IGN's Top 25 3237 OT is a hiking map with a scale of 1:25,000. It covers the southern part of the Hauts-Plateaux du Vercors Nature Reserve, part of the Diois and part of the Trièves. This is the map to have if you want to discover the Col du Rousset, the Glandasse, the Queyrie plain, the Jocou, the Col de la Croix-Haute and the area around Châtillon en Diois.
Like all maps in the Top 25 series, it features a wealth of precise details: roads, paths, vegetation types, waterways, caves, dwellings, etc. Tourist information is also included: lookouts, refuges, campsites, cross-country ski trails, tourist office, FFRP-marked routes (GR and GRP).
The contour lines have an equidistance of 10 meters, and show the relief through the projected shadow.
