We rented an apartment across the street from Fort. We spent an afternoon walking around the fort. The historical information is well documented. The views from the top are astounding. My grown son and his girlfriend loved learning about the history of Old San Juan.

San Cristobal is every bit as scenic as El Morro, but receives only a handful of visitors each day. If it seems to far from where you're at, hop on the free trolley and get off at stop 18b, tour the fort while avoiding the crowds.

For only $3 admission, we toured the entire huge fort. This is a MUST visit when in Old San Juan. What is not frequently advertised is the fact that there is FREE trolley service in the city, one takes you in the inner city and the other to the forts.

Nice, historical site. Lots and lots of walking. They encourage you to be hydrated, but don't allow you to bring in water.

I recommend getting there early as the sun can be pretty brutal. You will need sunscreen for this walking trip. There is so much history surrounding this place that a wiki would do a much better job. Cheap and fun time.

The views from the top were amazing and the historic info was very interesting. It was interesting that it was still used in WWII. Also found the drawings of sailing ships in one of the holding cells amazingly detailed.

If you are interested in history and like to visit old forts, this is the place for you. This was a perfect stop for us on our self-directed walking tour of Old San Juan. There are some exhibits about the history of the fort. You also get some great views of the city and the ocean from this location.

We were lucky to have a ranger give us an explanation of the history of the fort before we began wandering on our own. Lots to see and explore. Lots of reading. Dungeons were interesting. Views were fantastic as you climbed to the top. There is a free shuttle that will take you to El Morro, which is another must... More

This is definitely worth checking out. Its a winding fort that you are able to fully explore. The views are great and lots of interesting history. If you are in Old San Juan I would highly recommend a few hours here.
