Discovery maps are the Irish equivalent of the OS Landranger series; designed for walkers, ramblers, off-road cyclists and horse riders, but also containing extensive information for the casual tourist. There are no Explorer equivalent maps (1:25 000 scale) for Ireland, but the Discovery mapping is very detailed, allowing it to be as useful for walking as possible. Relief is shown by layered tints with contours at 10 metre vertical intervals (this really makes the map rather attractive). The map shows footpaths, tracks and waymarked walks as well as cycle routes including the National Cycle Network.
This map comes supplied with a handy distance measuring ruler; specifically printed for use with 1:50 000 scale mapping; when placed onto the map it allows the user to instantly read off point to point distances (as the crow flies) in either miles or kilometers.
The map provides comprehensive information on land features including canals, footbridges, tidal limits, marsh, cliffs, various types of woodland, National Trust land, as well as more general detail such as churches, post office and public houses. Information for tourists includes camp and caravan sites, gardens, golf courses, information and visitor centres, yacht clubs, picnic sites, public conveniences, telephones, viewpoints, bus stations and youth hostels. The tourist and leisure information is also written in French and German.
There are altogether 93 maps in the Discovery / Discoverer series in total; which cover the entirety of Ireland; 75 "Discovery" maps are published by Ordnance Survey Ireland to cover Southern Ireland, and running alongside these 18 "Discoverer" maps are produced by Ordnance Survey of Northern Ireland to cover areas in Northern Ireland.
