Discovery Sheet No. 03 covers part of Counties Derry and Donegal.
This map is situated mostly in County Donegal and features a small part of County Derry.
Malin Head is located to the North of Sheet 3 and is also the most Northerly point on the island of Ireland. The Headland is surrounded by Lough Swilly to the West, Lough Foyle to the east and the Atlantic Ocean to the North.
A number of beaches can be found on Sheet 3 such as Back Strand, White Strand Bay and even Magiligan Strand in County Derry. Inishtrahull Island also features on Sheet 3. It is the most Northerly Island of Ireland.
There is a designated waymarked walk that loops at Inishowen Head. It passes over a portion of Crocknasmug mountain. Lough Swilly is a glacial fjord, one of only three in Ireland. The Lough is famous for its wildlife-watching and the numerous shipwrecks found there. Lough Foyle is the estuary of the River Foyle.
Discovery maps are produced at a scale of 1:50,000 (or 2cm on paper equals 1 kilometre on the ground). Each Discovery Sheet covers an area of 40km x 30km surface area (with the exception of several portrait-format sheets, which are 42km x 32km). This is a comprehensive series of feature-rich maps which show detailed landscape information, like rivers, lakes, contours and many townland names. The Discovery Series is designed primarily for tourist and leisure activities; these maps are the preferred choice for hill walkers and those in pursuit of the great outdoors. It is also an ideal reference for location-focussed business use, in pocket-friendly folded form or as a wall-mounted reference.
