If you want to get around Vancouver easily, then you will want to take the SkyTrain around the city. Launched in 1986, SkyTrain is the oldest and one of the longest fully-automated, driverless, rapid transit systems in the world. It runs on a guide way, high above city streets, though there are a few stations located underground. The Blue and Red Lines connect downtown Vancouver with the cities of Burnaby and Surrey. The Green Line connects downtown Vancouver to the Vancouver International Airport and the city of Richmond. You can buy a day pass which can take you around the city as well as provide you with side trips to the North Shore with the ferry ( 轮渡 ). You can also ride Vancouver’s metro bus system and travel around downtown, and many other beautiful areas. If you are visiting Vancouver, the SkyTrain is your best bet at seeing every corner of the city. You can buy SkyTrain day passes at most grocery stores like Safeway and Save on Foods. You can also purchase passes at the SkyTrain station and the Ferry terminal.
