They are also small, dim and strictly managed, and knowing that in advance is most of what makes the visit work.
What you see
A short section of the gallery system is open, with rock-cut niches along the walls where bodies were laid, and larger chambers at intervals. The rest of the network is closed for conservation and safety.
Visits are on a set route with a guide or attendant, in groups, and they are short: fifteen to twenty minutes underground. Photography is generally restricted, which is normal for a fragile rock-cut site.
Hours are the thing to check
This is not an open ruin you can walk into whenever you arrive. The catacombs keep set opening hours and close for periods, and the site can shut at short notice for conservation.
Check before you build a morning around it. Our things to do in Milos page carries the same warning for the same reason: people drive up the hill, find it closed, and blame the island.
What is around it
The site sits in the middle of the Tripiti cluster, which is the island’s half day of culture:
- The Roman theatre, marble-seated, open to wander, a short walk away with the bay in front of it.
- The Venus de Milo find spot, signposted nearby, where the statue was turned up by a farmer in 1820. The statue itself has been in the Louvre ever since.
- Plaka and its castle above, and Klima on the shore below.
Practical notes
- Cool underground, warm on the walk in. A layer helps.
- The approach is on foot from parking above, on a path with steps.
- It is short. Treat it as one element of the Tripiti walk rather than a destination in itself.
Last checked August 2026. Opening hours and access change, and the site can close at short notice - see our editorial policy.
