Monte Renoso-Bastelica 4252 OT GR20

Topographic survey of France at 1:25,000 in IGN’s excellent TOP25 / Série Bleue series. All the maps are GPS compatible, with a 1km UTM grid plus latitude and longitude lines at 5’ intervals. Contours are at 5m intervals except for mountainous areas where the maps have contours at 10m intervals, vividly enhanced by hill shading and graphics for rocky terrain. Colouring with graphics indicates different types of vegetation or land use (deciduous or coniferous forests, moors, orchards, vineyards, etc).

PLEASE NOTE: coverage of France at this scale is currently being revised – the format and the presentation of each title are indicated by the letters at the end of its Sheet Reference number (e.g. 0416ET, 3531ETR, 1923SB, etc.)

MAPS WITH FULL TOURIST OVERPRINT & AN ENGLISH MAP LEGEND: all TOP25 maps and the SB editions of Série Bleue have an overprint highlighting waymarked walking trails including long-distance GR routes and, where appropriate, ski routes. Symbols indicate campsites, gîtes d’etape, refuges, equestrian centres and other recreational facilities or sites, tourist information centres, cultural heritage, etc. Towns and locations of particular interest are highlighted.
