Situated at the confluence of the Rivers Camowen and Drumragh, which join to form the River Strule, Omagh is a busy market town with a handful of historic Georgian buildings. Pick up a Town Trail leaflet from the tourist office. Sadly, for a long time to come, Omagh (An Óghmagh) will be remembered for the devastating 1998 car bomb that killed 29 people and injured 200.
Dungannon is a pleasant enough market town halfway between Cookstown and Armagh, worth a brief stop in passing if you want to do a spot of shopping. Killymaddy Tourist Information Centre (8776 7259; www.flavouroftyrone.com; 190 Ballygawley Rd; 9am-5pm Mon-Fri, 10am-4pm Sat & Sun) is at a caravan site 10km west of Dungannon on the A4 road towards Enniskillen.
Cookstown boasts the longest (2km) and widest (40m) street in Ireland, the legacy of an over-ambitious 18th-century town planner, but apart from that there’s not much to see in town. The main sights here are in the surrounding countryside. The tourist information centre (8676 9949; www.cookstown.gov.
The village of Gortin, about 15km north of Omagh, lies at the foot of Mullaghcarn (542m), the southernmost of the Sperrin summits (unfortunately capped by two prominent radio masts). Hundreds of hikers converge for a mass ascent of the hill on Cairn Sunday (the last Sunday in July), a revival of an ancient pilgrimage.
About halfway along the A505 between Omagh and Cookstown (20km east of Omagh) is An Creagán Visitor Centre, with an exhibition covering the ecology of the surrounding bogs and the archaeology of the region. Informative nature trails start near the visitors centre. There are 44 prehistoric monuments within 8km of the centre, including the Beaghmore Stone Circles.
