Arroo Mountain [Sliabh Aradh]

About Arroo Mountain [Sliabh Aradh]

Standing as a prominent Marilyn above the Glencar Valley, this broad, peat-clad plateau offers a wilder experience than its more famous neighbours. While the summit is relatively flat, the southern edges provide dramatic views over the limestone cliffs of Eagle's Rock. It is a quintessential wild bog walk requiring good navigation.

Did You Know?

• •The name Sliabh Aradh translates from Irish as 'Mountain of the Ladder'. This likely refers to the steep, stepped limestone tiers that define the southern face of the Dartry range, which resemble a giant staircase when viewed from the valley below.
• •From the summit, the view is dominated by the distinctively shaped 'prow' of Benwiskin to the west and the massive bulk of Truskmore to the east, often identifiable by its prominent telecommunications mast.
• •The mountain is home to Eagle's Rock, a 330-metre limestone pillar located on its slopes. It is a massive free-standing rock pinnacle that stands proud of the main plateau cliff-line, formed by ancient landslide activity.
• •The summit plateau is so notoriously boggy and featureless that reaching the highest point often feels less like hillwalking and more like a high-stakes game of tactical puddle-jumping.
