The onyx black sand of Reynisfjara is formed from volcanic activity in Iceland: when lava collides with the ocean, it rapidly cools and shatters into small fragments of basalt. With its enormous basalt stacks (features in Game of Thrones and once believed to be petrified trolls), roaring Atlantic waves and stunning vistas, Reynisfjara is widely considered to be the most beautiful example of Iceland’s black sand beaches. The sea stacks along the shore are home to thousands of nesting seabirds like puffins, fulmars and guillemots — a must-see for birdwatchers. A visit to Reynisfjara is included in most tours of southern Iceland. Driving here is a good option, too, since it's only about 180 km from Reykjavík.

Portland is home to the nation's largest wooded urban park—Forest Park. A short hike in, and you'll find it hard to believe that civilization is just steps away. With 70 miles of trails winding through the forest and offering views of the Willamette River, you'll often have nature all to yourself. However, you're also likely to run into locals jogging or walking their dogs—expect to be greeted with a friendly "hello." If you have the time, hike up to Pittock Mansion, a stunning French Renaissance-style château that once belonged to Henry Pittock, a prominent publisher and businessman. Today, the mansion serves as a historic house museum open to visitors, offering panoramic views of the city. Another popular destination within Forest Park is the so-called "Witch's Castle"—the moss-covered ruins of an abandoned stone house. Despite its eerie name, there’s no record of witchcraft here. However, legend has it that its original inhabitant was the first person in Oregon to be sentenced to execution for murder in 1859.

Walking tours are great options if you want to quickly orient yourself in a new city within 2–3 hours and meet a couple of fellow travellers. Your Viking guide will make sure you don't walk past any hidden gems and tell you stories of the Vikings, elves and modern-day Icelanders. Some tours might include lunch, others — booze. It's up to you how to stay warm.
