Venabygdsfjellet from Hamna

15544.7 m · net rise 362.1 m · total ascent 469.5 m · overall 2.3% · evidence quality B (good) · Stor-Elvdal · Innlandet

Shape: stepped — 56% of the climbing sits in a quarter of the distance; longest continuous stretch at 10%+ is 307 m.

Not yet matched against documented climbs — the measurement stands on its own.

This climb's data: OCL JSON — the full gradient ladder, quality flags and provenance in the OpenClimb Ladder format.

Surface: paved throughout, according to NVDB, Norway's National Road Database.

Access: Ranked 2026-10-05 (D27, road authority): NVDB carries 100% of the route as public road (0% restricted), which answers the OSM audit question (barrier gate without an access tag). A barrier gate without an access tag sits on the route; gates on public roads are usually seasonal — check on the ground.

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.

Route colour = gradient over a 25 m window: <10% 10–20% 20–25% ≥25%

Route line = the road surface as the LiDAR survey finds it. Basemap roads are for orientation and may sit a few metres off.

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).
