What Is a Slot Canyon?

A slot canyon is a narrow, deep gorge with high walls and a tight passageway, usually formed by water erosion over thousands of years.

In San Diego, slot canyons are typically made of sandstone or siltstone and can be explored by hikers of all skill levels—depending on the trail.
