High above Cookstown, at the foot of the impressive Sperrin Mountains, you will find the Beaghmore Stone Circles. This is one of Ireland's most fascinating archaeological sites. Only rediscovered in the 1940s during peat cutting, the bog revealed a complex of seven stone circles, ten stone rows, and numerous Bronze Age burial mounds. For a cyclist, the road to Beaghmore is an experience in itself. The route takes you away from the inhabited world into a vast, quiet landscape where the wind has free rein. The complex itself exudes an enormous sense of peace and is the perfect place to get off your bike and soak up the prehistoric atmosphere.
