Quebec Road trip beyond Quebec City
 

Hi,
We have been living in Montreal for a few years but haven't had a chance to go east beyond Quebec City yet. So we are planning a trip this summer to explore more of Quebec.
We have already gone up to Mont Tremblant and surroundings a few times and also been to the Eastern townships, but not this part of Quebec.
We have also visited Quebec city before so this time we will not be spending much time in the city, but in the surroundings.
Following is a little itinerary and plan we made, we can easily add more days if necessary, but I thought a week should be sufficient.
It will be me and my wife, we are in our 30s.

We are looking for some suggestions of any other places in the vicinity to add to our itinerary.
Or any other helpful relevant tips/advice for this trip.

Any help will be appreciated.

Thanks!
