The aquarium can buy annual tickets, because the transportation is convenient, so I bought annual tickets for the aquarium and zoo. There are not only various aquariums here. There are also living corals. There are regular staff to explain the knowledge about the water ratio. It seems that you can buy a pass to Denmark, and you can see the nationals on the train. It seems that you can buy three days to take a bus to various places in Goha. This can save money.
