All aboard buses and trains
Travel purists usually shy away from tour buses. Truly experiencing a place requires doing more than catching a glimpse of the major sights through a bus window. But vehicle-based sightseeing can be a great way to get a visual taste of a place before diving in for a closer look.
Many of the world's best cities have reliable, safe and useful public transportation networks that offer the same type of sightseeing experience as a bus tour, minus the high prices (and the guide). From elevated trains that offer a bird’s-eye view of the streets to ferries that provide awesome skyline panoramas and classic buses that give riders a taste of the most famous urban landmarks, there are plenty of chances to see the best sights in the city for only a few dollars.
