In Tyrone, the largest county in Northern Ireland, you'll find fascinating prehistoric sites, lovely forest parks with herds of deer, and of course the beautiful Sperrin Mountains, which stretch for nearly 65 kilometers. With blanket bogs and heather on the upper reaches and farmland and wooded valleys in the foothills, the Sperrins offer excellent attractions for hill walkers and cyclists. Visitors can fish for trout in the tributaries of the River Foyle, or see the many standing stones and burial cairns in the area. Near Cookstown, you'll find the 10th Century Ardboe Cross, the Iron Age fort at Tullyhogue, and the Beaghmore Stone
