Gotland, Sweden’s largest island, sits in the Baltic Sea and feels like a world of its own. Its main town, Visby, is a UNESCO World Heritage site and one of the best-preserved medieval towns in Northern Europe. Surrounded by a 3.5-kilometer stone wall with original towers still intact, Visby once served as a key Hanseatic trading hub. Visitors can walk along cobbled streets lined with rose-covered cottages, explore Gothic church ruins, and climb up the city wall for views over the harbor.

St. Vincent & the Grenadines is a Caribbean nation that feels both adventurous and serene, a chain of lush islands and tiny cays scattered across turquoise waters.

Niagara Falls, New York, is home to one of the most powerful natural spectacles in North America.
