Ireland has over 30 long-distance well-serviced walking trails, but the diversity of the Dingle Peninsula’s landscape is what makes it an especially remarkable choice. The path travels from one lively village to the next, passing through golden beaches, rugged cliffs, dusty plains, evergreen forests, stone ruins, and fields that are greener than you even thought possible. Trekkers will share the route with wild horses, goats, and sheep, and there’s even a decent climb in Mount Brandon (3,123 feet).
