Does Gare Montparnasse have official luggage lockers?

Most sources say yes — open 7am to 11pm, 72-hour maximum stay, cash only, in three fixed sizes. One review platform contradicts itself on this exact point on its own page, so it's worth confirming current terms at the station counter or signage before assuming card payment or 24-hour access.

Can I store a large suitcase near Montparnasse?

The station's own lockers include a large size. Some partner shop points, including the one closest to the station itself, only accept small and medium bags, so check a location's size limits before booking if you're travelling with a big case.

What happens if storage points are full at peak times?

Paris's official tourism site recommends booking storage in advance, particularly in peak season, because nearby partner spots can fill up. Booking a shop slot ahead of time is the straightforward way around this.

Do I need to store my bag before visiting the Catacombs?

Effectively yes. Large suitcases aren't accepted at the Catacombs' own entrance under general Paris monument security rules, and the site's steep steps and narrow tunnels aren't practical with luggage anyway. Store a large bag beforehand and bring only a small rucksack.

Where to Leave Bags in Montparnasse: Station Lockers vs the App Networks

Gare Montparnasse has its own left-luggage lockers, but they're cash-only and shut at 11pm. Here's when the station is the right answer, and when a shop five minutes away does the job better.

The nearest option

Anyone already standing in Gare Montparnasse has the nearest answer within reach: the station's own left-luggage lockers, open 7am to 11pm with a maximum stay of 72 hours. They're described as cash-only, with three fixed sizes running from a small locker up to one large enough for a full suitcase, which makes them the obvious default for a same-day changeover between trains. One review platform muddies this by both confirming and denying, on the same page, that the station has official storage at all — a sign the details are worth checking against the counter or the signage in Hall 1 rather than taking any single source as final.

Where the station falls short

The lockers' hours are the real limit. Anything that starts before 7am or needs collecting after 11pm gets no help from the station itself, which rules them out for early flights or late arrivals. Cash-only payment is an odd requirement in a city where cards are otherwise standard, and the three fixed dimensions won't suit everything — a bike box, a pushchair, an awkwardly shaped parcel. That gap is exactly what the shop-and-café storage networks exist to fill.

How the shop network works

Radical Storage and its competitors — Bounce, Nannybag, LuggageHero, Stasher — all run on the same mechanic: book a slot online or through an app, walk into a partner shop, café or small hotel, and hand the bag over against a QR code rather than posting it into a locker. The bag sits in the partner's own back room, not a numbered box. Where the networks differ is cover: Radical Storage guarantees up to €3,000 per bag, against €10,000 for Bounce and Nannybag and €12,000 for Stasher, worth knowing if what's inside the case is worth more than a locker's peace of mind.

Five spots worth knowing

Radical Storage runs a string of partner points across the Montparnasse footprint, from right by the station to the market streets and the queue for the Catacombs. None of the five below is ranked above another — each answers a different starting point in the neighbourhood rather than competing for the same trip.

Market days to plan around

Rue Daguerre's market runs most days of the week, Tuesday to Sunday, and reviewers consistently rate it as more genuinely local than the more tourist-heavy Rue Mouffetard — reason enough to walk it without a case in tow. Edgar Quinet's food market keeps a narrower window, Wednesday and Saturday mornings only, with a separate Sunday crafts market taking over the same stretch of boulevard; turn up on the wrong day and you get neither. Either way, threading a wheeled bag between butchers' queues and cheese stalls is exactly the kind of friction a nearby storage point removes before you start.

Before the Catacombs

Paris's museums and monuments generally refuse large suitcases at their own cloakrooms under the Vigipirate security plan, accepting only small rucksacks or cabin-sized bags — the Catacombs, entered near Denfert-Rochereau, are no exception. The descent alone runs to roughly 130 steps into tunnels that stay at 14°C year-round and are reported as wet and slippery underfoot, with around 80 steps back up at the far end; a full suitcase has nowhere to go on that route. Unbooked queues are reported at up to three hours in peak season and at least an hour otherwise, so a timed ticket booked ahead, paired with a bag dropped nearby beforehand, avoids both problems in one move.

Getting to and around Montparnasse

Montparnasse-Bienvenüe is the neighbourhood's hub, connecting metro lines 4, 6, 12 and 13. Arriving from Charles de Gaulle, the RER B reportedly runs directly to Port-Royal in around an hour, putting the southern edge of the quarter within a single journey of the airport. Edgar-Quinet's own stop on line 6 sits right at the market, a few minutes' walk from the main interchange.
