About

A tucked-away Coillte woodland in rural Cork where the Glashagarriff River tumbles over Poulanassig Waterfall into a deep, folklore-rich pool — a short, rewarding loop walk for those who don't mind muddy boots.

Things to Do

Poulanassig Waterfall

The thundering centrepiece of the wood, 0.75 km west of the car park. Water crashes over large blackened boulders into a pool whose bottom, according to local legend, cannot be found. Best viewed after rain, when the flow is strongest. You can scramble down to the water's edge for a paddle or wild swim.

Lower Trail & River Walk

A more natural, muddy path that drops steeply from the car park and meanders alongside the Glashagarriff River. You'll pass small cascades, amber-hued shallows, and moss-covered boulders. The path can be very muddy in winter or after rain — sturdy footwear is essential.

Lower Trail & River Walk

Wild Swimming

The pool beneath Poulanassig Waterfall is deep enough for a refreshing dip, especially in summer when the shallower water warms faster. Watch your footing — the rocks are coated in slippery biofilm. Enter with care.

Wild Swimming

Upper Trail Walk

A flat, hardcore-surfaced path cut into the valley side, offering balcony-like views down through the tree canopy to the river below. It leads all the way behind the waterfall before descending to connect with the lower path. Great for those wanting solid footing and panoramic woodland views.

Aghavrin Clapper Bridge

At the eastern end of the wood, the remains of a traditional stone clapper bridge — flat slabs on stone piers — once used by locals to cross the Glashagarriff. Partially collapsed from flood damage, it's still a fascinating historic feature worth seeking out.

Geological Formations

Imposing rock outcrops are scattered throughout the wood, most notably along the upper trail. The steep-sided gorge, carved by the Glashagarriff River, creates a dramatic natural amphitheatre around the waterfall.

Plan Your Visit

  • Hours: No formal opening hours — the wood is an open public site owned by Coillte. Accessible year-round during daylight hours.
  • Admission: Free entry
  • Parking: Free roadside lay-by at Aghavrin crossroads, with space for about 5–7 cars. From Coachford, head west on the R618 for ~2.7 km, then turn north at Glashagarriff Bridge.
  • Food: No food or drink available on site. The nearest shops and pubs are in Coachford village, roughly 4 km south-east. Bring your own supplies and water.
