The caves of Hercules, located just 14kms west of Tangiers, are a place of stunning natural beauty and great archeological significance.
Apparently, this is where the mythical figure, Hercules, used to rest after finishing his 12 labours.
The mouths of the caves open up onto the Atlantic and are flooded at high tide. When the tide comes in, water gushes up through these massive holes in the ground and hillside. It's very impressive.
The caves are partly man-made and partly natural. It's not exactly sure how the caves were created. It's believed that for some reason, an ancient civilization used to carve millstones out of the solid rock that caused giant caves to form over the years. How these primitive people managed to cut into solid rock with simple and crude tools is still a mystery.
At low tide, the views inside caves looking out over the ocean are stunning, the colours in particular. The blue Atlantic Ocean and sky above resemble a reverse silhouette of Africa.
Swimming here can be quite dangerous. The currents offshore can get very strong. If you're not a strong swimmer, it's best to stick to sunbathing.
Some people say that the caves were once joined under the sea to St Michaels caves on the rock of Gibraltar and that this is "possibly" how the Barbary Apes crossed over. But nobody knows for sure. This coastline is also where the pirates of the region were once headquartered.
Also well worth a visit is the old 2nd and 3rd century Roman ruins of Cotta. They're just 500 feet away.
