Experience the solitude of a hidden valley, where beauty alone could not sustain the residents in decades past.

Your first hike takes you through the hills above Killybegs, with fantastic views back over Donegal Bay. Forest trails through a quiet valley lead you back to the coast. Narrow back roads take you past headlands, hidden beaches and inlets. Pass through Kilcar Village, where a visit to Studio Donegal (handwoven Irish tweed weavers) is well worthwhile.  Continue along the coast, passing Celtic ring forts – believed to be the “dwelling places of Fairies” to your overnight stop in Carrick.  After eating dinner in one of the village restaurants, there’s a good chance you’ll stumble upon one of the  legendary local traditional Irish music sessions in one of the village pubs.  Distance: 26 km.Altitude gain: Approx 500 metres.Terrain: Narrow paved roads, unpaved roads.

Descend from here to the beautiful Silver Strand beach at Malinbeg, before continuing to the historic valley of Glencolmcille where you spend the night. Glencolmcille is full of historic sites from all eras and well worth exploring.  Finish your evening off with a well deserved meal in a local restaurant and if you’re not too tired, you might catch a tune or two if you decide to stop off at one of the local pubs.
