TOP 25 maps (maps where the code ends in "T") are for places of 'intéresse aux touristes'. They are real walkers' maps with a wide variety of useful information on paths and tracks such as, long distance GR (Grande Randonnée) routes, interesting unsignposted ways along footpaths, cross-country or high mountain skiing routes, hard parts of a hiking trail, restricted zones, huts and mountain refuges. Terrain information is clearly depicted such as lakes, swamps, marsh, tree-lined streams, cascades, damns, navigable canals, different sorts of woodland, brush and unusual features such as mines and caves. Other useful information for the visitor includes campsites, riding centres, climbing and hang-gliding sites, recreation areas, golf and tennis facilities, canoe and kayaking locations. Also shown are National Park boundaries, cities and towns of particular interest, notable monuments and maybe most importantly TIC (tourist information centres). The map legend is in French and English and each TOP 25 map covers an area of approximately 28 x 21 km (17 x 13 miles) with contour intervals at 5 metres, except in mountainous areas where the maps have hill shading and contours are every 10 metres. This map comes supplied with a handy distance measuring ruler, specifically printed for use with 1:25 000 scale mapping, which when placed onto the map allows the user to instantly read off point to point distances (as the crow flies) in either miles or kilometres. The reverse shows the more important items from the Top25 map legend.
