Independence Hall in Philadelphia is one of the most important sites in US history, being the site where the nation declared (宣布) independence from Great Britain on 4 July 1776. The hall is now part of Independence National Historical Park, which also includes many important sites such as Congress Hall and Liberty Bell Center.

Mesa Verde National Park

Mesa Verde National Park is a Native American site, including 600 well-protected houses dating back to 600 AD. Mesa Verde National Park was once the home of the Pueblos, a Native American people who lived there for over 700 years before moving to New Mexico and Arizona.

Historic Jamestowne

It was in Historic Jamestowne in 1607 that the English set up their first successful colony (殖民地) in America. Today, Jamestowne forms part of Colonial National Historical Park, a historic site which includes YorkTown Battlefield, Colonial Parkway and the Cape Henry Memorial.

【推荐3】What do you think of when you hear the word Australia? Kangaroos and beaches? We’ve rounded up some top Aussie travel bloggers who have given us their trips about the best places to visit in Australia.

Blue Mountains

If you’re looking for a dose of nature, the Blue Mountains are for you. Make sure you have time to visit Wentworth Falls. This spot offers walks of varying difficulty with appealing views of the waterfall, and it’s just a short drive from the main event—The Three sisters. These famous rock formations are the highlight of this picturesque (如画的) postcard area. If you head to Echo Point, don’t miss the Science Railway—the steepest passenger railway in the world.

Sydney

Sydney is filled with beautiful beaches, fun activities and good food. One of the best ways to view the beauty of Sydney is by taking a relaxing walk. An amazing beach walk, and one of the best, is from Bondi Beach to Coogee Beach. It offers extremely pleasant views of the area’s famous rocky beach, thin beach and sandy beach.

Byron Bay

Byron is one of Australia’s top tourist destinations. From countless waterfalls and swimming holes to mountains and bushwalks, this small region hides so much beauty. I would suggest starting with a hike to the bottom of Minyon Falls for a swim, a hike to the top of Mt Warning for a sunrise, and then a hike to the Natural Arch. These are just some of the most accessible, but there is so much more if you’re willing to explore.

Sunshine Coast

The Sunshine Coast has become one of the most beautiful strips of coastland in Australia, long white beaches lined with health-conscious cafés and boutique clothes shops (精品服装店). When you aren’t absorbing the sunshine on one of the many beaches, you can head out to the hinterland (内陆地区) for a day of mountain hiking or discover the swimming holes and waterfalls with not a soul in sight.
