You must take a boat to go, otherwise you can't see it. The ticket 40 is very cheap, but the ticket is 70. I don't know why it is set like this. The 40 ticket is a pass. It can be done before 4 o'clock. It takes about 3 hours to get down in a circle. There are many people on the holiday. It will be full for a while. If you are full, you can also charter your own boat. It is about 300.
