Castillo San Felipe de Barajas is the monument that tells you why Cartagena looks the way it does. Spain shipped the gold and silver of its American colonies through this harbour, and pirates and rival navies came for it again and again, so the crown turned the hill of San Lázaro, just outside the walled city, into a fortress of sloping stone. It grew over the 17th and 18th centuries into a maze of batteries, ramps and narrow tunnels designed to carry sound and confuse attackers, and locals still call it the unconquerable, because it never fell. Today it is part of the UNESCO-listed port and fortifications and the best viewpoint over the old town and the bay. The Tiqets ticket we link bundles castle entry with a three-hour guided walk that starts in the plazas and murals of Getsemaní and climbs to the fort, so you get the story, not just the stones. It is the single best way to understand Cartagena on your first day.
How it works: the tour is run by Colombian Trips Travel and meets at Plaza de la Trinidad in Getsemaní, where the guide holds a black umbrella. Groups are capped at fifteen and are guided in English or Spanish. Castle entry, the live guide and gratuities are included, while hotel transfers and drinks are not. You can cancel or reschedule for free up to twelve hours before the start, and you show the ticket on your phone.
What to expect: the walk follows Getsemaní’s lanes, with their murals, flags and umbrellas strung overhead, then crosses to the foot of the hill and the statue of Blas de Lezo, the one-legged, one-eyed admiral who defended the city against a huge British fleet in 1741. Inside the fortress you climb ramps to the upper batteries for wide views over the old town, Bocagrande’s towers and the bay, and duck into the tunnels, which are narrow, low and dimly lit. The castle opens daily from morning to late afternoon; foreign visitors pay a higher rate than Colombians, which the bundle covers.
Making the most of it: there is little shade on the ramparts, and the midday heat is punishing, so book an early or late slot, wear a hat and carry water. Good shoes help on the steep stone ramps. If you are claustrophobic, skip the deeper tunnels and enjoy the views instead.

Good questions
Is castle entry included in the Tiqets ticket?+
Yes, the San Felipe Castle and Getsemaní ticket includes entry to the fortress as well as the live guide. Hotel transfers, food and drinks are not included.
Where does the tour start?+
It meets at Plaza de la Trinidad in Getsemaní, where the guide carries a black umbrella. From there you walk through the neighbourhood to the castle.
Was the castle ever captured?+
No, it is famous as the fortress that never fell, most notably during the British siege of 1741. That record is why Cartagenians still call it the unconquerable.
Are the tunnels suitable for everyone?+
They are narrow, low and dimly lit, so they are not ideal for anyone claustrophobic or with limited mobility. You can enjoy the ramparts and views without going deep inside.
How hot does it get at the castle?+
Very hot, because there is little shade on the stone ramps and batteries. Go early or late in the day and carry plenty of water.
