• Arrive early in the morning to enjoy shorter wait times and fewer crowds, especially during peak travel months
• Weekdays like Tuesday and Thursday are less crowded than weekends or Mondays, when many catacombs reopen after closure
• Avoid major holidays and school breaks such as Easter, Christmas, and August, as these periods often sell out weeks in advance
• Spring and autumn offer the best conditions, with manageable crowds and cooler weather for outdoor walking to or from the sites
• Book your tickets at least 7 days ahead, especially for popular sites like San Callisto or for combo tours with the Capuchin Crypt
• Rainy days are perfect for visiting, as catacombs are underground and stay dry, offering a great indoor alternative when the weather turns
• Check each site’s operating days, since not all catacombs follow the same weekly schedule and some close on Mondays or Tuesdays
• Wear sturdy, comfortable shoes as tunnels are uneven, narrow, and can be slippery, especially in humid conditions
• Bring a light jacket since catacomb temperatures stay around 15–17°C and can feel chilly after time underground
• Note accessibility and safety limitations since catacombs involve over 100 steps, no lifts, and are not suitable for wheelchairs or those with claustrophobia
