These sightseeing buses normally follow a fixed route with several stops near popular attractions, landmarks, and tourist areas. Passengers can board at a designated stop and get off whenever they want to explore an area. During the journey, a hop on hop off bus tour gives travelers the opportunity to continue sightseeing without arranging separate transportation for every attraction. After exploring a stop, passengers can return to the designated route and wait for the next available bus according to the published schedule.
