Dominica, known as the “Nature Island of the Caribbean,” is a haven for eco-tourists and adventure seekers. Nestled between the French islands of Guadeloupe and Martinique, this lush island boasts a remarkable landscape of volcanic mountains, dense rainforests, and stunning waterfalls. Dominica’s most iconic natural wonder is the Boiling Lake, the second-largest hot spring in the world.

Hong Kong is one of the few places in the world where a 700-year-old fishing village sits minutes away from the headquarters of international banks. Once a British colony and now a Special Administrative Region of China, the city carries traces of Cantonese, colonial, and global influences in its streets, rituals, and food. The city has more than 300 hiking trails, including the well-known Lion Rock hike, which ends at a dramatic cliff overlooking Kowloon’s dense skyline.

ABERDEEN -- Scotland's third-largest city (pop. 187,000) is characterized by buildings of beautiful white granite. Set beside the North Sea, Aberdeen is both a university town and the capital of the Scottish oil boom. It is also one of Scotland's largest seaside resorts (though its appeal is confined to those who like their water well-chilled).

What sets Kaikōura apart are the extraordinary marine encounters that begin just off the shoreline. The Kaikōura Canyon, an underwater gorge that plunges to great depths close to land, creates currents rich with nutrients that attract a remarkable array of sea life year-round. Sperm whales are a common sight here and are frequently spotted on local boat tours. Dusky dolphins twist and leap in large pods, and colonies of New Zealand fur seals laze on rocky outcrops along the coast.
