About
Quick facts: Perched on a small island just off the coast, this fortress once guarded Cadiz against naval attacks with canons aimed across the sea. Waves often crash dramatically against its walls, creating a captivating blend of history and nature.
Highlights: Sunsets here paint the sky in fiery hues, beautifully reflected in the water, creating a breathtaking panorama. The lighthouse within the fortress still guides ships at night, a beacon that mixes maritime heritage with romantic views.
Insider tips
- Wear comfortable shoes for walking the rocky causeway from the shore to the fortress.
- Bring a camera for sunset shots from the western parapets, the best spot for panoramic sea views.
- Avoid weekends if possible; weekdays have fewer visitors and more peaceful exploration.
- Check tide schedules since high tides sometimes reach the base of the walls, adding to the dramatic coastal atmosphere.
