Maps - Paper maps / Electronic Maps
An online map I have created to show the overnight stops as decribed in the Cicerone Guide to 'Trekking the Pyrenean Haute Route'. View the map here.
It uses Open Street Maps but with the 'Outdoors' layer superimposed that actually marks the Haute Route and its varients on the map - Usage limit exceeded :(
The Carte de Randonnees 1:50,000 Hiking Maps. Available from stanfords.co.uk. Can also be purchased from Amazon and Ebay. I did however find that although the maps are ajoining; on one section, some clever cartographer decided to put the cover & key on the section of the maps where the trail passes, so I was in fact missing a section. This section I completed with a screen shot of the online Open Street Maps.
Open Street Maps (OSM) are a free online map. Best viewed using the 'Cycle Map' Map Layer - one the right had side of the maps. See the map here.
A great app for both Android and iOS is Maps.me. It is based on OpenStreetMaps.org (above) and is downloadable and usable offline. I found it invaluable at times when my 1:50,000 map just didn't have the detail needed and the trail was poorly defined on the ground. Highly recommended for both mountain and city use! Remember: Don't rely on electronic mapping for navigation in the mountains; use it as a suppliment to paper maps and route finding skills.
