We visited the monument during the summer and we came in by the water taxi dock. One of the people that we were visiting with was sore so we went off without her. We went into the forts and looked around and even got to see some of the cannons that would shoot out into the bay. One thing I did learn however is that there is an admission fee to see the monument. Unaware of this we quickly finished our tour and headed for the dock as there were security guards walking the grounds. I can guarantee you that there probably is some fine if you don't pay but we were never caught. It really is something to behold if you are a history freak but I am not so I thought it was pretty cool anyways.
