Plan your dream vacation to one of these excellent destinations.

St. Lucia

Abundant（丰富的） rainforests and splendid mountains are all reasons to visit this Caribbean island. St. Lucia offers the perfect mix of relaxation and adventure. To take in the breathtaking scenery, plan to hike the Piton Mountains or dive in the waters of Anse Chastanet.

Banff. Alberta

This Canadian destination will bring out the explorer in anyone who visits. From hiking and whitewater rafting to skiing and snowboarding, Banff offers travelers an abundance of year-round outdoor activities. The Lake Louise Ski Resort is one of the largest in North America and the striking photo opportunities of the Canadian Rockies from Moraine Lake can’t be underestimated (低估).

Machu Picchu

According to travelers, a visit to this Peruvian UNESCO World Heritage (遗产) site is a once-in-a-lifetime adventure. Located in the Andes Mountains, it is the most familiar icon (象征物) of Inca civilization. Spend a few days accustoming yourself to the altitude in the neighboring city of Cusco, where you can experience a mix of Incan and Spanish cultures.

Great Barrier Reef

It’s easy to see why the Great Barrier Reef is one of the Seven Natural Wonders of the World – it stretches nearly 1,500 miles along the eastern coastline of Australia and features about 3,000 reefs, 900 islands and more than 1,500 species of fish. Travelers can see these amazing natural structures from the air or underwater. However, large amounts of coral bleaching (褪色) caused by rising ocean temperatures put this place’s continued existence at risk, so plan your visit soon to see this awesome sight up close.
