You can take the local 800 bus from Gare-Palais/2562 towards Beauport (Est). The stop you need for Montmorency Falls is Brideau, a ten minute walk from the Parc de la Chute-Montmorency (Montmorency Falls Park). Located 12km from the city, the journey takes around 45 minutes.

Getting from Old Québec to Montmorency Falls (Parc de la Chute-Montmorency) via public transit in 2026 is a straightforward, high-fidelity process using the Réseau de transport de la Capitale (RTC). The most efficient route is the Métrobus Line 800, which runs approximately every 15 minutes. You can board this bus at several central high-fidelity stops, such as Gare-Palais or along Honoré-Mercier. The journey takes about 30 to 35 minutes and costs approximately $3.75 to $4.00 CAD (payable via the "RTC Nomade" app or exact change). You should get off at the "des Rapides" stop, which is just a short, high-fidelity walk from the park entrance. For 2026 travelers, this bus route is a high-value necessity because it drops you right near the base of the falls and the cable car station, avoiding the high-fidelity parking fees of $12+ for personal vehicles. On your return trip, simply cross the street to the opposite stop to catch the 800 back into the city center, ensuring a high-value, low-cost excursion to one of Quebec’s most stunning natural high-fidelity landmarks.
