11. Grand Canyon, USA

The greatest natural attraction in the United States, the Grand Canyon is a key sight for all travelers planning their lifetime of adventures. Standing on the rim of the Grand Canyon, looking out over the carved landscape, will awaken your senses.
Several hikes in the canyon and along the rim offer unique perspectives. Walk even a short distance down the Bright Angel trail to gain additional views and to experience what the canyon is like below the rim.
For even more adventure plan a rafting trip down the Colorado River through the canyon.
The Grand Canyon looks different throughout the day and at different times of the year. One trip is never enough. If you are going to add this place to your to-see list, consider what you want to do here to determine the best time to visit.

12. Stonehenge, England

Stonehenge is one of those places that makes you ponder what went on here over 4,500 years ago. It's long been a mystery to historians, and has captured the imagination of countless visitors. Despite the large number of tourists that descend on Stonehenge, the place still has a mystical feel.
At the site, giant stones, some standing, some fallen, are set in two roughly circular patterns that are oriented to highlight the summer and winter solstices. For a truly memorable experience, plan your visit during one of these times.
An easy day trip from London, Stonehenge can easily be worked into your UK itinerary.

13. Borobudur, Indonesia

Set in a steamy jungle with three volcanoes providing the backdrop, Borobudur is Indonesia's top tourist attraction.
Borobudur dates from the 9th century and is one of the largest Buddhist temples in the world. It's a fascinating place to wander about. Over 500 Buddhas are spread around the site, some of which sit under ornate stupas.
Try to visit early in the morning when you'll have the best chance of experiencing a bit of early mist, and the view to the volcanoes will be the clearest.
