The Catacombs of Saint Callixtus are cool, literally and figuratively but the tour experience could have been better
You need to purchase a timed-entry ticket to see the catacombs. This is a guided experience so don’t expect to wander on your own or even linger. My tour guide was informative but not what I would call an expert on the catacombs or giving tours/moving groups. There were some questions that he either didn’t have the answer or seemed to struggle to answer. We passed by some areas that had very interesting drawings and symbols, it would have been nice to have time to look at them and receive information. Because the halls are so narrow and the groups can be large if you linger you will miss what the tour guide is describing up ahead. My tour guide also did not engage the visitors. Smaller groups, training the guides on tour techniques and visitor engagement could have made the experience so much better.
Right now there is only a small area of the overall catacombs that are open to the public. What you do see is interesting. But do a bit of research on the catacombs especially the symbols (even if it is only the official website) before going this will enhance your understanding and appreciation …..don’t rely only on the guide.
One last thing, there are no bones in the catacombs so if you are expecting to see bones you will be very disappointed. If you are looking for bones visit the Crypt of the Capuchin Friars.
Some practical things….
The catacombs are outside of Rome. You will need to take public transportation, taxi/Uber, or join a tour company. The nice thing is you get to travel on the Appian Way.
As mentioned you do need a timed-entry ticket. Buy it online.
They are closed on Wednesdays and for some time around lunch so be sure to plan accordingly. Check their website.
The passageways are tight. If you are claustrophobic the catacombs may be a problem.
There are stairs and some are steep. Wear shoes that are stable.
It is cool down there. It is nice during the hot temperatures but a light sweater or shawl might be nice to have on hand.
There is no cafe only a food truck (I didn’t try it so I don’t know how good it is).
Photos are not allowed within the catacombs. Their rule please respect it.
