Perched right on La Caleta beach, the Castillo de Santa Catalina offers some of the most stunning panoramic views you'll find of the bay and the city. It's more than just a historic fortress; it's a place where you can feel the sea breeze and soak in centuries of history. Wander through its star-shaped ramparts and discover the various exhibition halls and cultural events often held within its ancient walls. It's the perfect spot to catch a breathtaking sunset before heading back into the city.
