Poulanass Waterfall

• Walk the signed Pink Route, about 1.6 km and roughly 45 minutes, graded moderate with somewhere around 80 to 90 m of climb.
• Take the short steep ascent beside the falls, pausing at the plunge pools where the water gathers between the steps.
• Continue above the waterfall, then descend through woodland back toward the valley floor.
• Fold it into a longer day, since it links easily with the bigger valley walks and the lakeside routes rather than standing alone.

The gorge is shaded and green, so soft overcast light suits it better than harsh midday sun. Slower shutter speeds work nicely on the tiered water, and the ground above the falls gives you the wider valley shot. Keep your ears open on the woodland section too, where woodland birdsong is often the main company, though nothing is guaranteed on a short walk.

• Sturdy shoes or boots with decent grip, the single most useful thing you can pack.
• A rain layer, since the woodland stays damp and the steps hold water.
• Water and a snack, as there is nothing at the falls.
• A reminder that paid parking applies at the Upper Lake if you start there.

This is a small waterfall in a well-visited valley, so if you arrive expecting a big dramatic drop you will come away underwhelmed, especially in dry spells when the flow drops. The opening climb is short but steep, and the terrain is the main limitation: steps, uneven stone and slippery surfaces need care and steady footing. Treat it as a short, scenic add-on woven into a longer Glendalough walk and it earns its place.
