Have you ever wanted to feel like you were in a western film? Or maybe you wanted to feel like you were a pioneer traveling the west? It is possible to experience such things during a Wild West vacation! Here are four of the best Wild West vacation locations available:

Walk the Lewis and Clark Trail

Walk some or all of the 3,700 miles trail that was traversed by Mariwether Lewis and William Clark, two of the world’s greatest explorers. Though not all the trails are marked, there are various stops that have been preserved by various historic societies. There is also a coach (长途客车) that makes a 16-day trek following the trail. This begins in St. Louis, Missouri, and ends in Astoria, Oregon.

Venture Route 66

Take a tour or go to see it yourself — ride on the famous Route 66. The road is nearly 2,500 miles long. Harley Davidson offers motorcycle tours that last two weeks. Route 66 will provide an experience that may only be found on the open road. The historic road is still well taken care of.

Visit the Grand Canyon

Visit the greatest canyon in the world, located in Northern Arizona. Raft down the Colorado River, or hike the various trails that run throughout the canyon. If walking is not your thing, there are donkey and horse riding adventures available. In addition, there are motorized boats that float down through the canyon in a week’s time.

Visit Deadwood

Located in South Dakota, Deadwood is a historic landmark. It is the kind of town that comes to mind when one thinks of an old western film. Actors who act as gunslingers (杀手) will often be seen in the streets playing their roles. Winter activities are popular in this old town, and there is always something to do.
