The BUTI or Busan City Tour Bus is by far the most cost efficient option for tourists and foreign nationals looking to find their way around Busan from one point to another. The best part, with one ticket you have access to all four lines, covering almost all major seashore and cultural attractions in the city. There are four different lines and routes to choose from, so you can select the line and the route that best suits your needs depending upon your schedule. In case you need to transfer buses, your pass will give you free transfers from one line to another for up to 24 hours after you've used your pass. It's the perfect way to discover the parts of Busan you want to see, and set your own pace on the tours and other activities. All this comes at a great price only available for tourists, so you can't miss out.
