Stroll through the Paris catacombs

For a slightly macabre adventure, head beneath the ground and explore Paris’ catacombs. When the city’s cemeteries were closed for health reasons in the late 18th century, their contents were moved underground - and you’ll be exploring the intricately stacked bones and skulls - yes really - during your visit.

Tickets have to be pre-booked and get snapped up pretty fast - you’ll need to hop on their website a week before you plan to go. There’s a free audio guide to help you figure out the history behind what you’re seeing.
