Set of two double-sided maps to cover the whole of the Isle of Man. Roads, tracks & footpaths are shown, as are field boundaries. Hill country with public access is clearly marked, & the map also shows car parks & picnic sites. The TT course is shown in detail with its bends & other landmarks named. Contours are shown at 100ft intervals. The base cartography is reduced from 6 inches to the mile scale, which makes some of the lettering very small, but the names of the main features are reset at a larger size for clarity. The British National Grid is shown at 1km intervals (latitude & longitude are not shown).
