French Hill Climbs — road gradients measured by LiDAR
Road climbs across the Alps, the Vosges, the Pyrenees, the Massif Central, the Jura, Corsica, Provence, the north-west, the north-east and the Centre (70 departments), measured on IGN’s LiDAR HD 0.5 m laser surveys and ranked by the steepest 25 m — part of the HowSteep survey. What the survey is, and how to read a gradient ladder →
Surveyed here: the great cols and the village ramps alongside the steep lanes only the locals knew, found by the same systematic search that produced the UK catalogue.
France so far is the Alps, the Vosges, the Pyrenees, the Massif Central, the Jura, Corsica, Provence, the north-west, the north-east and the Centre — the departments between the Rhône and the Italian border, from Lake Geneva to the Mediterranean; the Vosges massif from the Ballon d’Alsace to the Donon; the six Pyrenean departments from the Atlantic at Hendaye to the Mediterranean at Banyuls; the volcanic uplands and gorges of central France; the limestone plateau and passes along the Swiss border; the island’s high cols and coast roads; the hills and coast east of the Rhône; the Suisse normande, the Perche and the Alpes mancelles, from the Channel to the Loire; the Ardennes, the Argonne and the côtes de Meuse, the Montagne de Reims and the Boulonnais; and the Loire valley from Tours to Sancerre, the Berry and the western edge of Paris. The rest of the country follows region by region as IGN’s LiDAR HD survey completes its national coverage; Brittany, the Bassin Parisien, the Morvan and the Nord wait for IGN to publish their ground model. One well-known Vosges climb, the Col du Petit Ballon, is not here yet: the roads at the pass carry no name or number in OpenStreetMap, so no route could be built for it.
Every climb here carries a surface and access chip from BD TOPO®, IGN’s national topographic database, cross-checked with OSM; a road the database marks as restricted (seasonal closure, forest road, permit, toll) ranks with that restriction stated. Where a check is still pending, the page says so.

Surface: · Caveated rows: (ranks stay the true ranks) · paved is preselected and the toggle drives every ranking table below; gravel, mixed and surface-unverified roads appear under all surfaces. Ranked by one steepest window, a row may be a brief sharp pitch or a sustained traditional climb — the Length and Overall columns tell you which.

Net rise is the endpoint elevation difference; total ascent counts every metre climbed, including dips regained — and, since it adds the small rises of an unsmoothed 1 m profile without ever subtracting, read it as indicative rather than surveyed (why).

Road status under review
Measured like everything else, but these roads are absent from (or barely touched by) the BD TOPO® road network — usually a forest or farm track, a private drive, or a map phantom. The class sits out of the rankings until verified — each one returns as evidence clears it. Pages stay live and honest.
