The best way to get to the Basilica Cistern is to take a tram to Sultanahmet where this is located directly in the centre. It is only a 5 minute walk between the Haghia Sofia and the Basilica Cistern. Once you arrive there is usually a queue of people lining out of the door of the building which is directly over the cistern. When I was there, a travel guide spotted that I was foreign and offered to bypass the queue and go straight inside. I declined this offer as it usually very cheap to get inside and the queue will not take long so do not panic and fall for offers such as this!
The picture above shows the columns in the cistern, each 9m high and spaced 4.5m apart. You can see the reflection of the ceiling in the shallow water that fills the floor space surrounded by paths. If you look closely when you visit you will be able to see fish swim in these waters!
