For walkers who prefer the greater detail on 1:25,000 scale maps (1cm = 250m or roughly 2½in = 1 mile), the IGN publishes no less than six sheets to cover the same area. Headed TOP 25, these are: 3535 OT Névache; 3536 OT Briançon; 3435 ET Valloire; 3436 ET Meije-Pelvoux; 3335 ET Le Bourg d'Oisans-L'Alpe d'Huez; and 3336 ET Les 2 Alpes.

Note: IGN TOP 25 maps are being allocated a UTM-WGS 84 grid to enable the position given by a GPS receiver to be easily localised on the map.

Using the Guide

This guide follows a clockwise circuit round the Parc National des Écrins from valley to valley. Each major valley system is treated within one section (or chapter) in which a number of walks of various grades are described. The only exception is Valjouffrey, which is described in the Valgaudemar chapter. All the walks are listed in the index at the end of the book. As mentioned above, the grading system ranges from 1 to 3, with the lowest number referring to the easiest and/or shortest walks, Grade 2 for moderate and medium length outings, and Grade 3 the longer and more demanding routes. However, this simplistic system will inevitably have variations and (no doubt) a few anomalies which may be disputed by users of this book, but they are offered in good faith and as a rough guide only.
