Did you visit Parc Mauricie the same day you drove from Montreal to Quebec City? Was that doable and still allowed you to spend time in the parc? How long were you at the parc? Thanks.
It depends on what you wish to do. It takes roughly 2 hours door to door from Montreal to the Park and the same from the Park to Quebec City. You can drive through the Park in roughly one hour ( it is a horseshoe shape with entry points at both ends) but doing so won't really allow you to see the vistas and sites. To enjoy these, you must get off the main road and enter specific areas. You could, for example, enter through the St-Mathieu gate and go swimming in the Wapizagonke Falls. It's an easy 10 minute hike from the parking to the falls, which you walk up to find a spot to swim in its shallow pools. If swimming isn't your thing, there are canoe rentals all around the park and hiking trails for everyone. So can it be done in a day? yes, with some planning and at least 4 hours alloted to the park itself (that would include entry process and finding your way in and out). Enjoy!
We drove from Quebec! If you leave early enough you could do it. It took about two hours to get back to Quebec. Plan on visiting the park for two to three hours,
As @PRockwater mentioned, it takes about 2 hours from Montreal. I left Montreal around 10am and found that I didn't have enough time to spend in the park to do all the hiking that I wanted. (If hiking is your thing, I would say that the more challenging and rewarding trails are near the Saint-Jean-Des-Piles entrance [East], while the St-Mathieu entrance [West] has the shallow pools/swimming at Les Cascades.) Definitely doable in 1 day, if you plan to only spend a few hours hours in the park.
