Ireland’s historic capital, Dublin, is the perfect introduction to thousands of years of Irish history—and the modern Irish environmental movement. In the Wicklow Mountains south of Dublin, we’ll walk with renowned ecologists among reforesting and rewilding programs in parks, preservation areas and private estates.

On the west coast of the island, Galway is the heart of Irish culture, traditional music, and the Irish language revival. Partnering with experts at the University of Galway, we’ll learn about decarbonization and sustainable transportation initiatives in the city. Then we’ll pay a call to the Carna Research Station outside Connemara National Park to hear from green entrepreneurs and help with marine conservation.

Little known outside Ireland, the spellbinding Sperrin Mountains in County Tyrone are geological cousins to the American Appalachians. During our stay in this rural area, we’ll visit regenerative farms, restored peat bogs, and the island’s largest—and most endangered—lake. On hikes across bright green hills, we’ll see ancient cairns and meet with community groups seeking to preserve the area’s beauty.

Newly famous thanks to the Derry Girls series, Derry/Londonderry is a walkable gem, while Belfast is an emerging hub for greentech. In both cities, efforts to reduce greenhouse gas emissions and adapt to climate change depend on communities transcending historic divisions to work together toward environmental solutions. Seeing how sustainability emerges from social healing in Northern Ireland holds poignant lessons for the United States today.
