Glendalough
National park · Ireland

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.
