The distinctive El archo rock formation

The arch of Cabo San Lucas, is a distinctive rock formation at the southern tip of Cabo San Lucas, which is itself the extreme southern end of Mexico's Baja California Peninsula. The arch is locally known as 'El Arco.'

It is here that the Pacific Ocean becomes the Gulf of California.

This area is widely used in hotel advertising in the Los Cabos Corridor. This spot is a popular gathering area for sea lions and is frequented by tourists. It is three stories tall and was formed from natural erosion. The Arch of Cabo San Lucas is adjacent to Lovers Beach on the Sea of Cortez side and Divorce Beach on the rougher Pacific Ocean side.

Basement rock in Los Cabos formed through intrusive igneous processes c. 115 million years ago, during the Cretaceous period.[1]
