Route:From Cladagh Bridge on the Florencecourt to Belcoo Road walk up the Cladagh Glen alongside the river which journeys along a narrow, steeply-sided gorge towards the Erne Lowland. The gorge is thickly covered by a long established ash woodland.
The Arch over the river, formed when the cave roof collapsed, gets its name from the polished limestone which people used to think was marble. Wood goldilocks grow here as evidence that this is a very old woodland, also early purple orchid, birds' nest orchid, bluebell and wild strawberry. Red squirrels may be glimpsed in the tree canopy.
There are areas where landslips on the steep sides of the gorge have taken trees with them, which adds to the interest of the site. There is a folly, locally known as The Cottage, overlooking the tourist entrance to Marble Arch. This was used for shooting parties in Victorian times and is well worth a visit. this is where the journey ends at the Marble Arch Caves.
Facilities:Car park. The Visitor Centre at the Marble Arch Caves (run by Fermanagh District Council) is open from late March to September, from 10.00 am-4.30/5.00 pm, with toilets, café, guided tours of the caves and shop.
