Experience the Best of Old San Juan’s Fortifications with Uncle J
If you’re visiting San Juan and craving a deep dive into its historic fortresses, this tour might just be the highlight of your trip. For $39 per person, you get approximately two and a half hours of guided walking through the two most iconic castles: Castillo San Cristobal and Castillo San Felipe del Morro. Led by Uncle J, who dresses as an 18th-century soldier, this tour offers more than just a walk — it’s a lively, engaging journey through the city’s defensive history.
What makes this experience special is the entry to both forts included in the price. Many tours skip one or charge extra, but here, you get a full picture of why these structures are called the “key to the Indies”. Plus, Uncle J’s approach — blending humor, detailed storytelling, and a personal touch — makes history come alive in a way that sticks with you long after the tour ends.
A possible consideration is the physical demands: expect lots of walking, climbing stairs, and potentially limited shade. If you have mobility issues or prefer a more leisurely pace, this is worth bearing in mind.
This tour is ideal for history buffs, photo enthusiasts, and travelers eager to see San Juan’s biggest sights with a knowledgeable guide. If you love a personal connection and insider tips, Uncle J’s small group experience will suit you perfectly.

Starting Point: Castillo San Cristobal
Your journey begins with Castillo San Cristobal, a UNESCO site built to defend against land attacks. Uncle J greets you next to the Christopher Columbus statue in Plaza Colón, setting a friendly tone. You’ll spend about 45 minutes exploring this massive fortress — a true engineering marvel. Clad in colonial attire, Uncle J’s stories illuminate why Cristobal was considered state of the art, with its complex labyrinth of tunnels, ramparts, and lookout points.
Visitors consistently praise the guide’s knowledge, with one reviewer remarking, “Uncle J was a wealth of information. With him being our guide, we learned a lot more about the castles.” The focus here is on understanding how these walls protected the city and their strategic importance in the broader context of Caribbean defenses.
Walking to El Morro
From San Cristobal, the walk along Calle San Sebastian to the next fortress is part of the experience — a chance to soak in the vibrant streets of old San Juan. This walk takes around 15 minutes and is a good opportunity to admire the colorful colonial buildings, boutique shops, and lively atmosphere. Uncle J’s commentary continues along the way, sharing insights about the city’s layout and history.
El Morro: A Majestic Fortress
Once at Castillo San Felipe del Morro, you’ll spend about an hour exploring this six-level fortification. Without giving away all the surprises, it’s enough to say this structure is imposing, with breathtaking views of the Atlantic Ocean. Visitors often comment on how spectacular the panoramas are and how the massive walls seem to blend history with natural beauty.
Uncle J’s storytelling here makes the fortress more than just stone and battlements. Reviewers highlight his ability to balance detailed historical facts with fun anecdotes, making the experience both educational and entertaining. “He explained everything with passion and detail,” one traveler noted.
The Overall Flow and Pacing
The tour’s structure, with strategic stops, ensures you get a comprehensive look at San Juan’s defenses without feeling rushed. The small group format allows Uncle J to tailor the experience, answer questions, and encourage plenty of photo stops. As one review states, “Uncle J kept the tour moving at a nice pace, with breaks when needed, and answered all our questions.”
Practical Considerations
Remember to bring water, wear comfortable shoes, and a hat — especially since the Puerto Rican sun can be intense. The tour does not include the $10 admission fee to each castle, payable at the entrance, but this is a small price for the access and insights you gain. Many guests also appreciated Uncle J’s pre-tour contact via WhatsApp, which made meeting up smoother.
What Travelers Are Saying
The overwhelming majority of reviews are glowing — with a 4.9 out of 5 star rating from 74 travelers — praising Uncle J’s knowledge, humor, and personal touch. Several mention how much they learned, with comments like “This tour is one we will always remember,” and “Uncle J was brilliant.”
Some highlight the physical aspect, noting the amount of walking and stairs; one reviewer aptly said, “Be ready to walk for long distances and climb stairs,” which helps future travelers prepare.
The experience delivers excellent value — combining two major sites, insider stories, and stunning vistas — making it a memorable part of any San Juan visit.
