When do the leaves change in Ireland?

Typically September 25–October 15

Sessile oak and holly climb the lower slopes of Torc and Tomies mountains above Lough Leane, one of the largest native oakwoods left in Ireland. Nearby, Reenadinna Wood on the Muckross Peninsula holds a 5,000-year-old yew stand, and arbutus trees drop red, strawberry-like fruit onto the woodland floor as the oaks turn.

Two glacial lakes and the ruins of a sixth-century monastic settlement sit inside a valley of sessile oak, within Wicklow Mountains National Park. A 4.5km valley-floor loop passes the round tower and church walls under turning canopy, and the Spinc boardwalk climbs the ridge above the Upper Lake for a wider view of the color.

A 4km nature trail follows the shore of Lough Veagh through sessile oak, birch and hazel woodland below the quartzite peaks of the Derryveagh Mountains, among the largest stretch of native woodland left in Donegal. At Glenveagh Castle the walled garden, planted with exotics since the 1870s, turns red and gold alongside it, while red deer rut in the glen through October.

Samuel Hayes began planting this arboretum above the River Avonmore in 1777, and the 500-acre estate now holds sequoia, Douglas fir, larch and oak gathered from around the world, some among the tallest trees recorded in Ireland. A 1,440-metre treetop boardwalk threads the canopy near the birthplace of Charles Stewart Parnell.
