The Brisbane River flows from the Brisbane-Cooyar Mountains of Brisbane-Kuyar to the southeast and northeast to Moreton Bay. It is 344 kilometres long and admits the Stanley and Bremer rivers. The Brisbane River is navigable for ships in the lower reaches of Brisbane. The Brisbane River winds through the city of Brisbane and flows into the Pacific Ocean 15 kilometers away. Brisbane is also known as the City of Rivers because of the beautiful scenery it brings to the city. The Brisbane River, like a bright ribbon, slowly drifts down from the hills to the sky, across the reddish and green fields, winding and winding. After several S-shaped rounds in the urban area, it floats and disappears in the distant valleys. Bus ferries on the Brisbane River are mainly three types of ships - "City Ferry, City Cat and City Hopper. Ferry is a simple ferry, running back and forth between Thornton Street, Eagle Street and Holman Street on Thornton Street, Eagle Street and Holman Street in downtown. It stops every 10 minutes when there is a Hopper. There is usually only one crew member on board. Besides driving and selling tickets, when the boat comes ashore, it has to set a springboard for passengers to get on and off the boat; Cat is not a simple one. It's a water bus. It's a long journey between the University of Queensland and Hamilton. There are 18 docks on both sides of the river. It takes an hour and 25 minutes to walk one way. There are three crew members on board, one at the helm, one at the ticket sale, and one at the passenger's boarding and disembarking. Hopper is our tourist's favorite free sightseeing boat, going back and forth to Sydn Street. Between ey St and North Quay, it takes about 42 minutes to run one way, with six docks in between. From Sydney Street on Sydney Street, they are Dockside, Story Bridge, Holman Street on Holman Street, Eagle Street on Eagle Street on Eagle Street, Thornton Street, Captain Cook Bridge on Sunton Street, Captain Cook Bridge on Cook Bridge, Maritime Museum, and then Friendship Bridge. Goodwill Bridge, to South Bank 3 on the South Bank, and finally to North Quay, visible in front of Victoria Bridge, Victoria Bridge. Hopper works every half hour, Sydney Street shift at 6:00, last shift at 23:30; North Pier shift at 6:15, last shift at 23:45, and there is usually only one staff member on board. Besides not selling tickets, other work is the same as Ferry. When we ride in Hopper, Uncle Captain takes time to do toilet disinfection work. Take City Hopper, you must first look at the timetable, and then see the big red cruise ship, there are "kangaroo" signs and "City Hopper" words on the ship, do not mistake on other Ferry or Cat, that's a fee. We took a free sightseeing boat, City Hopper, to the north, east, through the story bridge, south, to the end of Sydney Street, and then, without getting off the boat, we returned all the way to Pier 3, South Bank, and South Bank Park.
