This climb runs from the northern edge of Bolzano, Italy, up into South Tyrol's Salto plateau, finishing above the hilltop village of Jenesien (San Genesio Atesino in Italian). It's 6.3 miles long, gains 3,852 feet, and averages 11.1% - one of the steepest ways in or out of Bolzano, and currently the 184th-hardest climb in our database. The road is a genuine relic - long before it carried cyclists it was a mule track, later surfaced with a distinctive grooved concrete-and-asphalt mix, still visible in places, meant to give vehicles grip on grades that pitch well into the 20s. The route weaves between those old lanes (Rafensteiner Weg, Jenesierweg, Dorfstrasse) and short stretches on the busier, tunnel-cut SP99 provincial road before a cobbled pitch into the village itself and a final push onto the open farmland of the Salto plateau. For decades the easy way up was the San Genesio cable car, out of service since November 2020. Bolzano and the province broke ground in 2026 on a roughly $40 million replacement, so for now the bike and this twisting old road are the only way up short of driving. The steepest, roughest stretch of the old road was itself rerouted onto a fresh run of switchbacks as recently as 2025, so don't be surprised if it looks different from older trip reports or photos.

The climb averages 11.1% over 6.3 miles, but that number hides how uneven it really is. The first mile out of Bolzano on Via Rafenstein is brutal, holding in the high teens with the steepest quarter-mile averaging 29.6% and the single steepest 100 yards spiking to 31.2%. A short section on the wider SP99 provincial road eases the effort into the low teens before the old lanes resume and pitch back up past 20% again on the approach to Jenesien. The final mile, once you're through the village and onto the open Salto plateau, settles into a more manageable 8-10%, a welcome change after everything below it. Gear for the steep pitches, not the average - a compact or sub-compact setup with a wide-range cassette makes the double-digit ramps survivable.

Roadway: The road is a real patchwork - the historic sections on Via Rafenstein and Jenesierweg still run on their original grooved concrete-and-asphalt surface, laid roughly a century ago over what was once a mule track, mixed with short, smoother stretches where the route merges onto the modern SP99 provincial road (including a brief tunnel around mile 1.75). The steepest, roughest section of the old road was itself rerouted onto a fresh run of hairpin switchbacks as recently as 2025, so expect it to look different from older photos or trip reports. Bolzano's comune completed a rockfall barrier and slope stabilization above Via Rafenstein in January 2026 after past rockfall risk in that stretch - check the province's road-status page for any temporary closures before you go, since this valley wall has closed the road briefly before.

Traffic: Traffic is light on the old lanes, which are narrow, residential, and lightly used by locals. The short stretch on SP99, especially through the tunnel around mile 1.75, carries more, faster traffic with reduced visibility, so treat that section with extra caution. Once the route leaves SP99 again near mile 5, traffic thins back out through farmland on the approach to Jenesien and the Salto plateau.

Parking: Bolzano's northern edge, where the climb starts at the Via Rafenstein/SS508 junction, is a residential neighborhood - street parking along the surrounding streets is the practical option, since we didn't find a dedicated climb-specific lot. The valley station for the San Genesio cable car, a short ride away, is currently a construction site as part of a 2026 rebuild of that system, so don't expect to park or stage there for now. Riders looking to combine this with other short, steep test-piece climbs nearby can use our Routes in the Area tool to see what else starts from Bolzano.

There are no services on the climb itself until you reach the village of Jenesien around mile 6, so top off water and food in Bolzano before you start. The grade is the real gear question here - sections average in the high teens and briefly touch the low 30s, so a compact or sub-compact crank paired with a wide-range cassette (34x34 or lower) is worth having rather than finding out you need it on the first mile. Jenesien itself has cafes and small shops if you need to refill before continuing on toward the Salto plateau or heading back down.

Bolzano is easy to reach by train and makes a good base for a few days of climbing before or after this one. South Tyrol's summers, roughly May through October, are the reliable window - the exposed upper switchbacks and the cobbled pitch through the village can be treacherous in wet or icy conditions outside that range. If you'd rather not descend on tired legs, note that the historic cable car linking Bolzano to Jenesien has been out of service since 2020 and won't reopen until its roughly $40 million replacement is finished; construction only broke ground in 2026, so plan on riding back down for at least the next couple of seasons. Once you're up on the Salto plateau, working farms and open pasture are a sharp contrast to the steep, walled-in lanes below, with the Dolomites visible on a clear day.
