If you hate the idea of having your shoes melt into the asphalt, consider visiting the Catacombs in late spring or early fall. However, in summer, a Catacombs tour is a welcome respite from the intense heat. A winter visit to the Catacombs can be tricky because most of them are closed for at least a portion of the season. To avoid disappointment, do your research ahead of time to find out which Catacombs are available for tours during this time.
The best way to reach the Catacombs is by bus. Bus 118 takes a circular route past the Colosseum, down Appian Way, with stops in front of the Catacombs. Cycling is also an option, especially on Sundays when there is less traffic.
The standard entry ticket for adults is priced at €8 whereas it costs €5 for children aged between 7 to 16 years old.
It may take anywhere between 40 minutes to an hour to take a Catacomb tour. It does get cold with temperatures dropping to 16 ° C or 60 ° F accompanied by high humidity, so dress accordingly.
