Other forms: pilgrims
You might be a Muslim on your way to Mecca, or a Hindu going to the Ganges, or a Christian traveling to Lourdes. When you make a reverent journey to a place you consider sacred, you're a pilgrim.
You can also use the word less seriously and call yourself a pilgrim when you make the trip to Graceland for Elvis Week. Another kind of pilgrim (often spelled with a capital P) are the Puritans who fled religious persecution in Europe, came over on the Mayflower, and founded Plymouth Colony, in Massachusetts. The word comes from the Latin peregrinus, "foreign," or "a foreigner," and if you just travel to foreign countries, you’re a pilgrim, too.
