A legendary route that blends history, nature and pure adrenaline. The 100 Km dei Forti is one of the most iconic MTB trails in Trentino: an epic loop across Austro‑Hungarian fortresses, high‑altitude pastures, forest singletracks and fast descents overlooking the Adige Valley.
The itinerary unfolds through four distinct areas, each with its own technical features and unique atmosphere.
1) Valico della Valbona – Steady climbs and open views
The ride begins at Passo Sommo (1336 m), following the old military road that climbs gently along the Sommo ridge. The terrain is smooth and perfect for finding your rhythm as you reach Rifugio Stella d’Italia and Forte Sommo Alto (1579 m), the first historic highlight of the tour.
A short descent leads to Passo Coe (1614 m), gateway to the peaceful Campiluzzi Valley. The trail alternates between fast gravel sections and more technical stretches near the Campoluzzo mountain huts, before passing through a characteristic military tunnel (1275 m) and reaching Rifugio Rumor.
For riders: compact gravel, grassy sections, moderate difficulty, ideal warm‑up stage.
2) Towards Slaghenaufi – Ridges, forests and wartime history
From Rifugio Rumor the trail follows the ridge with rolling ups and downs and wide views over the Val della Lanze. It then reaches the Fiorentini provincial road and climbs to Malga Seconde Poste (1437 m).
A narrower, more playful trail leads to the former Grimmen and Clama huts, before crossing the Astico stream. A short but intense climb brings you to the hamlets of Tezzeli and San Bastiano, followed by the approach to Slaghenaufi (1245 m), an area rich in WWI heritage.
For riders: singletrack, mixed terrain, medium‑high difficulty, scenic and historic highlights.
3) Vezzena – Luserna – High‑altitude gravel and fortresses
After the military cemetery, the route follows the road to Spiazzo Alto and enters the dense forest of Seghetta (1225 m). A steady climb leads to the Forest Ranger’s House (1336 m) and the panoramic Passo Vezzena (1414 m).
A wide gravel road takes you to the Biseletto basin and the Bisele huts, before tackling the steep Val Morta, one of the toughest sections of the tour. The reward is the arrival at Forte Campo Luserna (1515 m), one of the most impressive Austro‑Hungarian fortresses.
A fast, flowing descent brings you to Malga Laghetto (1195 m).
For riders: wide gravel, steep climbs, fast descents, high difficulty, spectacular viewpoints.
4) Folgaria – Lavarone – Lakes, forts and forest flow
From the Lavarone Chapel, the route heads towards Gionghi and Bertoldi, then climbs along the forest road to Monterovere. A short paved section leads to the junction for Malga Laghetto, where the climb to Forte Gschwent – Belvedere (1180 m) begins.
The trail continues to Masi di Sotto and along the shores of the beautiful Lake Lavarone, before reaching Carbonare di Folgaria (1074 m).
For riders: smooth forest roads, panoramic stretches, medium difficulty, excellent flow.
5) Folgaria Plateau – The grand finale
From Carbonare, the trail climbs towards Malga Clama and Malga Seconde Poste, then steepens towards Malga Prima Posta (1425 m) and Forte Cherle (1444 m).
The route continues to Forte Sommo Alto and then along the mule track to Forte Dosso delle Somme (1667 m), the highest point of the entire 100 Km dei Forti.
A long descent crosses Roccolo, Serrada and the woods leading to Francolini, with a fun and flowing singletrack. The final stretch heads towards Folgaria and then to Passo Sommo, closing the loop.
A last descent brings you back to Carbonare, passing through small alpine hamlets.
