The Causeway Coast’s natural site of polygonal basalt columns attracts millions of visitors to the Northern Irish coast. The popular Causeway Coastal Walk is a two-mile walk from the Windy Gap to the Giant’s Causeway. The longer alternative is a 33-mile route from Portrush to Carrick-a-Rede to Ballycastle; visitors often drive along the coast and take a circular hiking route on one part of the trail. If braving the full two-day trek of the coast, often called the Ulster Way, be sure to stop at Dunluce Castle and the natural rock arches.

Tollymore Forest Park Walk, located in County Down, is a five-mile walk running along the Shimna River through beech and coniferous forests. With beautiful surrounding views of the Mournes and woodland terrain, this is the perfect hiking trail for the avid camper. Luke’s Mountain peak can be seen from the latter half of the trail, along with various wildlife and the Boundary Bridge crossing below. With surrounding facilities for campers and families and nearby accommodation, this is a great trail for novice hikers.

The Ring of Gullion, another Area of Outstanding Natural Beauty, includes the Slieve Gullion, the ring dyke most famous for its volcanic origin and conservation. At almost 10 miles, this circular route is a challenging uphill walk to the Neolithic South Cairn Passage Grave at the top (which can be extended higher, depending on the hiking route). Along the trail, hikers can look out for Slievenacapple and the carvings of Finn MacCool, the legendary Irish giant who is believed to have built the Giant’s Causeway as a wall of protection from Scottish enemies.

Rostrevor is a small town at the south end of the Mournes, beside Warrenpoint, with a number of great walks and hiking routes, ranging from 0.5 to 5 miles in distance. The longest of the three starts at the base of Kilbroney Forest Park, running upward to the base of Cloughmore Stone. From here, hikers can make the short forest walk up to the stone, where many visitors carve their name into the rock. The surrounding views overlook the stunning Carlingford Lough, the passage of water running between Northern Ireland and the Republic of Ireland.

Rathlin Island is a short boat trip from the Causeway Coast, and has a small population of around 150 people. The entire island covers four miles and sits in between the Northern Irish and Scottish coasts. The route includes beautiful views of both coasts, along with a lighthouse and Church Brae, which sits on Slieveard. A surprising feature of Rathlin Island is the vast population of puffins, which attracts many visitors from the main coast.

The Divis Ridge Trail is an approximately four-mile walk from the Long Barn to the Black Mountain and the Mournes. The route overlooks Belfast, with a 180-degree view of the city on one side, and of the Mournes on the southern side. Spot birds of prey, like peregrine falcons, along the way. Most of the year, this landscape is a blanket of purple heather and makes for a great summer walk with a view of Belfast docks and central city.
