OrlyBus

€11 OrlyBus drops you straight at Denfert‑Rochereau in 30–40 minutes

OrlyBus runs from all ORY terminals (1, 2, 3, 4) to Place Denfert‑Rochereau in southern Paris for about $11–12, with a single, luggage‑friendly ride and no tram or RER changes. First departures are around 05:30, last runs close to 00:30, so it covers almost all regular flight banks.

Buses run every 8–10 minutes at peak but can stretch to 15–20 minutes late at night, so just missing one around 23:30 can mean a noticeable wait in front of Terminals 3–4. The same 8–20 minute pattern applies in the city direction from Denfert‑Rochereau back to Orly.

Advertised travel time is 30 minutes, but Reddit and FlyerTalk regulars report 45–50 minutes during weekday rush hour on the A6 into Paris. A Google reviewer mentioned one ride pushing close to an hour in heavy traffic, still calling it decent value compared with an Uber quote at the same time.

Tickets run roughly €11–€12 one way, payable at airport machines, some ticket counters, or on apps; factor in card fees if you’re paying in dollars. Compared with a €30–€50 taxi from Orly to Denfert‑Rochereau, OrlyBus usually wins for solo travelers or pairs trying to keep costs down.

Denfert‑Rochereau is the only stop and connects you straight to Metro lines 4 and 6 plus RER B within about 150–250 meters of the bus bay. The downside: reviews flag that the OrlyBus stop there has limited seating and shelter, so a 15–20 minute wait in winter rain is not fun.

Overcrowding pops up in reviews when several flights dump into Terminals 1–4 at once; racks and the aisle fill with 23 kg suitcases, and late boarders sometimes get turned away to the next bus. Locals on r/paris suggest grabbing a seat near the front so you can be among the first off and hit the metro stairs ahead of the pack.

Step-by-step: using OrlyBus at ORY

• 1. Land and follow signs: From Terminals 1, 2, 3, or 4, follow “OrlyBus / Paris” signs toward the ground transport area; walking time is usually under 10 minutes from most gates.
• 2. Buy your ticket: Use the OrlyBus ticket machines near the stop to pay about €11–€12 by card or contactless; keep the receipt or QR code handy for inspection.
• 3. Find the right stop: Look specifically for buses marked “OrlyBus – Paris Denfert‑Rochereau” to avoid mixing it up with local RATP routes at the same curb.
• 4. Board and stash luggage: Get on through the front door, store big bags on the interior racks, and grab a seat toward the front if you want to exit quickly in Paris.
• 5. Ride into town: Expect 30–40 minutes off‑peak, but budget up to 50–60 minutes between about 07:30–10:00 and 17:00–19:30 when the A6 clogs.
• 6. Arrive at Denfert‑Rochereau: The bus drops you at the dedicated bay near Place Denfert‑Rochereau; from there it’s a short walk to Metro lines 4, 6, or RER B entrances.
• 7. Connect or walk to your stay: If your hotel is close to Denfert‑Rochereau, you can be checking in within 5–15 minutes on foot; otherwise transfer to the metro with the same luggage in hand.

One practical tip: before committing, check Google Maps traffic on the A6; if it shows deep red and a 50–60 minute bus ride, consider tram T7 plus Metro or RER B instead.
