This 1:25000 map, on water resistant paper, shows Lough Erne and its surrounding hinterland on an 840mm x 1230mm (approx) sheet with the Upper Lough on one side and the Lower Lough on the other. The map shows full details of the lakes and all the navigation marks and features including jetties and landing places. It also has spot depths and submarine contours along with the normal full detail you would expect on an OS map on land. The map folds down to approx 140mm x 210mm and is presented in a protective plastic sleeve.
