Best Activities in San Juan Puerto Rico

Forts in San Juan Puerto Rico

San Juan has a very nice collection of historic forts.  Since the Spanish controlled Puerto Rico for hundreds of years, they spent a lot of money and years constructing forts for protection.

San Juan was where these castillos (fortified buildings in Spanish) were needed in order to defend the San Juan Bay and the much-desired island of Puerto Rico, the foothold for control of shipping throughout the Caribbean.  Today, Puerto Rico is a territory of the US and the forts are National Park Tourist Sites.

Castillo San Felipe del Morro: El Morro

The entrance to El Morro is a beautiful park that is frequented by picnickers and kite-flyers and located at the northwest tip of Old San Juan.  The grassy area is a tranquil and spacious place for families to relax and enjoy the sea breeze while watching the cruise ships sail into the port of San Juan.  There are no visions of the past soldiers marching across the grassy field in a land attack.

Beyond the field and sitting high on the overlook is the El Morro fort.  From its high perch over the sea, the fort was able to defend the city and ward off all naval attacks.  In order to defend the San Juan harbor, Spain built El Morro from the 16th until the 18th century.  It consists of 6 levels containing dungeons, barracks, and storerooms.

While walking along its ramparts on the 60-foot outer walls you can still see the sentry posts and canons pointed out to look out over the water.  

The view of the harbor is beautiful.  We watched for a while and saw the next Royal Caribbean cruise ship sailing toward the fort and then through the harbor to the port for its next round of passengers.

Castillo de San Cristobal: San Cristobal

In order to protect the walled city of San Juan from a land attack, the Spanish built San Cristobal over a period of 150 years. With an area of 27 acres, it is the largest fortification in the New World and is now a UNESCO World Heritage Site.

The view of the Old San Juan Coast and up to Condado is gorgeous.  Take a tour to see where some of the Spanish-American War took place and to stand in the Devil’s Sentry Box, where legend says that many soldiers disappeared without a trace.

Santa María Magdalena de Pazzis Cemetery

lots of old cemetary headstones in a cemetary overlooking the blue water-Santa María Magdalena de Pazzis Cemetery in Old San Juan

Our mouths dropped when we got our first view of the Santa Maria Magdalena de Pazzis colonial-era Cemetery.  This memorial park is a highly sought-after resting place in Puerto Rico.  It has to be one of the most beautiful cemeteries in the world with one of the most spectacular gravesite views!  The dead are graced by the oceanfront view and the sounds of the families frolicking in the El Morro fortress fields nearby.

Unfortunately, the gates were closed on the day we toured that area, so we could only get views from the city wall gates and from the ramparts off of El Morro.

La Perla: of Despacito fame

Our next stop was La Perla, however, it had begun to rain, so we only drove through the town in our tour guide’s car.  It would have been nice to get out and snap some photos of this colorful town, but I am not sure the locals would have liked that too much.D 2.0

La Perla is a shantytown in the north of San Juan.  It was established in the 18th century as a slaughterhouse and cemetery – since those were forbidden inside the old city walls.  La Perla became the home for former slaves and homeless wanderers.

Puerto Rico’s only slum area is colorful and cluttered, with narrow one-way streets and homes stacked upon homes.  La Perla received recognition from being featured in the song, Despacito, due to local musical stars Luis Fonsi and Daddy Yankee and rose to further international fame with the addition of Justin Bieber to the mix.

Old San Juan City Walls

Old City Walls loom high above the walkways of Old San Juan

The Spanish began erecting masonry walls around San Juan in the 16th century.  The walls, which were as tall as 100 feet and 50 feet wide at the base, provided the much-needed fortification and protection of the city from attackers.  The city was totally enclosed by the end of the 18th century.  There were 5 city gates providing the only way in or out of the city of San Juan.

Today, the remaining 2 ½ miles of city walls are a part of the National Park System and are maintained by expert masonry workers to preserve the historical look of the walls.

Paseo de la Princesa

The Paseo de la Princesa was not on my original one-day itinerary for old San Juan.  However, the guide knew that I loved markets, and since it was Sunday there was a big one set up on one of the most scenic walkways in the world.  The walkway is lined by the old city wall and ends at the historic San Juan gate.

The promenade, which dates all the way back to the 1800s, has fountains, street vendors, sculptures, and a beautiful view of the San Juan Bay.  On weekends, the entertainment is turned up with live music and even more local vendors selling authentic Puerto Rican goods at their craft stalls in the street market.

La Princesa is located on the walkway.  It is an old prison that now serves as the headquarters for the Puerto Rico Tourism Company as well as housing a unique Puerto Rican art exhibit that is worth taking a look at.  For tourists, they offer maps and informational brochures with city guides


Raices Fountain

Raices Fountain, a beautiful site to see while you explore San Juan Puerto Rico!

The beautiful fountain overlooking the water at the end of the Paseo de la Princesa is the Raices Fountain.  It is a popular place to watch the sunset over the water.

It was added to the promenade in 1992 to commemorate the 500-year anniversary of Spain’s discovery of America in the New World.  The fountain adds an artistic flair to the area while displaying Puerto Rican heritage.  The bronze figures represent Puerto Rico’s culture and the European, African, and Taino (the indigenous people of the Caribbean) ethnic roots.

Wander around the colorful streets of Old San Juan for a day

Colorful streets in Old San Juan

Everything in Old San Juan is vibrant and colorful.  The historic buildings are lively blue, the antique entranceways and pillars are purple, and up on the balcony railings are cheerful yellow flowers cascading down into the streets. 

On your Old San Juan day trip, spend some time exploring the old cobblestone streets and meandering from one shop to another, finding souvenirs and treasures of Puerto Rico and sampling authentic street food.  

Fortaleza Street, Calle Fortaleza, is the main street in Old San Juan, the most visited street in the capital, and perhaps the street that is the most photogenic and full of life.  We spent many hours on this street since it is where our Old San Juan Hotel was located. It often is often called Umbrella Street for its frequent artistic display of a colorful umbrella canopy.

El Capitolio – The Capitol Building of Puerto Rico

El Capitolio is located in San Juan, the capital of Puerto Rico.  It houses the offices of the senators and representatives.  In the middle of the building, it has a dome on top with a huge rotunda where the constitution for Puerto Rico is displayed.  Guided tours are offered during the day.

It has two entrances with 8 pillars and 7 doors which represent the seven senatorial districts that existed when the building was completed.  Active travelers like my daughters can go to the backside of the building and get their exercise as they run up and down the many steps that lead up to El Capitolio!

Plaza San Juan Bautista

The San Juan Baustista Plaza is located in front of the Capitol.  It is a modern architectural structure that overlooks a nice beach.  The plaza has benches to sit and relax while enjoying the spectacular view of the ocean.

Surrounding the San Juan Plaza are colorful mosaics of the coat of arms of each of the towns in Puerto Rico.  They make a nice display around the Statue of Juan Baptiste.

Standing tall at the entrance to Playa Pena and in the middle of the San Juan Plaza is a statue of Juan Baptiste, the patron saint of Puerto Rico.  Christopher Columbus first gave the island the name of San Juan Bautista when he arrived in 1493.  Saint John the Baptist was considered a prophet of God by many faiths and washed the followers of Jesus in the Jordan River.

Playa Pena – Beach in Old San Juan

Beach in San Juan Puerto Rico

While most people frequent the popular beach resorts at Condado and Isla Verde, few tourists know about Playa Pena.  They would be surprised to know there is a beautiful beach right in Old San Juan.  We found this gem right across from the Capitol Building.  There was a nice overlook at the top where we captured some great photos.  We then accessed the beach by the paved staircase, walked along the fine sand, and perched on one of the many large rocks on the shore. 

The waves were crashing in hard when we were there in the wintertime.  It does have a small natural reef that protects the shore so it might be a good swimming beach in milder summer months.  It is definitely very photogenic and great for catching some Caribbean sun rays. 

Paseo de los Presidentes – Walkway of Presidents

We found the Walkway of the Presidents along the roadway across from the south side of the Capitol Building on Avenida de la Constitucion.  The bronze statues are larger than life.  I know this for sure because they were all taller than my 6-foot hubby! 

There are 9 figures of the presidents who have made official visits to Puerto Rico during their presidency including Teddy Roosevelt, Herbert Hoover, Franklin D. Roosevelt, Harry Truman, Dwight Eisenhower, John F. Kennedy, Lyndon Johnson, Gerald Ford, and Barack Obama.

Holocaust Memorial

A little further down the road on Avenida de la Constitucion we found the San Juan Holocaust Memorial titled “In the Shadow of Their Absence”.  It is a moving memorial that represents those that suffered and lost their lives during that terrible time in history.

Bahia Urbana Waterfront & San Juan Cruise Port Terminal

The San Juan Bay waterfront has been redesigned into a magnificent public space with grassy park areas, sculptures, flower beds, an outdoor bar, sandbox, a carousel, fountain, amphitheater, and benches for relaxing and enjoying beautiful views of the bay. 

This is where the smaller cruise ships dock so there are several piers spread out along the promenade.  There is even a dock being used for some watercraft tours.  The area is especially lively on weekends when ships are docked in the ports. I especially loved walking around and seeing all the vendors that set up their stalls to display their wares for the cruisers!

Of course, you should also include a stop in San Juan Puerto Rico at the Instagram-worthy I Heart PR sign that is located on the waterfront. We were able to snap a few photos in between the raindrops!
