The Carbon Trail begins at Alpe di Neggia and follows one of the most varied descents in the Gambarogno region.
Originally a hiking trail, it was later upgraded by local authorities for mountain bike use and was included in the official “SwitzerlandMobility” MTB network for several years.
Due to increasing trail conflicts and irresponsible behaviour, the route was eventually removed from the official network. Despite this, the trail itself remains unchanged and continues to offer one of the finest descents in the area.
The climb to Alpe di Neggia
The ride starts from the parking area in Magadino (199 m), where free parking is available.
From here, follow the main road through Vira Gambarogno before tackling the long paved climb to Alpe di Neggia (1394 m).
Given the length of the climb, it is advisable to carry enough water, as some fountains may be turned off during dry summer periods.
During the summer season, an alternative is to use the bus service between Magadino and Indemini, which can carry up to five bicycles. In this case, get off at the “Alpe di Neggia, Alpe” stop.
The Carbon Trail
The descent starts with a series of switchbacks over loose, rocky terrain (S2). As the trail approaches Valle Vadina (1056), the surface becomes rougher and slightly more technical (S2+).
At the valley floor, cross the stream before a short climb consisting of a stone staircase, where a short hike-a-bike section is unavoidable, followed by a rideable uphill trail with a few technical sections.
The climb ends at Alpe di Trecciura (1157 m), where a fountain is available. A short descent leads into Valle di Trecciura (1132 m). After crossing the stream and pushing the bike for a few metres, the trail enters a beautiful beech forest, where it follows a fast and enjoyable traverse (S2).
At the next stream crossing (1052 m), the trail becomes narrower and slightly more exposed while remaining technically moderate (S2). It then continues towards Monti di Vira di Sopra (959 m) before descending through the Monti di Vira to around 760 m, where the route re-enters the forest.
At the junction at 741 m, you can either continue along the classic Carbon Trail towards Vira Gambarogno, a smoother option characterised by loose rocky terrain, or follow the alternative described here towards Quartino.
From this point, the trail narrows considerably and features several tight switchbacks that may require nose-pivot turns (S3).
At the forest road (576 m), turn left to reconnect with the paved road towards Orgnana.
If you want a more technical finish, you can instead continue right towards Monte Bruno (566). A gently undulating traverse follows the mountainside to Al Sasso (544 m), with a few exposed sections but generally moderate difficulty (S2).
Beyond this point, the character of the trail changes significantly. Rock steps, sustained steep gradients and demanding technical features raise the difficulty to S4, requiring confident bike handling. The final section gradually becomes smoother before reaching Via Loco (230 m).
From here, descend to Quartino and follow a short stretch of asphalt to the cycle path, which leads back to the starting point.
Trail notes
The official trails should always be followed, particularly through the Monti di Vira. Even where the trail is eroded, avoid creating or using alternative lines.
Several gates are crossed along the route and should always be closed after passing through. Livestock is common throughout the area, particularly cows with calves, so extra care and respectful behaviour are essential.
The Carbon Trail is a shared-use hiking trail. Hikers always have priority: slow down when approaching, give way where necessary and pass only when it is safe to do so.
In villages and around the “monti”, ride at a moderate speed and respect residents, walkers and other trail users.
During autumn, fallen leaves and damp conditions can make the lower technical section particularly slippery. In these conditions, it is generally preferable to finish the descent towards Magadino or Vira Gambarogno rather than continuing to Quartino.
