Sometimes all it takes is a great hotel to change your travel plans. A beautiful location, a relaxing resort, or a cool design hotel can suddenly alter your original itinerary. Here are four stunning places—in Finland, Austria, Argentina, and even Bosnia and Herzegovina—that might cause detours.

Rovaniemi: Head north of Helsinki to find the official home of Santa Claus, every winter sport imaginable, the aurora borealis, and a modern ski lodge near the Arctic Circle.

Bezau: Travel into the Hinterwald to find a design hotel that looks like a chalet, a relaxing bathhouse, a locally sourced restaurant, and stunning views of the mountains in the Alps.

Sarajevo: Visit the Balkans to find a vibrant city, welcoming people, an inclusive Old Town, and a brightly colored hotel in one of the fastest-growing cities in Europe.

Buenos Aires: Find three hotels with three very different personalities—from Belle Époque elegance to a wine theme to eco chic—in one of South America’s hottest destinations.
