What is the term for a journey to a sacred place?

The term "pilgrimage" specifically refers to a journey undertaken to a sacred place or shrine, often for spiritual or religious reasons. This journey is usually motivated by the desire for personal growth, seeking forgiveness, fulfilling a religious obligation, or seeking a connection with the divine.

In contrast, while "excursion," "expedition," and "trek" refer to various types of journeys or trips, they do not carry the same religious or spiritual connotation. An excursion is generally a short trip for leisure or educational purposes, an expedition usually involves a journey for a specific purpose, often related to exploration or research, and a trek implies a long and challenging journey, often through difficult terrain. None of these terms encapsulate the spiritual significance that a pilgrimage holds, making "pilgrimage" the most accurate choice for a journey to a sacred place.
