The average depth of the ocean is about 3.7 miles (6 kilometers). However, this average depth is deceiving. There are some parts of the ocean that are much deeper than this. In fact, there are some parts of the ocean that are so deep that we have not even been able to reach them with our deepest diving vehicles.
