Stand at the western end of Calle Norzagaray and the Atlantic opens up in front of you, with the long green esplanade below and Castillo San Felipe del Morro sitting at the tip of the islet. Kites lift off the grass most afternoons, and the old city walls run back behind you toward the town.
San Juan rewards travellers who are happy to walk. The historic core is compact and best covered on foot, and the forts, churches, plazas and small museums sit within easy reach of one another. This guide covers the sites named in the source material, ordered so the strongest come first, followed by a plan for a single day.
Top things to do in San Juan
1. Castillo San Felipe del Morro (El Morro)
A 16th-century citadel on the northwestern-most point of the islet of San Juan, part of San Juan National Historic Site and a World Heritage Site. It commands the entrance to San Juan Harbor, and the walk out along Calle Norzagaray to reach it is part of the experience.
Allow at least an hour inside. The extensive esplanade between the citadel and the town is popular for kite flying, so combine the visit with time on the grass. One ticket is good for both Castillos on the same day.
2. Castillo San Cristóbal
One of the largest Spanish fortresses in the New World, built to protect against land-based attacks on the city. It is part of San Juan National Historic Site, and the National Park Service visitor center off Avenida Luis Muñoz Rivera shows an introductory film in English and Spanish, along with exhibits and a bookshop.
Allow at least an hour here too. Because a single ticket covers both forts on the same day, pair this with El Morro rather than splitting them across two days.
3. La Fortaleza
Also known as the Palacio de Santa Catalina, this is the official residence of the Governor of Puerto Rico, at the western end of Calle Fortaleza. It was built between 1533 and 1540 to defend the harbor and is a World Heritage Site.
It is a working residence, so treat it as a building to see from the street as you walk the old town rather than an interior to tour.
4. San Juan Cathedral
On Calle Cristo, the cathedral contains the tomb of the Spanish explorer Juan Ponce de León. It was built in the 1520s, wrecked by a hurricane, rebuilt in 1540, robbed in the late 1500s, damaged by another hurricane in 1615, and restored in 1917.
Tours are given daily from 8:30AM to 4PM. It sits on Calle Cristo, so it fits naturally into a walk that also takes in La Casa del Libro on the same street.
5. San Jose Church
Built in 1523, when it was called the Church and Monastery of Saint Thomas Aquinas. It is the second oldest church in continuous use in the New World and the oldest in the United States. Before Ponce de León was moved to the San Juan Cathedral, his body was buried here for 300 years.
Visit it in the same stretch as the cathedral, since the two are linked by the story of Ponce de León's burial.
6. San Juan National Historic Site
The park takes in multiple sites, including the two Castillos, most of the historic city walls, and tiny Fortín San Juan de la Cruz (el Cañuelo) across the harbor on Isla de Cabras. The main address is 501 Norzagaray St, and the site is open 9AM to 5PM.
Admission is $10 per day for adults, with children under 15 free and national park passes covering up to three visitors. Plan the forts as one continuous outing rather than separate trips.
7. La Casa del Libro
At 255 Calle del Cristo, this is a museum of the art and history of books across five centuries, holding nearly 5,000 early works of manuscripts and books, some from as early as the 15th century. It is best known for two royal mandates signed by Ferdinand and Isabella concerning the arranging of Columbus' fleet for his second voyage.
Open Tuesday to Friday 11AM to 5PM and Saturday 11:30AM to 5:30PM. It is a short stop on Calle del Cristo, so slot it in beside the cathedral.
8. Cuartel de Ballaja (Ballaja Barracks)
Completed in 1863, with a chapel added in 1881, this building once housed military personnel. It is now a museum called Las Americas Museum, containing Caribbean and European American arts and artifacts.
Open Wednesday to Friday 9AM to noon and 1 to 4PM, and Saturday and Sunday 11AM to 4PM. Admission is $6 for adults and $4 for seniors, students and children.
9. Casa Blanca
The ancestral home of the Ponce de Leon family, now a museum, at the western end of Calle San Sebastián. It is a quieter counterpoint to the forts and fits the same Ponce de León thread as the cathedral and San Jose Church.
Open Wednesday to Sunday 8:30AM to noon and 1:30 to 4PM. Admission is $5 for adults and $3 for seniors, students and children.
10. La Princesa
Built in 1837, this structure overlooks San Juan Bay and has landscaped grounds, surrounded by a wall and containing a fountain, sculpture and even a former municipal jail in the courtyard. It sits at 2 Paseo de la Princesa.
Open Monday to Friday from 8AM to 4:30PM. It is a natural pause on a walk along the waterfront.
11. Felisa Rincón de Gautier Museum
At 51 Calle Caleta de San Juan, this museum commemorates Felisa Rincón, who served as mayor of San Juan for 22 years between 1946 and 1968. It occupies a 300-year-old building.
Open Monday to Friday 9AM to 4PM, and free to enter. It is close to the San Juan Gate, so combine the two.
12. San Juan Gate
At the western end of Caleta de San Juan, this was the traditional entrance to the city. It is a quick stop rather than a long visit.
Walk through it on your way between the waterfront and the streets of the old town, and pair it with the Felisa Rincón de Gautier Museum nearby.
13. La Casa Estrecha (the narrow house)
At 101 Calle Tetuan, this home built into a former alleyway is just over 5 ft (1.5 m) wide and easy to miss, so watch for the bright yellow and green front. It is free to walk by, with a nominal fee to enter, and reportedly has great views from the upper level.
Look for it deliberately rather than expecting to stumble across it, since its whole appeal is how little of it there is to see from the street.
14. Museo de Arte (Museum of Art)
At 299 Av. José de Diego in Santurce, this is Puerto Rico's most important gallery, opened in 2000 as a showcase for the island's cultural heritage. Admission is $15 for adults, $12 for residents, and $5 for seniors, students, children, veterans and disabled visitors, with $3 extra for the temporary exhibits.
Open Wednesday, Friday, Saturday and Sunday 10AM to 5PM and Thursday 10AM to 8PM. All exhibits are free on Thursday 5PM to 8PM, and the sculpture garden is free, open Monday to Friday 8AM to 5:30PM and Saturday and Sunday 11AM to 5PM.
15. Balneario el Escambrón
In Puerta de Tierra, this is the most accessible area of beach to hotel guests, a five-minute leisurely walk from the hotels. The family-friendly beach is protected from the waves by a coral reef, and in the smooth water you can see many fish.
From the beach there are distant views of both San Cristobal fort and El Morro when there is no fog. Right next to the Kiosko Escambrón, a snack bar that often plays loud salsa and serves drinks to locals, there is a lookout point facing the water.
If you only have one day
Morning. Start at Castillo San Cristóbal when it opens, using the National Park Service visitor center off Avenida Luis Muñoz Rivera for the introductory film and exhibits. Then walk the old town on foot, taking in San Juan Cathedral on Calle Cristo and San Jose Church, and stopping at La Casa del Libro on the same street if it is open.
Afternoon. Continue to Cuartel de Ballaja and Casa Blanca, then follow Calle Norzagaray out to Castillo San Felipe del Morro. Your single ticket covers both Castillos on the same day, so keep both forts within this one day. Allow at least an hour at El Morro, and spend some time on the esplanade between the citadel and the town.
Evening. Walk back through San Juan Gate at the western end of Caleta de San Juan, and finish at La Princesa on Paseo de la Princesa overlooking the bay, which is open until 4:30PM on weekdays, so plan this as a late-afternoon stop before the light goes.
Frequently asked questions
Do I need a separate ticket for each fort?
No. One ticket is good for both Castillos on the same day, and admission to San Juan National Historic Site is $10 per day for adults, with children under 15 free. National park passes include up to three visitors.
How should I get around the old city?
The narrow streets of Old San Juan are packed with people, so it is recommended to experience Old San Juan by foot in order to avoid too much traffic. You can take a taxi for less than $20 from most hotels, or the B21 bus for $0.75, which picks up from many locations near the hotels.
Which day is best for the Museo de Arte?
All exhibits are free on Thursday from 5PM to 8PM, when the museum is open until 8PM. On other days it opens 10AM to 5PM, and the sculpture garden is free during its own hours.
Are there beaches within walking distance of the hotels?
Yes. In Puerta de Tierra, Balneario el Escambrón is the most accessible area of beach to hotel guests, a five-minute leisurely walk from the hotels. The beaches in Condado and Isla Verde are the other options named in the source material.
Decide which fort you want to see first, check the days the smaller museums are open, and build your San Juan itinerary around a single walkable day in the old city.
