Donegal genuinely contains some of the best biking country in Ireland, IF you like to explore...
The Grianán is located on the western edge of a small group of hills that lie between the upper reaches of Lough Swilly and Lough Foyle. Although the hill is comparatively not that high, the summit dominates the neighbouring counties of Londonderry, Donegal and Tyrone. Located at the edge of the Inishowen peninsula.
Large forest park on the coast with lots of facilities for families. Accessible from the N56, heading West just after Dunfanaghy. Park in the Forest Park itself.
A fifteen minute ferry journey from Burtonport. A great day out with spectacular scenery, lung-busting climbs and exhilarating descents. All double-track and tiny tarmac roads. There are tracks and trails all over the island, so the possibilities are endless.
Start at Glenveagh or Gartan, or indeed anywhere along the way. Ordnance Survey Ireland Map 6. Some great climbs and fast rough descents. A 25-30 mile loop. Scenery fantastic.
The gruelling Glover Highlander route from Muckish to Errigal in Donegal, over 14 miles long and taking in eight peaks with 6,500 ft of ascent/descent.
Near Glenveagh National Park. Park at the car park on the south-eastern side (not marked on map), and get your bike up Donegal's highest mountain, at 750m.
Starting and finishing in Ardara, taking in Maghera, Port, Glencolmbkille, Teelin, climbing Slieve League, then back to Ardara via Glengesh. 80Km and over 2300m of vertical climbing.
