17 Best Things to do in Old San Juan

1. Calle Fortaleza and the Governor’s Mansion

Head to Calle Fortaleza, the most famous street in all of Old San Juan.

The old cobble stoned street is lined with beautifully painted pastel colored buildings and at the end of the street you will see the Governor’s mansion. Calle Fortaleza usually has decorations hanging overhead too making this street one of the most photographed!

The Governor’s mansion is a 16th century building that was remodeled in the 1800’s and is the residence of the governor of Puerto Rico.

2. Castillo San Felipe del Morro

Castillo San Felipe del Morro, the historic fort of San Juan is a must a one of the top things to do in Old San Juan. El Morro (for short) is set on top of a cliff overlooking the Atlantic ocean at the entrance to San Juan Bay and dates back to 1589.

The fort was constructed to keep the Spanish colonial port safe from enemies. Over the centuries the fort was added to and became much bigger than the original plans. Today the site is a National Park, a UNESCO World Heritage Site and preserved as a museum.

Visit El Morro to learn a bit about San Juan and Puerto Rican history. The views alone are worth the visit!

3. Castillo San Cristóbal

While you are visiting El Morro don’t forget to also see Castillo San Cristóbal, another fort not far from Castillo San Felipe del Morro. This UNESCO World Heritage Site started construction in 1765 and was built to protect Old San Juan from a land invasion.

Brent and I ran out of time and we weren’t able to get here but if you loved El Morro, definitely check out Castillo San Crisóbal as well.

4. Puerta De San Juan

The entrance to the walled city of Old San Juan! Puerta De San Juan was constructed in 1635 and served as the main entry into the walled city during the Spanish colonial era. After you walk through the Puerta De San Juan continue along the Passeo del Morro.

Fun Fact: the gate is 16 feet tall and 20 feet thick!

5. Passeo del Morro

Passeo del Morro is a beautiful walkway around the walled city of Old San Juan. You can start the Passeo del Morro along the Bay of San Juan and continue along where you’ll be next to the towering walls of Castillo San Felipe del Morro.

My favorite way to get to the Passeo del Morro is from the San Juan Bautista Cathedral, walk down Caleta de San Juan and then through the Puerta De San Juan. Once you pass through the gate turn right to walk towards Castillo San Felipe del Morro.

Consider visiting the Save a Gato center (a non-profit organization dedicated to the welfare and care of the cats of Old San Juan) and donating!

6. Explore the Colorful Streets of Old San Juan

Get your walking shoes on! Old San Juan is best discovered on foot and one of my favorite things to do in Old San Juan. There are so many nooks and crannies to be discovered and so many beautiful bright colored buildings to admire!

Don’t Forget to Look Down! The blue cobblestone streets are very old! The stones were brought over from Spain when the island of Puerto Rico was colonized by Spain and the stones were laid for roads starting in 1784. Over the years the stones have had to be replaced by new ones but you can still spot the original cobblestones on many streets.

7. Take Photo’s at the PR Flag on Calle San Jose

The Puerto Rico Flag painting is a great photo opportunity! The PR flag is painted on an old crumbling building on Calle San Jose. I recommend coming early in the morning to be sure there aren’t others waiting to take pictures here too!

8. San Juan Bautista Cathedral

While walking around Old San Juan, don’t forget to walk past the San Juan Bautista Cathedral – the oldest church on US soil! This beautiful cathedral is in the center of Old San Juan on Calle de Cristo and is definitely worth walking by or walking into! 

The entrance to the Cathedral is free.

9. Try a Piña Colada from Barrachina

There is an argument about who was the first person to invent the Piña Colada. Caribe Hilton AND Barrachina both claim to be the first one to make Puerto Rico’s national cocktail!

Barrachina is a restaurant and bar located on Calle Fortaleza in Old San Juan. Stop by and try one (or two) piña coladas for yourself! (and then go to the Caribe Hilton and try one there and let me know which you think is better!)

10. Bar Hop around Calle San Sebastian

If you like to drink… bar hopping can’t be skipped over. This is one of the funnest things to do in Old San Juan.

  1. We love visiting San Juan! We travel there often and especially enjoy enchanting old San Juan. There are so many unique and interesting things to experience there. The Paseo del Morro is a fabulous walk and we love the uniqueness of it with the cat sanctuary.
    There are many cats living in the rocks along the walk and it’s so fun to spot one here and there nestled in the mangroves.
    Don’t forget to stop by for a photo at the red door and a pina coloda at Bhrrachinos😊.
