Taejongdae Danubi Train runs along the sea through Taejongdae Resort Park in Yeongdo, Busan. Riders can get off at three stops — the observatory, Yeongdo Lighthouse and Taejongsa — look around, then continue on the next train. Unmanned vending machines at each stop sell one-way tickets on site. The train has no air conditioning, so it is hot on sweltering days.
