San Juan Sightseeing: Forts and Museums

October 19, 2026

Sightseeing in San Juan centres on Old San Juan, where Spanish fortifications, a cathedral, a governor’s mansion and two museums sit within a short walk of each other. Santurce adds an art museum and street murals. Prices are in US dollars, and the heat is strongest at midday, so start early. Atlantic hurricane season runs from 1 June to 30 November.

Castillo San Felipe del Morro

Construction of El Morro began in 1539. It is part of San Juan National Historic Site, along with San Cristóbal and the city walls. One $10 ticket covers both forts for 24 hours, for ages 16 and over, with children 15 and under free. Payment is by card only and the forts are open daily from 9am to 5pm, closed on Thanksgiving, 25 December and 1 January. The big lawn in front of El Morro has been closed for turf replacement since April 2026. The forts stay open, but see the National Park Service fees page for the lawn’s status. No vehicles are allowed on the El Morro grounds.

Castillo San Cristóbal

San Cristóbal dates from 1634 and was rebuilt through the 1780s. It covers 27 acres, and the National Park Service calls it the largest fortification the Spanish built in the New World. It has countermine and troop tunnels to walk through. The city wall was completed in 1678, and the walls are tall sandstone. The forts are just under a mile apart, about 15 to 20 minutes on foot along the wall. Read the park’s history of the site before you go.

Catedral de San Juan Bautista

The cathedral at 151 to 153 Calle del Cristo holds a marble tomb reported to be that of Juan Ponce de León, and the glass-case remains of San Pío. It is an active church, so dress with covered shoulders and knees. Opening hours differ between sources, so confirm before you go.

La Fortaleza and the Paseo de la Princesa

La Fortaleza, built in 1533, is the governor’s residence. Free guided tours of about 30 minutes are reported on weekdays from 8:15am to 3:30pm. You need photo ID, and because the schedule changes daily, call ahead. The Paseo de la Princesa is a promenade of about 300 metres along the south wall, open at any hour and ending at the Raíces Fountain beside the Puerta de San Juan.

Museums

Museo de las Américas on the second floor of the Cuartel de Ballajá charges $8 for adults and $5 for seniors, children and students. It is open Tuesday to Friday from 9am to noon and 1 to 4pm, and weekends from 11am to 4pm. See its visit page . Museo de Arte de Puerto Rico at 299 Avenida de Diego in Santurce is open Wednesday to Sunday, until 8pm on Thursday, and is free on Thursday from 5 to 8pm, though that can change. Adult admission is listed at about $17, so check the museum’s fee page .

Calle Cerra murals

Calle Cerra in Santurce is known for its street murals. A guided mural walk by The Art Walk Puerto Rico runs for about 90 minutes.
