History stands in front of you and you can enjoy it. You don't have to walk into the fortress to enjoy many scenic spots. It's worth your time and convenience to go inside and outside the fortress. Finding the tram to the fortress (often parked at the main bus terminus) on a free golf cart is good for family outings.
San Juan's historic sites include two ancient fortresses, a $5 ticket for universal use, and a free sightseeing bus to take visitors from one fortress to another. The fortresses are very simple and magnificent. The main tone is black, which is particularly unique against the blue sea.
It's really nice here. There are two big castles. Bell-shaped attic is the feature here. Also, I heard there are many cats. Some streets are paved with blue stones. They are very beautiful. Here you can take a free bus tour. In urban areas, you can take 53, 21 and other buses, 75 cents per person.
If you visit San Juan, you will not miss the National Historic Site of San Juan in the Old City of San Juan, which can last for more than half a day. There are some fortresses and other relics in this area that can be viewed to understand Puerto Rico's history. If the weather is good, you can sit on a large lawn, have a picnic and rest, etc.
It's interesting to learn a lot about European history.
