A glacially-carved valley in the Wicklow Mountains, home to a 6th-century monastic city, a perfectly-preserved round tower, two dark lakes, and nine waymarked trails that range from easy lakeside strolls to strenuous clifftop hikes.
The signature hike: 9.5 km, strenuous, ~3 hr 15 min. Climbs steeply past the Miners' Village, crosses a footbridge over the Glenealo River, then follows a boardwalk with 600+ steps onto the Spinc cliffs. Panoramic valley views and herds of Sika deer. Hiking boots and rain gear essential.
An easy 5 km linear walk (~1 hr) along the southern shore of the Upper Lake through Scots pine woodland. Passes the ruined Miners' Village and offers views of St Kevin's Bed — the cave where the saint reputedly lived — across the lake. Look for feral goats and peregrine falcons.
A gentle 3 km loop (~45 min) on mostly flat ground. Winds through oak woodlands and onto a boardwalk across the Lower Lake wetlands — the best spot for dragonflies, lizards, and spectacular valley views. A short detour leads to the Monastic City.
A moderate 8 km loop (~2 hr) climbing 160 m around the shoulder of Derrybawn Mountain. Offers wonderful elevated views over both lakes, the monastic settlement, and Laragh village. Red squirrels and treecreepers are common. Note: re-routed to bypass Poulanass waterfall due to storm damage.
A short but steep 1.6 km loop (~45 min) climbing 90 m to view the Poulanass Waterfall and its plunge pools. Part of the path has collapsed — walkers must return down the steps and follow re-routed silver arrows through oak and mixed woodland.
Founded by St Kevin in the 6th century, this is one of Ireland's most important early Christian sites. Explore the round tower, stone churches, decorated crosses, and the interpretive exhibition. Guided tours available by booking. The monuments and lakes are free and open 24/7 year-round.
The longest trail at 11.5 km, strenuous (~4 hr 15 min, 490 m climb). Follows the Spinc boardwalk then branches towards Lugduff and Mullacor mountains before linking with the Wicklow Way back. Excellent for spotting deer, ravens, merlins, and kestrels.
