Castillo de San Felipe de Barajas
Best time to visit
Go early at 8 AM opening to beat both the heat and the crowds. Late afternoons around 4 PM also work well with softer golden light for photos.
Budget tips
Entry costs about 25,000 COP (roughly $6 USD) for adults. Bring cash as card machines sometimes fail, and consider the combined ticket with the Palacio de la Inquisición if you want two sites for one price.

About
Quick facts: Perched on a 50-meter hill overlooking Cartagena's old city, this fortress spans 10,000 square meters with a network of underground tunnels stretching over 2 kilometers. Soldiers once used these tunnels to move supplies and spring surprise attacks, with clever acoustic designs that let them hear enemies approaching from any direction.
Highlights: The tunnels are the real showstopper: a cool, dark labyrinth where your footsteps echo and the temperature drops 10 degrees the moment you descend. Strategically built with angled walls and listening posts, a whisper at one end can be heard clearly 60 meters away, making it nearly impossible for invaders to sneak through undetected.
Insider tips
- Wear sturdy closed-toe shoes: the ramps are steep and uneven in places.
- Head straight to the tunnel network first before tour groups arrive for a spookier, quieter experience.
- Bring water and a small towel or fan, the Cartagena heat is relentless with little shade on the upper terraces.
- The best photo spot is from the top sentry point facing west, capturing the old city walls meeting the sea at sunset.
