Figuring out transportation is often one of the most stressful parts of a vacation. It's expensive, time-consuming, and difficult to find safe, comfortable seats.

However, if you make transportation the focal point of your trip, it becomes an exciting vacation where you can see plenty of great things, whether scenic landscape or inner-city attractions. By riding the bus routes, you can experience the city like a local, taking in all the overlooked sights that the tourists often avoid.

Traveling by bus is a great way to experience many places. You'll see sights that you can't when flying between destinations, and you don't have to worry about the driving and navigation. When you're behind the wheel, it's harder to truly enjoy the sights around you.

It also helps if there's a tour guide who can point out all the fantastic sights and landmarks along the way, telling you the history and significance behind each one.

Bus tours are also more affordable than other types of tours. The cost of running a bus tour isn't as expensive as a flight or taxi.

For your next vacation, don't overlook the beauty and magic of taking a bus ride all over the world. Here are some of the best bus tours on the list.
