One of your first stops should be Interpretation and Welcome Center. Here, you'll be able to orient yourself and pick up some great ideas before you set out exploring.
It's always a bonus to discover places that don't charge an admission fee when you're on vacation. After you've taken in all that's on offer at this free tourist information center in Mingan, why not head over to Patterson Lake? Not too far from Interpretation and Welcome Center, it's the perfect addition to your itinerary.
