Popular coolcation destinations range widely. In the Nordic countries—Iceland, Norway, Sweden and Finland—travellers can explore fjords, wander through quiet forests or, later in the year, chase the Northern Lights. The Alps offer crisp, high-altitude air, long hiking trails and the novelty of staying in places such as igloos. Canada provides vast stretches of northern wilderness, ideal for exploration without the oppressive heat found further south. The United Kingdom and Ireland, with their rolling green hills, rugged coastlines and deep historical roots, offer a gentler kind of summer escape. Meanwhile, the Baltic countries—Estonia, Latvia and Lithuania—are becoming increasingly popular, their cool breezes from the Baltic Sea offering welcome relief as temperatures rise elsewhere.
