Donegal genuinely contains some of the best biking country in Ireland, IF you like to explore...
On the coast with lots of facilities for families, Ards is one of Ireland's finest forest parks. Lots of options and great scenery, and plenty to see and do. Well worth a visit if in the area. Be especially mindful of other forest users, as this is a popular attraction.
A fifteen minute ferry journey from Burtonport. A great day out with spectacular scenery, lung-busting climbs and exhilarating descents. All rough double-track and tiny tarmac roads. There are tracks and trails all over the island, so the possibilities are endless.
Some great climbs and fast rough descents, with a mix of tarmac and rough tracks. The scenery is fantastic on this 25-30 mile loop.
Get your bike up Donegal's highest mountain, at 750m, if you fancy a long carry, and a VERY technical and tricky steep loose-rock descent.
Starting and finishing in Ardara, taking in Maghera, Port, Glencolmbkille, Teelin, climbing Slieve League, then back to Ardara via Glengesh. This is an all-day epic, only to be undertaken if you are used to long days in the saddle, and you don't mind hills! There are lots of opportunities to cut it shorter though if required (or indeed, make it longer!). 80Km and over 2300m of vertical climbing.
