Pack light, breathable clothing along with one warmer layer for cool evenings, comfortable closed-toe shoes for walking, and a shawl or covering for church visits (shoulders and knees should be covered inside sacred sites). A compact umbrella or light rain jacket, a hat, sunglasses, and sunscreen are also good ideas, along with a universal power adapter. Pack any medications in your carry-on, labeled with your name, and don’t forget your rosary.

Gratuities are appreciated but not required. As a general guideline, per person: $8 to $10 a day for your tour manager, who travels with you for the whole pilgrimage; $2 to $4 for each day with a local guide (about $2 for a half day, $4 for a full day); and $6 to $8 a day for your driver, assuming you’re happy with the service. If you’re not sure which currency to use, see “Should I tip in dollars or local currency?”

This can vary by trip, so always check your pilgrimage’s Inclusions and Not Included lists. As a general rule, though, everything is included except tips for your local guide, tour manager, and bus driver, those are left to your discretion (see “Are tips expected, and how much?” for suggested amounts).
