Dunluce Castle Ruins

Highlight • Natural Monument

Dunluce Castle is a now-ruined medieval castle in Northern Ireland, the seat of Clan McDonnell. It is located on the edge of a basalt outcropping in County Antrim (between Portballintrae and Portrush), and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.

Cave Hill Cave

Highlight • Viewpoint

These beautiful ancient cave formations in Cave Hill Country Park lay inside the largest and highest granite outcrops in the region. The caves are home to indigenous cave paintings that tell the Dreamtime creation story of the Seven Sisters. The route bypasses the cave however, if you have time, it's definitely worth stepping inside and exploring.

Cushendun Caves

Highlight • Natural Monument

The caves near Cushendun Beach formed over hundreds of millions of years and became famous after appearing in the hit series Game of Thrones.
And the fact that they are a stone's throw from the pretty little village of Cushendun makes them a great stopover

Cladagh Glen Waterfall

Highlight • Forest

Clodagh Glen has a steep sided gorge that is lined by ancient ash trees that cling to the steep sides. The water sculpted river valley has a spectacular arch over the river which formed when the cave roof collapsed. The reserve is known for its limestone gorge, mystical caves and beautiful waterfalls.

In the springtime the valley floor is carpeted by bluebells, wood anemones and wild garlic and in the summer silver-washed fritillaries are found besides the path. With a keen eye you may also spot an elusive pint martin and red squirrels!

Pollnagollum Cave (meaning Hole of the Dove) is the longest cave system in Ireland. The cave system is complex and fascinating and is fed by a tumbling waterfall that topples off a limestone cliff. Watch your stepping here as rocks can be unstable and slippery, and don't forget your camera for some awesome shots.

De Burgh's castle was primarily a military fortress, notable for its robust defensive features typical of Norman architecture. The design included impressive walls and strategic positioning to take advantage of the natural defensive advantages of the clifftop location.

After a rocky and dreary section, the "view into paradise" comes through this bottleneck, almost out of nowhere. This walking section is unique!

A very impressive castle, part of which has collapsed into the sea along with the cliff. The visit can easily be combined with a visit to the Giant's Causeway.

"continual slur on Irish caving" It's actually only a few hundred metres is accessible and it's total length is thought to be 2km. No where near the longest cave in Ireland. Consider a trip in only if well equipped with a good light and helmet. Alternatively/also consider visiting McKenzies back lounge just down the road. A much drier watering hole. ;)

The beach is surrounded by dunes that are covered with wildflowers in summer, and it is an area of scientific interest with many fossils. It is a paradise for wildlife and one can spot rare butterflies, orchids, birds.
