World's Most-Visited Tourist Attractions

No. 35 Eiffel Tower, Paris

Annual Visitors: 6,700,000

This iron-lattice structure looms large in the collective imagination—and literally towers over Paris’s historic heart, never out of sight for long. Last year, 6.7 million paid to ascend the Eiffel Tower, and the savviest beat the crowds by purchasing tickets online in advance. Admire the Champs de Mars and surrounding streets spreading out below as you ride a glass elevator to the highest viewing level at 540 feet. —Kate Appleton
