Shape: stepped — 49% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 113 m.
Found purely from mapping and LiDAR data, and not yet matched against books, race records or lists — it may be well known to locals under a name we've never heard. It was cross-checked against the GIP.at road network, OpenStreetMap and a second terrain model, but a discovery can still be an artifact of the terrain model or the map. Treat it as a well-evidenced hypothesis until someone has ridden it. If you know this road, tell us what you found — photographs, corrections and local knowledge all welcome; the map links below let you scout it first.
≈ Overhead cover (tree canopy or structures) spans 34% of this route — detected by comparing the surface model (DSM, treetops and rooftops) against the terrain model (DTM, bare ground). Under cover the bare-ground model is built from fewer laser returns, so metre-scale readings can wobble; maxima whose window sits in a covered zone are marked ≈ below — less certain — the flag does not say whether the true value is higher or lower. Longer windows average over more clean ground and are steadier.
Gradient ladder what do windows mean?
| Window | Maximum | Located at | |
|---|---|---|---|
| 2 m (diagnostic) | ≈26% | 165–167 m | under overhead cover terrain reads 36.8% at 181–183 m across a structure — excluded |
| 3 m (diagnostic) | ≈24% | 164–167 m | under overhead cover terrain reads 34.3% at 180–183 m across a structure — excluded |
| 5 m | ≈21% | 142–147 m | under overhead cover terrain reads 31.1% at 179–184 m across a structure — excluded |
| 10 m | ≈21% | 142–152 m | under overhead cover terrain reads 28.8% at 64–74 m across a structure and terrain that holds no road surface (dense canopy, no bench) — excluded |
| 20 m | ≈20.0% | 133–153 m | under overhead cover terrain reads 26.0% at 62–82 m across a structure and terrain that holds no road surface (dense canopy, no bench) — excluded |
| 25 m | ≈18.5% | 128–153 m | under overhead cover terrain reads 24.7% at 55–80 m across a structure and terrain that holds no road surface (dense canopy, no bench) — excluded |
| 50 m | ≈11.7% | 201–251 m | under overhead cover terrain reads 20.7% at 45–95 m across a structure and terrain that holds no road surface (dense canopy, no bench) — excluded |
| 100 m | ≈10.5% | 201–301 m | under overhead cover terrain reads 17.3% at 128–228 m across a structure — excluded |

This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.
Surface: paved (5% unpaved), according to GIP.at, Austria's official transport graph: surface unrecorded for the first 10 m; paved for the first 775 m; surface unrecorded from 775 m to 1,285 m; unpaved from 1,285 m to 1,325 m; surface unrecorded from 1,325 m to 1,405 m; paved from 1,405 m to 1,475 m; unpaved from 1,475 m to 1,525 m; paved from 1,525 m to 2,245 m; surface unrecorded from 2,245 m to 2,645 m; paved from 2,645 m to 2,705 m; surface unrecorded from 2,705 m to the top. The steepest 25 m lies on the paved part.
Access: Listed 2026-09-11 (texture re-measure): with the step masked the steepest 25 m reads 18.5 %, below the ranking door — kept as a listed page.
Measured, not vetted. This page records what the laser record shows about the road's shape — nothing more. Nobody has necessarily ridden or inspected this road for the survey, and a page here is not a recommendation and no guarantee that the road is open, surfaced, rideable or safe. Gates, private sections, missing rights of way and hazards do not show up in elevation data. Check access and conditions on the ground and make your own judgment.

Profile
The map, profile and gradient chart share one position — move your pointer over them and the marker follows. Colors are the gradient bands; the shaded span is the steepest 25 m. Any 25 m figure is good to about a point either way (why).
