Appearing from an underground cave, the Cladagh River flows down a narrow, steeply-sided gorge.

These are a set of three sites which collectively comprise the Marlbank Nature Reserves. They include the Marble Arch Forest Nature Reserve, the Killykeeghan and Crossmurrin Nature Reserve and the Hanging Rock and Rossaa Nature Reserve. Over a relatively small area, visitors can discover caves, steep gorges, cliffs and woodlands, as well as areas of extended grassland covered in wildflowers. Sturdy footwear is recommended.

Marble Arch

Appearing from an underground cave, the Cladagh River flows down a narrow, steeply-sided gorge towards the Erne lowlands. Marble Arch Nature Reserve takes its name from the polished limestone arch over the river which people used to think was marble. The arch was formed when a cave roof collapsed. Take a walk beside the river as it tumbles over waterfalls and cascades along the gorge.

The Visitor’s Centre at the Marble Arch Caves Global Geopark is open from late March to September and has toilets and a café.

Killykeegan and Crossmurin

Set between the stunning Cuilcagh Mountain and the Erne lowlands is Northern Ireland’s only area of limestone grassland. A few patches of hazel scrub remain dotted through the grassland because the area has been cleared for farming since the Stone Age. The scrub shelters delicate woodland flowers including wood sorrel and primroses.

There are toilets, a car park and information panels at Killykeegan cottage.

Hanging Rock and Rossaa

Overlooking Lower Lough MacNean is the Hanging Rock, a magnificent 50 metre high limestone cliff. Yew and juniper cling to its cliff face. At the foot of the cliff is one of the finest ash woodlands in the country. In Rossaa Wood to the west, savour the sight of mature oak, beech, willow and elm and seek out the colourful yellow blooms of the Welsh poppy growing on the grassy slopes. There is limited parking in a small lay-by on the side of the road. There is a short path to where a river emerges from underground.
