.
At times the slope exceeds 20%!
Beautiful dirt / concrete road that leads from Lake Ledro to the Bocca dei Fortini pass, on the military road that runs through the mountains above Limone/Vesio.

This MTB tour is a must for all MTB fans here on Lake Ledro. The ascent as a biobiker is more humane via Pieve, as gravel roads only begin at the end, the last km. The descent then has a lot of gravel road and very loose gravel on the other side of the pass. You're better off with an MTB with wider tires than my Elite_Race with "only 2.20" 👍🏽😄 Highly recommend this tour, just like the “Ponale” up to Lake Ledro
Clockwise for the uphill mountain bikers. Other direction for downhillers👍😂
This really is one of the most beautiful mountain bike tours the landscape has to offer. 🚵🏻😀
Oh my God 💕 There are days when everything just fits After the many beautiful impressions of the last few days 🏡 I thought there was no more to it and then the Tremalzo Pass came along 🛣 We started from Lake Ledro 🏖 over the northern flank ... over 20 bends up the pass road to the summit tunnel 🚇 at 1665m ... and that wasn't enough of the highlights ✨️✨️ we went down the southern flank ⛰️An old military road with a gradient of 14% in places 🚧 a gravel track at its finest 💕 In the end we agreed that this was one of the most beautiful tours we have done 🫶🏻... the long journey was more than worth it 😍 Little tip ⚠️ I wouldn't have wanted to drive the pass the other way around 😬
Nice ride in excellent company between Lake Ledro and Tremalzo, fantastic views, thanks to everyone, good 💪💪💪 it was a pleasure to meet you 🤙🌈, see you next time.
The descent on the south side offers incredibly spectacular views of Lake Garda. The tour is certainly one of the most beautiful bike tours in the region! But be careful: the descent is only suitable to a very limited extent for road bikes. Extremely coarse gravel and rocky in places. In addition, the entire descent to Lake Ledro is very steep and requires good brakes!
Unfortunately, my phone battery died 😥 It was a really nice tour!! 🥰
Hard core, despite the e-bike. The battery was empty after the summit tunnel
