The Castillo is rather large and many parts (such as the gun deck) are not handicap and stroller accessible. There are lots of little rooms to explore and peek into. There is a map room which tells the story of the different flags that have flown over the Castillo through out history. The fort was never taken by force, but it has withstood many battles. There are several cannon ball impressions left in the rock wall from battles past. This the oldest fort standing in the US, so it is rather unique in construction and layout.
The Fort is located on a bit of grassy hill. It is a perfect spot to throw down a blanket for a nice picnic and watch the boats in the bay. In the past there has been a historic ship in the harbor, although I was unable to see one on this trip.
We spent about an hour or two wandering through the fort, watching the reenactments and got to watch and hear a real cannon fire. We later took a leisurely stroll through the historic downtown and treated ourselves to some ice cream.
The four of us absolutely loved it and hope we can come back again for another wonderful trip. For more information please visit their website at; http://www.nps.gov/casa/index.htm.
