This is a very nice 90 minutes site. It’s a fascinating fort with underground tunnels and plenty to explore and imagine. The signage is great and to the point so you leave feeling more knowledgeable without too much work. The volunteers teaching kids (and adults) to create historical letters were so generous and lovely.

Relatively easy to get around here with a stroller as most of it is accessible friendly. Restrooms were clean though not air conditioned. Changing station inside both male and female restrooms. Total time needed here was about two hours, with a baby. Could probably do it all in 90 minutes if just adults. Lot of reading material on the left when you first enter and definitely interesting to learn about the history of it.

What a cool place. We got there early and there was no line but it quickly filled up. Be sure to go to the top and take a picture towards the other fort El Morro - just gorgeous. We did not so a tour but found there was plenty to read to give us information.

Easy walk from cruise ship piers. It is uphill some of the way. We docked early morning do the fort was not open yet but we were able to walk around the grounds. The scenery is lovely. It’s worth the walk to look at the ocean from this historic site.

Not too far to walk from the cruise port. Great value entry, both castles (this and El Morro, quite a bit further away) for $10 is excellent. Great views and lots of interesting stuff to see. Particularly liked the use of the informative boards scattered around.

This is a most impressive fort C 1539-1765 located in Old San Juan. there are tunnels, observation posts, mortar shells, cannons, troop quarters, a chapel, etc.... so much to see and enjoy. This fort protected the city from land based attacks as opposed to Castillo San Felipe del Morro having protected the city from sea going enemies. Be sure to wear very sturdy comfortable shoes, stay hydrated and wear a hat as it was sweltering when we went mid April. Adult fee is $20.00 which allows entrance to Castillo San Felipe del Morro within a 48 hour period. Hours are from 9 to 5 every day of the week. Great photo ops!!

Interesting fort that is attached by a wall to el morro fort. They were built starting in the 1500’s by the Spanish. Whats interesting is that it was fortified more during WWII. If you like history this place is for you! $10 will get you in both forts and there is a boardwalk from one to the other.

Great trip. We arrived at approximately 2 pm and made our way inside the fort. Our admission ticket covered admission into both Castillo San Felipe del Morro and Castillo de San Cristobal which is always a plus. This fort was much smaller than Castillo San Felipe del Morro, but still unique in its own way. There were multiple informational plaques located throughout the fort, that detailed the forts history and significant events that happened in the area. There were many artifacts out for display, including several old cannons. We were able to enjoy picturesque views of the water and marvel at the time and effort it took to build this magnificent structure. This fort also contained several tunnels that were used to travel discreetly throughout the fort during times of battle. Tip: I recommend spending 2 hours here if you truly want to see everything.

We decided to just explore old San Juan on our own during our stop at the cruise port. Walked to Castillo De San Cristobal fort, nice walk not to strenuous but there is some steps and hills to go up. It cost 10 dollars US to enter the fort unless you have the national parks membership. A beautiful scenic fort with lots of history and areas to explore. A must see for all.
