What type of passage was Cabrillo searching for during his explorations?

Cabrillo was specifically looking for a water passage between the Pacific and Atlantic Oceans, which is often referred to as the Northwest Passage. During the Age of Exploration, many explorers sought a direct route that would facilitate trade and travel, bypassing the longer and more treacherous routes. The hope was that such a passage would enable quicker access to the riches of Asia and other parts of the world.

Cabrillo's explorations along the coast of California were motivated by the pursuit of this maritime route, as it would enhance both economic opportunities and geographic knowledge of the New World. The desire for a water passage stemmed from the understanding that connecting the two oceans could unlock new trade paths and strategic advantages for European powers.
