1900 Ocean Drive
We went on day with no events being held, only cost $3 a car to get in, then just regular penny cost. 8/1/09
If you go when activities are being held at the fort be prepared to pay the $13 or $16 to get in, there is no way around this even if you are camping in the area. The machine works great and the people are very friendly. Also, there is day use fee of $3.
5/31/10--Day use fee up to $5.
