Our booklet is bringing to you the world's top sceneries: | |
Grenada Known as the Island of Spice for its abundance of spicy plants and leaves,Grenada is one of the southernmost Windward Islands in the Caribbean Sea.Many of its spices have been destroyed by hurricanes in the last decade,though its spicy relics(遗迹) are still the inspirations of many master chefs worldwide.The central mountainous land's cooler air and waterfalls produce a near-constant cloud cover of freeze. | |
Tucson,Arizona A seeming paradise that claims to have 350sunny days a year,Tucson boasts geological beauty and hiking so fantastic that visitors can be tempted into a false sense of security.Be warned:Get prepared for the heat as it isn't unusual for temperatures to rise higher than 110°F (43°C) in summer months,when the rocks can hold that heat well into the evening hours.Even your hunting dog will get sunburned | |
Southern Belize With flash rainstorms that instantly fill the dirt roads and the wet that makes it one of the greenest places on Earth,this Maya wonderland is home to the longest barrier reef(堡礁) in the Western globe,the unique uropygialis birds and the deepest diving-the Blue Hole.Nonetheless it is the back roads of the Toledo district,where rain forest meets the jungle,that truly inspire awe and joy. | |
Newfoundland,Canada This Canadian province,which sits at the eastern edge of North America,plays the home for 22whale species and dozens of seabirds that play in groups.While the capital city of St.John's can be quite gentle,the actual island of Newfoundland has more extreme and unpredictable weather moods.Don't forget to bring your windbreakers and thick sweaters. | |
Grimsey This island across the Arctic Circle is the northernmost point of inhabitable space in Iceland.It is a small,rocky island with little vegetation,only a few hundred permanent residents,and cliffs teeming with arctic birds known as puffins,which seem insensitive to the local extreme chill as they dive-bomb from high on the rocks into the Arctic Ocean for food. | |
Cuenca,Spain Uniquely known as the walled city because of its"hanging houses"atop (or actually part of) walls carved out of a rocky hillside in the 15th century,Cuenca's castle-like front sits above the Jucar River Valley,attracting visitors worldwide.The houses,which bake in the high summer temperatures,are now home to an abstract art museum reached by crossing a wooden pedestrian swinging bridge. |
